Emissions Readiness for Arizona Department of Environmental Quality


On- Board Emissions Readiness Monitors-What are they?

It’s that time again, to renew the registration on your car. Many of us have to go to the emission testing location and wait in a long line just to find out if you passed some test to be eligible to renew your registration. What does this test on my car anyway? The test that is performed on your vehicle when they plug it into the computer is to make sure the emission controls on the car are functioning properly.

Background- Starting in 1996 the Government required all vehicle manufactures to include an on-board diagnostic system (OBD) that would monitor and evaluate the emission control systems on the vehicle. Starting in 1996 manufactures switched over to OBD II. This OBD II system will help maintain low emissions and lets the vehicle operator know of any problems with the emission system by illuminating the check engine light.

Why did my vehicle not pass? – Vehicles from model year1996 through 2000 cannot be tested if more than two emission systems are reporting “not ready”. Vehicles 2001 and newer cannot be tested if more than one system reports “not ready”.

What does “not ready” mean? – Not ready status indicates that one or parameters has not been met in order to ensure a system can be accurately tested. This status is watched by a “monitor”. The monitor is a computer program that makes sure the requirements to test the emission system have been met in order to prevent any false readings. There are different monitors for each emission control device on your vehicle, all with different conditions that need to be met in order to be tested.

Why is the monitor not ready? – There are predetermined conditions that are programmed into the monitor that decides when it can run. If these conditions are not met the monitor will stay in a not ready status. It will stay in this status until all conditions are met and a check on the emission system test is ran.

How do I get the monitor to a ready status? – Here is the part that we all want to know. The best thing to do to get your monitors ready is to see a Certified Automotive Technician in your area. There are several things that will need to be check by the Technician to determine what is keeping the monitor in a not ready status. Once the problem is found the Technician can repair the issue and put the vehicle through a drive cycle. This will make sure all the monitors are set to a ready status.

What if I have been locked out of testing? – This can occur for a couple of reasons. If you had an issue repaired, then make sure the check engine light has been turned off and a drive cycle is performed on the car. One of the conditions for a drive cycle to be completed is for the check engine light to be off.

What is a drive cycle? – A drive cycle occurs when the vehicle has met all the required conditions to perform the emission system test. These required conditions are varied from vehicle to vehicle and for each emission control device. Your local area Certified Automotive

Developing Diagnostic Strategies, Using Exhaust Gas Analysis.

Vehicle Inspection Smog/Emissions Repair Mesa, AZ

Emissions repair can be extremely exhausting. A good Technician is one that can diagnose a check engine light, considering that 90 percent of diagnosing a check engine light is emission related.

Examining strategies using 5 gas analysis. Lambda, Combustion Efficiency, Carbon Gases, CAT Efficiency and EVAP Emissions.


-Lambda is perfect air fuel ratio 14.7 parts of air to 1 part of fuel. The closer you get to Lambda, the less carbon emissions. Lambda is a great diagnostic tool, more fuel and less air means rich condition, which will cause the CO and HC gases to be high. We will discuss carbon emissions further in the article.

-Carbon monoxide or (CO), this harmful gas will usually be out of range when there is a fuel problem and the vehicle is rich, considering it is a reading of unburned fuel or raw fuel escaping the tailpipe.

-Hydrocarbons or (HC), this gas is will be seen usually with an ignition problem. HC is read in parts per million or grams per mile. It is the reading of partially burned fuel escaping the tail pipe. Both of these carbon emission gases can be easily diagnosed, using the correct procedure and checks, including your Lambda Numbers.

-Oxides of Nitrogen or (NOX), A gas that has been known to cause acid rain. NOX basically boils down to Cylinder pressure or temperature. The more pressure or heat in the cylinder the higher the NOX will be, If a cylinder exceeds 2,500 degrees the vehicle will produces excessive NOX. This can be achieved in different ways including the exhaust gas recirculation or (EGR) system.

-Catalytic Converter or (CAT) efficiency, the catalytic converter is the most important emissions component on a vehicle with an internal combustion engine. The CAT cleans the carbon emissions to virtually zero when it is 100 Percent efficient. Engineers have created an ozone preserving automotive part, which needs to be in excellent operating condition.

-Evaporation Emissions or (EVAP) one of the most complicated emission repairs, if you do not have the training and equipment. EVAP emissions pollutes the Ozone 10 times more the vehicles tailpipe because to the CAT. Evaporation Emissions is actual fuel vapor that is creating carbon gases. Gasoline is a huge carcinogen, which means it causes cancer and is very harmful, be careful gassing up your ride. The invention of the catalytic converter has significantly reduced tailpipe emissions therefore EVAP emissions is now the major contributor to carbon gases. I have experienced many different problems concerning the EVA P system and have a great skill for Evaporation system diagnosis.
Most importantly, find the proper Free Auto Repair Help to diagnose and repair harmful emissions failures. Not only will this preserve our Ozone, it will also save you money.


The best way to locate a great auto mechanic is to look at their emissions work. If they are not good at diagnosing carbon emission failures and do not have a 5 gas analyzer, then they do not have the training and or equipment to diagnose a drive ability problem or check engine light. I have worked on cars all of my life and currently perform quality auto repair in mesa AZ. In this article I have examined carbon emissions and 5 Gas analysis.


Recommended Vehicle Preventative Maintenance Procedures

Recommended Vehicle Preventative Maintenance Procedures

Oil change, conventional oil, replace every 3k miles, synthetic blend at 5k and full-synthetic around 10K miles. A good full synthetic oil is beneficial to automobile motors. Change a vehicles oil at the recommended mileage, this will prevent engine sludge and oil seal problems. Oil sludge causes motor damage and oil leaks. Many of the cars diagnosed for oil leaks reveal the leak is due to not changing the oil on time. Regardless of oil change habits, vehicles may need more adjustment.

Fuel system service, advanced engineering is making the in-line fuel filter obsolete. In the instance a car has an in-line fuel filter, it should be replace roughly between 19 to 29K miles. Replacing it at the mentioned interval, will add life to the fuel pump. The filter in the tank (Not serviceable), just use some good fuel injector cleaner, this should clean the in-tank fuel filter and injectors, “two for one”. Fuel injector cleaner, does well on vehicles with an in-line filter, just make sure to replace the filter, before using the cleaner.

Cooling system service, this service is due in conjunction with the type of antifreeze the vehicle requires. Reference the vehicle owners manual for the type recommended. De x-Cool is a common type, it is rated to last up to 5 years. Again review the manuals recommended interval, for replacement.

Belts and hoses, these items, replace when needed, unless instructed otherwise, by a car analyst or vehicle diagnostic inspector. The recommended replacement by most belts & hoses manufacturers is 2 years. A quick inspection and analysis of these parts, will prove beneficial.

The Auto Repair Industry – Regular Vehicle Check Ups

The Auto repair industry in Mesa, Arizona. It should involve regular check ups and repair of vehicles to keep the vehicles engine running smooth , motorists should take their vehicles for regular service, after reaching a certain mileage. This ensures that their automobiles remain in perfect working condition.


Engine Systems, OBD Scanner & Diagnostic Auto Codes

The engine systems are quite complicated and one cannot repair it unless they are experts in this field. To begin with, an OBD scanner should be plugged into the automobile’s port to check whether engine light has been set on. All new vehicles use either OBD II systems and customized on-board diagnostic systems. These programs assists in troubleshooting certain fault codes, plus they can report malfunctions, which have been identified by the ECU or computer. The connection port is usually found around driver’s compartment, it could be under the main dashboard.

Check Fault Codes & Sensors, Possible Defective Wiring

Proceed to turn up the device and then check for any fault codes that may be present, its good to remember that codes which are linked with sensors or external wiring wont necessarily show faulty sensors. This may often cause defective wiring portfolio on the sensors, always ensure your systems are updated such that the vehicles firing potential is evenly matched.

Check Main Drive Belts – Regularly Replaced Components

Check and replace your main drive belts, these components must be replaced regularly, check for signs indicative of cracking, uneven wear or tearing. Belts may then be replaced through loosening the tension adjustment unit with a socket wrench.

Oil & Fluid Leaks Should be Regular Checks

Also look for subsidiary gaskets which may be leaking fluid, this could be indicated by drops forming underneath the engine, transmission, or carbon developing around specific oil leaks. When your automobile is leaking, whether its coolant, transmission fluid or motor oil, you could risk engine breakdown. More so when the fluid dwindles to an extent that major functions are hampered. Some gaskets which could effortlessly be changed are the oil pan, valve cover as well as transmission pan. Follow regular maintenance procedures and your car should provide many miles of trouble free service.

Transmission Repair & Services

Not sure what the transmission diagnostic mechanic will tell you? Are you wondering if he is telling the truth? This article is intended to briefly make the reader aware of the average transmission shop. Read More.

1. “Look at all of this metal in the pan.” What a way to sell a transmission, buyer beware. Notice when they show you the pan there is a magnet in the bottom, well this is suppose to keep the metal in the pan and out of the fluid. Some metal shavings is normal. This is why the manufacturer installed the magnet, to prevent the shavings from circulating through the transmission. Transmissions that need to be overhauled will have an outrageous amount of metal shavings and the fluid will be black.

2. “The fluid is discolored or burnt” Now this should be easy to distinguish, look at the fluid yourself.

A. Light Pink = Fluid is Good
B. Pinkish Brown = Service Soon
C. Light Brown = Service Immediately
D. Black = Fluid is Burnt

Take some of your transmission fluid and put it on a piece of white paper or card to tell the color. The service shop will do this for you remember the three colors light pink, light brown and black.

3. “Too may miles, your transmission needs to be overhauled.” This may be the case. Only you and your transmissions know where they have been. The fluid and overall performance is a great hint. Also if you tow or drive like a race car driver you may need a rebuild, beware of who is providing the work and make sure to get a second opinion if not sure.

In conclusion this article was intended for automotive education. All of the readers involved should gain insight on certain transmission shops and the way the sell their products. Please remember these guidelines when consulting an auto repair mechanic.

Automotive Air Conditioning Repair

Is the Arizona heat making your daily commutes uncomfortable due to poor Automotive Air Conditioning. Automotive Engineering offers a free Gear up for summer auto A/C inspection. The automobile air conditioning system needs to be checked on a yearly basis, normally before the hottest time of year, this helps to prevent any major problems, in-turn preserving your AC System. Our inspection includes a complete system analysis and performance check.

Beat the Arizona heat, and learn the basic operating principles of your autos air conditioning system. The automobile ac system can be expensive to repair in some cases. Considering a simple inspection and performance test, may save in time and money. Here are some basic checks that will help aid in producing cold air and cooling your every day drive. Read on.

Make sure the car is blowing air into the cab, start the vehicle and turn the ac on with the air on high. If air is present, is that air cold, cool or warm? Cold air means system if functioning, but may need servicing for even colder air. Cool air indicates that the system needs service, and may have a significant freon leak or weak system. Warm air suggest that your automobile air conditioning system has malfunctioned. With the air still on high, cycle the a/c button or switch on the the air conditioning control panel. Do you hear the compressor switch on and off? This will sound like a loud tick one time under the hood. Thus the same sound should be heard every time you cycle the ac. If the compressor is cycling on and off, but the cab is not cooling, then you may be low on freon.

The system may have air or moister, due to a large freon leak. The system may be inefficient or cold air is not being diverted, this is due to a malfunction in the air ducting via electrical, engine vacuum or control panel failure. A complete inspection of your automobiles cooling system will also play a factor in ac efficiency. Another way to check for a/c efficiency would be to inspect the accumulator with the air conditioning on and running. This component is a cylinder under the hood and may have a sticker on it from the factory. The receiver drier aka accumulator will be cold and may have condensation on it, when the air conditioning system is working properly.

In conclusion preparing your vehicle for the Arizona heat is crucial to get through the summer. In order to have a reliable ride, and a comfortable one, auto air condition and cooling system checks must be performed. These inspections should be performed by a certified auto technician. When performing the checks on your own, take the proper safety precautions, and utilize any information you can gather.
