Why won't my car pass emissions test even if the check engine light isn't on??


the computer meters fuel based on a signal from the coolant temperature sensor. The check engine light sometimes does not come on when the sensor fails.If the sensor is causing your problem you will have a strong odor of gasoline when the car starts,It will be slow to start the first time, turn it off and it will start right up. lol

How many miles do i need to drive before my buick lesabre reset itself


Unfortunately it is not a certain amount of time or miles that the car needs to be driven.

There are several 'readiness monitors' that basically cover each emissions related system. For instance there is an EVAP monitor that checks the EVAP system and all of it's components under certain specific conditions (No VSS, TPS, O2 sensor, IAT, MAP, Fuel trim, Injector ciruit, EGR pintle position, ECT, or MAF sensor DTC codes set; Start up engine temp 40F-86F; gas tank between 15% and 85% full, Barometer above 75 kPa, system voltage 8V-16V).

So more information is needed as to what failed you the first time. What DTC code was triggered?

If the problem has been fixed right, the history codes will go away after 40 CONSECUTIVE drive cycles WITHOUT the problem re-occurring.

Good Luck.

'07 Sebring failed emissions test twice


There are a lot of issues with this error. Some people are finding that the ecm (main computer) needs to be replaced from corrosion. Others are finding that the ECM can be flashed to another year to fix it. Some are finding corrosion on the connectios. There is a lot of info about it on this page: http://www.sebringclub.net/board/viewtopic.php?f=27&t=11337

Why does my check engine light keep coming on.


The check engine light/service engine soon (yellow light) comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system u will seldom feel the car engine run any different, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

My 2002 Grand Prix GT 3.8L Won't pass emissions. Testing center's scanner says car was recently worked on and that the mileage driven since is not enough to recycle check engine light. The ck eng. light...


Nope, you just need more miles. When the car's computer has been disconnected from power (such as when the battery is unhooked), it'll set what are called "readiness codes" when power is reapplied. It takes a certain number of miles to clear these - some cars require 50 miles, some 100 miles, and some (such as some Isuzu models) need very specific drive cycles to clear them. Once the requisite number of miles have been driven without issues, the readiness codes will extinguish and your car should pass.

1996 doge intrepid wont pass emission test because IM monitors ar


Just maybe your O2 sensors are not operating properly. They may be requiring your engine to heat them up to get upper temperature readings but not lower. You can easily diagnose these and all other sensors and problems by purchasing a Hains manual at your local Auto Zone or Advance auto store which will greatly aide you in diagnosing all your auto needs. And the fault symptom index at the beginning of the book will ease your troubles with professional one on one advice with step by step instructions. Its like having your own ASE certified mechanic at your finger tips. Good luck.
