If all you did was switch of the engine light the it was a waste of time
you have to actually fix the reason it failed the test, then reset the light

SOURCE: wont complete scan to pass emission test

When you rest your codes there is a series of tests your ECU has to go through before you can pass emissions. this is done some people can reset the code and go before its sets the code again. on the 96 you can have 2 tests not complete for it to pass. basicly you have to drive the car a couple days for the tests to pass.

check the readiness tests wait until only 2 have not passed. then you should be good.so drive and check.

SOURCE: 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.

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

SOURCE: Check Engine Light won't go off

If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!

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

if you feel ok with it take off the air intake and remove the throttle body to check for any carbine build up. the cause for this code is that the flow for the exhaust is insufficient. also it could be the cad. convertor. you could disconnect the catalectic convertor to see if the code stays gone but I would check for build up first if you do not feel like you can do this see an expert. good luck

2001 300M. Engine Check Light stays on. Passed Emission Tests.


Have you had it reset and it still comes on? there are 8 different systems that need to be monitered, just because it passes emissions doesnt mean you dont have a problem, have someone run the obd2 scanner on it to pull your codes, if nothing comes up , have them cleared and see if the light comes back on.

Emission light comes on


it will not pass the test with the light on, and if u turn off the light they will know when they test it by testing/checking the system readiness function. Go to a Kragen or an Autozone they will run the test to see what trouble code has turned the light on, it is free, post the code back here. Oh have then reset the light after the test.

Check Engine Light Coming On But Now Off


The check engine light comes on to alert the driver that a fault has occurred in the emission control system, if after a pre-determined number of driving cycles the problem is no longer present the powertrain control module will turn the light off, most common cause of intermittent CEL lights is a failing or as we say lazy O2 sensor in the exhaust system.
