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.

    sorry for the spelling. its to stop people from reseting the engine light and going to emissions before the code appears again. pre 00 can have 2 not passing and 01 can only have 1 not passing. where 02 and newer has to have all passing.

Probably not a cheap fix.
The car will not pass the test if the light is on during the test.
The light is on when the computer has a problem that will affect emissions or performance.
You would need to have the computer scanned for trouble codes then fix the problem. Once the problem is fixed and the code is erased, the light should stay off.

97 Buick Lesabre, had emmisions test done (which it passed) as soon as leaving emmisions test check engine light came on. Any ideas what may have caused this?


Stop by any good parts store (Autozone, Advance, etc) and have them do a FREE OBII scan. It will read all your fault codes and more than likely light came on because of emission test. But have them read the faults and reset your light.

My 1995 geo prizm lsi engine light came on it runs fine however it failed emmisions testing because nO was twice the limit what could it be


Hi:
You need to find out what is causing the check engine light, to go any further in fixing you car. Most likely you have a bad sensor, but you should go to a local auto parts store, as most of them, like auto zone, will scan your car for free and tell you what part is most likely bad. a little luck and you will get a cheap fix and pass emissions!

1996 jimmy failed an emission test


Did you change the air filter. The fuel filter will have no impact on emmision's but the air filter is a very common problem.If you usually drive it at low rev.'s then before you send it for emmisions test you will need to put it in a low gear and floor it for about a mile the reason is when it is being tested the engine is reved up to around 3500 rpm and any build up of unburned fuel or oil in the exhaust system will put up the emmisions reading.
