Question about 1996 Chevrolet Cavalier

1 Answer

Check engine light and ets light come on and off on 96 cavalier

The check engine light and ets light will come on and stay on for about 75 miles. They will both go off and maybe stay off for 50 miles. The lights come on and off intermittently. I had a code check done at Autozone and a code 440 was detected. I had a new gas cap put on but that doesn't seem to fix the problem. Can anyone assist?

    My '96 Sunfire does the exact same thing. They will stay off for maybe 200 miles and then suddenly come back on for 50 miles, then back off again. I took it to a shop, and when I started it up to pull it into the garage, the light had gone off again! Is it just the light that has a problem perhaps?

    My problem is similar to what is describe here, only it is for a 1997 Caviler. I started about two weeks and stays on all the time... I just realized that about a month ago I lost the fuel cap and never replaced it so I will go and get this done and see if this will resolve the problem.

You need to find out what fault caused the check engine light to come on, until the fault code is retrieved from the engine control module memory you are 100% guessing. I think you have a misfire.

As a rule it takes about 50 miles for the computer to finish it's readiness tests. Some take longer so I would drive it about 75 miles and then check.

2007 Dodge Caliber check engine light stays on......was very low on oil but replenished more then 50 miles ago. no problem with engine how to turn off?

Most times, once your car posts a trouble code you need a OBD-II code reader to pull the code and reset the check engine light. You can get one pretty cheaply from your neighborhood auto parts store. However, some parts stores have one available that they will let you borrow for a small fee or even for free. It connects to a diagnostic port just under the driver's side dash. Dealers and repair shops will typically charge you $50-75 to read the code and reset the light.

How do i turn my check engine light off. It stays

Try disconnecting th ebattery for three minutes and reconnecting it. The light should be off. If there is a problem it will come back on within 50-75 miles. If the battery trick doesn't work go to a repair shop and have them reset the light with the machine.
