You need to have it checked with a scan tool to know what codes are setting, it may have nothing to do with the gas cap.
I had it checked with tool 2 times and same code came up. Replaced gas cap and 1 person said it could take me driving it for 100 miles before it went off and another said it should go off right away and it is still on which one is right
It means that your relay is out, and has to be replaced with a new one, and once its been replaced, your check engine light will turn off in about 20 minutes or so.
I had all sensors replaced in my 03 Trailblazer and the check engine light stiil comes on. Why?
A clogged or defective fuel filter will very likely cause a check engine light. If it is suspected, it should be replaced.
check engine light reset on a 1999 Acura CL 3.0.. Just replaced the egr valve. Thx
If a check engine light is appearing when the car starts then the ECU is receiving an alert from somewhere in the engine. The computer should receive a diagnostic test which will provide an answer as to why the check engine light appeared on the 1997 Honda Civic.
Disconnect the battery for about 10-15 minutes resets the computer, and that means no Check Engine Light after you have fixed/ replaced what was wrong.
Is there a reset button on a 1996 rav4? Had it checked out, and said it need spark plugs and wires. Replaced it and check engine light still on.

The head lights have nothing to do with the check engine light.
