I have a Buick Regal LS and I had them run a computer diagnosis and it was due to the gas cap not fitting properly. There is an electronic sensor there. Most automotive stores will do this check for you free of charge.
how do you reset check engine light in 2008 buick lucerne
engine light
The check engine light on a Buick Regal can be reset with a special diagnostic scanner. This can be performed at a car dealership or service garage.
The check engine light on the 1998 Buick Park Avenue can be reset by disconnecting the battery for a few minutes and then reconnecting it. The check engine light is only going to stay off if the problem that created the light is fixed.
It looks like an engine, or it may just say Check Engine.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
Get a code read out from your engine computer and it will tell you what is wrong.
If the check engine light does not flash when in the diag mode, the problem is the computer. Could be as simple as a failed lamp driver but a failed computer is toast and will need to be replaced/
If the check engine light is on then have it scanned for codes. I could guess you into bankruptsy. It is cheaper to have it scanned and repaired.
the sensor is going out
