I have 2 service engine lights on my 2002 buick lasabre. Both are yellow lights. I can reset the top one but not the bottom one.


If you have a warning light, that means there's a trouble code stored in the computer. Getting the trouble code read is always the first step in diagnosing a problem. Guessing without codes is a bad way to go.

What is trouble code 41 for 1988 olds 98???


It indicates a problem with the cam sensor. The problem could be a defective cam sensor or it could also be the magnet attached to the cam gear that the sensor detects. They have a history of falling off after many heating and cooling cycles. If the magnet (about the size of a dime) is missing, replacing the cam sensor won't help. The magnet will need to be replaced.

this code is indicated the cam signal was lost, however the engine will run with a simultainous mode.
you need to check to see if this vehicle equipted with an anti-thief system. look on the instrument cluster to see if the theft light is there, also if the key has a chip on it.
if there is then you need to look in to the vehicle security system

Check engine lights came on.


Yes an OBD 1 meter will give you a better idea as to what the problem is,however it would be more cost effective to find an OBD 2 meter with the capability to test OBD 1 cars.I do have the same problem with my 88 Lasabre,the 3 codes coming up would be the cam shaft sensor($20),the ignition mudule ($140),or the ECM ($80),I found that on mine the number 3 cylinder does not look like it is firing when I inspect the spark plug,but the only code I get # 41.I'am going to start with the cheapest part first.If you have a basic understanding of the mechanics of vehicles(or a haynes repair manual) you could probably replace this yourself.If you already found the solution to this problem please email me at mikehitchner@comcast.net so that I can fix mine.Thanks

Service engine soon light comes on and goes off


The service engine soon light comes on for many reasons..it could be as simple as CO2 sensor, or it may just be one of the lights that just stays on, ask your local GM garagre to reset the code for you..maybe cost you a couple bucks.
