Is your gas cap tight? check it, these codes indicate a large leak in the fuel evaporative emission recovery system at the gas tank

First thing you have to do is list all the codes, because some some might be stored for a long time. Pushing the OFF and WARM buttons together and holding will ghive you all the stored codes. Then press OFF and HI together to clear all codes. Hold and wait for bars or 0's. Now start your car and let it get up to proper operating temps. Take car for aride that aincludes all phases of driving including highway speeds. Observe SERVICE ENGINE LIGHT for coming on . Assuming it does , repeat steps previously provided, read codes stored and repair accordingly. If need be contact me with new codes and I will try to assist you.

I would try replacing the Oxygen sensor, then clear the code.

The O2 sensor would be the after the catalytic converter ( sensor 2) on the exhaust pipe of the number 2 cylinder uses ( bank 2).

How to reset the check engine light on a 2005 Cadillac STS V8?


If the check engine light is on, there is a problem that the computer has detected and it needs to be fixed first. Once the proper repair(s) have been made you can use a code reader that has the ability to "reset" the light. You could also just disconnect the battery for 15 minutes. If the problem hasen't been fixed the light will come back on.

Check service light not coming on before starting engine, guy at smog shop say he needs to see the light


Thanks for choosing FixYa and welcome. When the light is on, you can test the computer and find out what is wrong with your vehicle. As soon as it comes on, take it to Autozone to have it scanned. It is free there and then you can tell you shop guy the code you have got.

The "service engine soon" light


Generally is yes, "check engine" are refer to the emission codes, but not always. I suggest visit some autozone ot autoshop with scan tools or "reader code" to know exactly what fault code is stored there. With this code number we could send you additional details.

Keep in touch.

2001 Cadillac Sts: engine will die while idoling and sometimes while im driving...it also bogs down when driving and the service engine light will appear and b4 i can get it checked the light goes...


First item that I would check is the idle control valve. you can increase the idle speed of your engine if it runs below normal. Since you get a check engine light, I would suggest to get the error code.
