Question about Oldsmobile Alero
I just bought the car. it only has 17400k on it.seems to be in great shape,was owned by a older woman who i've known for several years.just started driving today and the service eng. soon lite came on and stays on steady (not flashing)put a new gas cap on,the gasket was dry and cracked,the lite is still on 20mi later?
Try resetting the computer. Disconnect your battery for 5-10 minutes and reconnect. This should get rid of the light if the gas cap was the problem. If it comes back on take it to an Advanced Auto or Auto zone and get an Engine Diagnostic, they're free. Hope this helps

When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
