Service Maintenance light on the dash

Hi, Any ideas as to what sensor would trigger this? Engine is running ok, I haven't changed the oil in awhile. No smoke out the tail pipe. Oil level is good.

Would the water pump have seized?

Model SL1 year 93

Thanks

Could be as simple as the gas cap is not on tight.

You said the engine is running well. In my opinion, this rules out the water pump having seized. (Not sure what led you to that potential root cause...) No smoke out the tail pipe is another good thing. Changing oil regularly is excellent preventive maintenance for your engine, but again, not related in any way to the check engine light being on.

The only thing you know for certain is that the engine computer has determined there is a problem. This is based on the information it received (or did not receive) from the various feedback sensors used to determine overall health of the system. You really need to know the error code that was set to provide insight into which sensor provided the bad data and set the fault condition. If you are in the US, Autozone reads the OBD_II error codes for free and can tell you the cause. Post the error code and description once you have it and you are likely to get some useful direction on what to check from this group.

Also post vehicle mileage, maintenance history, and all other symptoms you are seeing (starts hard, poor acceleration, rough idle after warms up, poor mileage, overheating, alternator light on, etc.)

I have the same situation.

1993 Saturn SL 4 Door Engine Light Comes On and Off Engine Oil Level ok Fan Belt seems to be a bit loose, making low noise? No visible smoke or such problem from tailpipe Error Code 12 from OBD

Any idea what this error code means?

After checking Steve and Bob's suggestions and if your codes show the same, etc - it could be an EGR Valve - had similar thing happening with my '98 Saturn - replaced EGR Valve and all was good then.

Please DO go to Autozone for the free check. My daughter has a '03 Mitsubishi that had the "Check Engine" light come on and was due for an oil change anyway. Had I known this I would've told her about Autozone. The Mitsubishi dealer did the check (in less than 5 minutes) and it was a simple "History" fault that actually wasn't a problem. They reset it and charged $90 for one hour of diagnostic service. So after sales tax, she basically paid nearly $130 for an oil change.

Most distressing. Many of us are busy beavers, and don't have the time to wrestle with the gougers that give the rest of the industry a bad name.

I'm in Canada, and don't have access to "Autozone" for a free OBD reading. I'll need to negotiate a price with a local shop somewhere. Certainly won't be a dealership. I'll post the code later.
