Question about 2002 Saturn Sl

1 Answer

I have a SC1 Saturn - the service engine soon light has come on - I took it to a local garage they put it on the computer and said it may need plugs and wires or sensor of some sort. This morning on my way in it started chugging - it was already warm but I guess the term is "missing" - any ideas of what could be wrong.. It has low mileage and I have never had any problems - rountine maintenance done like clockwork... any ideas ???

Sounds like it could be a bad ignition module
this is what supplies spark to the spark plugs-it is very common on the s series saturns-the bolts that mount it through time stretch out and moisture gathers underneath the module which in turn causes corrosion-then starts to restrict proper spark to the plugs-if the code pulled is a cylinder misfire code(p0300,p0301,p0302,p0303,p0304)i would suggest replacing the module,plugs,wires, and the mounting bolts.
many have tried replacing just coils and usually ends up coming back or not solving problem at all.

could be a body control module that went bad, but should have the service engine soon light investigated.

Have the car scanned by an OBD-II scanner by your local technician or by an auto parts store like Autozone or Advance. Many times they will do it for free.

Be aware that the body control module is separate from the engine computer which OBD-II was designed to scan.

1993 Saturn SC1 cooling fan doesn't turn on


Two things to check. The fan relay, and the coolant temperature sensor. There may be two sensors, the two wire one is for the computer hence for the ran relay. Buy a haines manual at your local auto parts store. This will help you find what you are looking for, and its only about 15 bucks.

Alternatively you can put a jumper accrss the fan relay to make the fan run whenever the engine is running.
