Engine Mechanical problem
1996 Saturn SC2 4 cyl Front Wheel Drive Manual 149, xx miles

I just bought this car, and the check engine light has been on I scanned it and it's that map sensor code, and I replace the sensor and check the vaccum holes and intake, and for the life of me I can't figure out the problem. I'm to the point of taking it in and paying to get it fixed, which I never do. Can help at all? Could it be because of a value cover gasket leak? When you pull the plug wire and look down in there, there is oil, the guy before me said he changed the gasket but clear he didn't do it right, could that have anything to do with the code? I really need your help here, thank you.

Your map or tps reading are stuck out of range that's what that code mean's your going to have figure out which one.Then you have to figure why the sensor or the wiring.

All you need is a scanner that can display live engine data so you can look at what your map and tps is reading and compare that to what they have for value's.

If the reading's act up while your driving the car could die and leave you stranded possibly in the middle of traffic. So I say drive at your own risk.I would fix it as soon as you can. Since you already replaced the map sensor which those hardly ever fail.I would say your left with a bad tps which hardly ever fail's or the wiring going from the tps or map sensors. If you had a scan tool to monitor the sensor's key on engine off you might be able to just move the wire's around in the engine compartment and find the problem that way.

Yes I say it's probably wiring but without being able to see what those sensor's are reading it's going to be pretty hard to figure out. Also those wire's run from the sensor's to the pcm inside the car. So it's going to be hard to shotgun unless you want to rewire both sensor's all the way to the pcm and change the tps and if that doesn't work you would have to trouble shoot the pcm. The scanner's have gotten alot cheaper they end up paying for themselves in the long run or sometimes the short run. But entirely up to you how you want to fix it.I'm just here to help people.
