A car wash fouled up my MAF sensor today, so I cleaned it, hooked up a code reader to clear the engine, and all was well. However, it told me I have a P0523 (oil pressure sender voltage too high), a code that apparently doesn't light up the check-engine light.

I'll get under the car tomorrow and make sure no wires are frayed. Can anyone tell me where it is and what to look for? And if it is bad, how can I remove the oil pressure sender?
