  1. My code reader says my oil pressure circuit is high

    Problems and Solutions
    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...
