    Crankshaft Position Sensor

    Crankshaft Position Sensor Operation:

    A magnetic or hall effect sensor that provides the computer with the engine speed and crankshaft position so proper injector sequence and ignition spark can be determined. It allows the ECC (engine control computer) to change injector openings as the engine RPM changes. It also signals the coil packs to fire the spark plugs.

    How To Instructions:

    Inspect - Check for obvious problems.
    Test - Give it an in-depth diagnosis.
    Service - Do the jobs that fix your car.
    Replace - Out with the old, in with the new.
