Full Answer

As part of an engine monitoring system, the crankshaft sensor is essential in supplying the RPM signal to the vehicle's dashboard. Excessive heat can damage crankshaft sensors. A malfunctioning sensor can lead to the vehicle stalling or not being able to start at all.

A crankshaft sensor works in conjunction with a camshaft sensor in order to establish the proper injector synchronization and coil firing sequence for the vehicle.

    What causes engine backfire?

    A:

    Engine backfire is caused by an imbalance in the air-to-fuel ratio of the vehicle. Backfires occur in one of two places. A backfire in the intake manifold is caused by a ratio that is too lean (not enough fuel). A backfire out of the exhaust system is caused by a ratio that is too rich (too much fuel).
