Crankshaft Sensor Failure

Information

What does a crankshaft sensor do?

Usually mounted in the engine block or positioned at the bottom of the timing gear cover, and a vital part of the electronics of a vehicle, a crankshaft sensor controls the ignition switch timing and monitors the position or rotational speed of the crankshaft.

How can I tell if something is wrong with the crankshaft sensor?

The malfunction of this component can cause a vehicle to be hard to start or misfire. It’s easy to mistakenly replace spark plugs, or even a fuel pump, for a bad crankshaft sensor. Since many newer vehicles store trouble codes in the car’s computer system, crankshaft sensor failures are now easier to identify through diagnostic equipment.

What are my options?

The vehicle may need to be taken to an auto repair shop to perform diagnostics. Numerous automotive websites advertise diagnostic and repair services. Other vendors sell service manuals and how-to books.
