VNE 9436070 Crankshaft Position Sensor

The VNE 9436070 crankshaft position sensor (also called a crank position sensor or crank sensor) is an engine management part. It monitors the position and rotational speed of the crankshaft and sends that signal to the engine control unit.

The engine computer uses this signal to time ignition and fuel delivery. A worn or failing crankshaft sensor can cause hard starting, stalling or a no-start condition, so replacing it restores accurate engine timing data.
