Crankshaft Position Sensor for 4-cylinder petrol applications – 1.8L K Series and 2.0L MPi T Series – mounted at the crankshaft in the engine block assembly group.

The sensor reads the toothed reluctor ring on the crankshaft and supplies engine speed and crank angle data to the engine control module, which uses it to time ignition and fuel injection.

A degraded signal typically presents as a non-start, an intermittent cut-out, or an erratic tachometer reading.
