Crankshaft Position Sensor (CKP)


2.0L ABA Engine

The crankshaft position sensor, unique to the ABA engine, is located on the side of the engine block. A special toothed wheel mounted on the crankshaft works together with the sensor to provide the ECM with information regarding the rotational speed of the crankshaft.

If the Crankshaft Position (CKP) Sensor fails, the engine will not generate a spark and will not start.

The Crankshaft Position Sensor is an essential input for the ECM to determine ignition timing. For additional information, please refer to the following topic(s): Electronic Engine Controls, Crankshaft Position Sensor
