Circuit Description

The crankshaft position (CKP) sensor is a variable reluctance sensor. The CKP sensor indicates the crankshaft speed and position. The CKP sensor produces an AC voltage of different amplitude and frequency. The frequency depends on the velocity of the crankshaft. The AC voltage output depends on the crankshaft position and the battery voltage. The CKP sensor connects to the engine control module (ECM) through the following circuits:

• The CKP sensor signal circuit
• The low reference circuit

If the ECM detects an excessive number of resyncs from the CKP sensor, DTC P0336 sets.
