Circuit Description

The crankshaft position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor circuits are connected directly to the engine control module (ECM) and consists of the following circuits:

• The 12-volt reference circuit
• The low reference circuit
• The CKP sensor signal circuit

If the ECM detects that there is no signal from the CKP sensor for 3 seconds, DTC P0335 sets.
