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 the CKP sensor signal is inconsistent, DTC P0336 sets.
