Circuit Description
WARNING: This page is about a different variant/trim than selected.
The crankshaft position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor works in conjunction with a 58-rib reluctor ring attached to the crankshaft in which two ribs are missing, 60 minus 2 ring. The engine control module (ECM) synchronizes the crankshaft position by the reference gap which is created by the two missing ribs. The CKP sensor circuits are connected directly to the ECM. The circuits between the CKP sensor and the ECM consists of the following:
- A CKP sensor high
- A CKP sensor low
- A shielded ground
If the ECM has detected less than 58 reference pulses, DTC P0337 sets.
