Circuit Description

The circuit uses 2 different types of Crankshaft Position (CKP) sensors. The CKP sensor "B" is connected directly to the Ignition Control Module (ICM), and consists of the CKP 1 sensor signal circuit and the low reference circuit.

The CKP sensor "A" connects directly to the Powertrain Control Module (PCM), and consists of the 12-volt reference circuit, the medium resolution engine speed signal circuit and the low reference circuit If PCM detects an incorrect number of CKP pulses, DTC P0336 sets.
