DTC P0336: Crankshaft Position Sensor Performance: Description
WARNING: This page is about a different car, the 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, 2003 Chevrolet Monte Carlo, and 2003 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
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 following circuits:
- The CKP sensor 1 signal circuit.
- The low reference circuit.
The CKP sensor A connects directly to the Powertrain Control Module (PCM), and consists of the following circuits:
- The 12-volt reference circuit.
- The medium resolution engine speed signal circuit.
- The low reference circuit.
If the PCM detects an incorrect number of CKP pulses, DTC P0336 sets.
