DTC P0336: Crankshaft Position Sensor Performance: Description
WARNING: This page is about a different car, the 2003 Pontiac Sunfire, 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The Crankshaft Position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor produces an AC voltage of different amplitude and frequency, depending on the velocity of the crankshaft. The CKP sensor is connected directly to the Powertrain Control Module (PCM). The circuits between the CKP sensor and the PCM consist of the following circuits: The CKP sensor 1 signal circuit and low reference circuit. If the PCM detects an incorrect number of CKP pulses, DTC P0336 sets.
