DTC P0336: Crankshaft Position Sensor Circuit: Description

WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The Crankshaft Position (CKP) sensor produces an AC voltage of different amplitude and frequency depending on the velocity of the crankshaft. This AC voltage signal is fed into the ECM. The crankshaft has 7 total machined notches, 6 of which are spaced 60 degrees apart. The remaining tooth is 10 degrees before the No. 4 cylinder TDC notch. This extra notch is used by the ECM to determine the position of the top dead center No. 4 cylinder necessary to synchronize engine position. The CKP sensor is used for fuel delivery, spark timing and misfire diagnostics. DTC P0336 sets when the number of pulses or time between pulses is not valid.
