DTC P0336: Crankshaft Position Sensor Circuit: Description
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 PCM. The crankshaft has 7 total machined notches, 6 of which are spaced 60 degrees apart. The remaining tooth is 10 degrees before the #4 cylinder TDC notch. This extra notch is used by the PCM to determine the position of the top dead center #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.
