P0336

CIRCUIT DESCRIPTION
The Crankshaft Position (CKP) sensor is connected directly to the Ignition Control (IC) module. The CKP sensor consists of the following circuits:
^ The 10-volt reference circuit
^ The low reference circuit
^ The CKP sensor 1 signal circuit
^ The CKP sensor 2 signal circuit

The CKP sensor shares power supply and low reference circuits with the Camshaft Position (CMP) sensor.

CONDITIONS FOR RUNNING THE DTC
The engine is running, and 3X reference pulses are being received.

CONDITIONS FOR SETTING THE DTC
The 18X reference pulses are not received in 1 engine cycle, at 720 degrees of crankshaft rotation.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The control module turns OFF the Malfunction Indicator Lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
^ A current DTC "Last Test Failed" clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
^ Use a scan tool in order to clear the MIL and the DTC.

DIAGNOSTIC AIDS
Inspect for the following conditions:
^ Incorrect harness routing near secondary ignition components.
^ Faulty ignition coil-Remove the ignition coils and inspect the ignition control module and coils for cracks, for carbon tracking, or for other signs that indicate that the coil secondary circuit is arcing to the ICM or to the ICM wiring harness. Refer to Ignition Coil(s) Replacement
^ Secondary ignition wires arcing to wiring harness-Inspect the secondary ignition wires for carbon tracking or for other signs of damage.
^ Poor Connections-Refer to Testing for Intermittent and Poor Connections in Diagrams.
