P0336

Diagnostic Chart:

Wiring Diagram:

The crankshaft position (CKP) sensor defines engine position by generating an electrical pulse each time it passes by a notch of the crankshaft reluctor wheel. The PCM uses crankshaft sensor pulses for fuel delivery and spark timing.

DTC PARAMETERS

DTC P0336 will set if extra or missing crankshaft sensor pulses are detected or time between reference pulses is too long or too short when:

^ RPM is over 3600 rpm or under 2600 rpm.

^ Engine run time is greater than 10 seconds.

^ ECT is greater than 65°C (149°F).

^ TP is greater than 9.8% open.

^ No ECT TP or P0125 DTCs have been set.

NOTE: The CKP signal is continuously checked after the above conditions have been met.

DIAGNOSTIC AIDS

When attempting to diagnose an intermittent problem use the Scan tool to review malfunction history diagnostic information. The supplemental data can be used to duplicate a problem.

Intermittents or opens suspected to be at the connector can be detected by using diagnostic service probe Voltage can be read on wires without disconnecting any connectors.

Check the tightness of the female terminal grip with a spare male terminal.

Verify that the secondary leads are not in close proximity to the signal wires (IC, REF, etc.).

NOTE: Make sure the crankshaft position sensor circuit wires are clear of other voltage interfering wires. EMI (electromotive interference) waves may offset a crank signal to the PCM, thus setting a DTC.
