DTC P0336 Crankshaft Position (CKP) Sensor Performance

Circuit Description

The crankshaft position (CKP) sensor is located on the flywheel housing. The sensor rotor is fixed on the flywheel. There

are 56 notches spaced 6° apart and a 30° section that is open span. This open span portion allows for the detection of top dead center (TDC). The ECM monitors both CKP sensor and camshaft position (CMP) sensor signal pulses to ensure they correlate with each other. If the ECM receives extra or missing CKP sensor signal pulse this DTC will set.

Condition for Running the DTC

^ DTCs P0335 P0340 P0642 P0643 P0652 and P0653 are not set.
^ The battery voltage is between 10 to 16 volts.
^ The ignition switch is ON.
^ The CKP sensor signal pulse is detected.

Condition for Setting the DTC

^ The ECM detects extra or missing CKP sensor signal pulses during engine 50 rotations.

Action Taken When the DTC Sets

^ The ECM illuminates the MIL when the diagnostic runs and fails. Refer to DTC Type Definitions for Action Taken When the DTC Sets - Type A.
^ The ECM limits fuel injection quantity.
^ The ECM inhibits EGR control.
^ The ECM inhibits DPF regeneration control.
^ The ECM inhibits cruise control.

Condition for Clearing the DTC

^ Refer to DTC Type Definitions for Condition for Clearing the MIL/DTC - Type A.

Diagnostic Aids

^ If an intermittent condition is suspected refer to Intermittent Conditions in this section.
- Electromagnetic interference in the CKP sensor circuits may set this DTC.
^ An intermittent CKP sensor signal pulse may set this DTC.
^ Ensure the sensor is tight and the sensor rotor teeth are not damaged.
