Pinpoint Test Q: DTC P0335, P0336; CRANKSHAFT POSITION (CKP) SENSOR CIRCUIT RANGE/PERFORMANCE, CIRCUIT MALFUNCTION

NOTE: The clearance between the CKP sensor and the reluctor ring should be checked at 90° intervals. The air gap between the two should be no greater than 4.5 mm at any point.
  1. CHECK THE CKP SENSOR FOR CORRECT INSTALLATION 

    Turn the ignition switch to the OFF position.

    Check the CKP sensor for correct installation.

    Is the CKP sensor correctly installed? 

    YES:  Go to step  2.

    NO:  INSTALL the CKP sensor correctly. Refer to Crankshaft Position (CKP) Sensor . Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

  2. CHECK THE CKP SENSOR FOR DEBRIS 

    Remove the CKP sensor and inspect for debris.

    Is the CKP sensor free of debris? 

    YES:  Go to step  3.

    NO:  CLEAN the sensor and wheel. INSTALL the sensor. Refer to Crankshaft Position (CKP) Sensor . Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

  3. CHECK THE CKP SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE 

    Disconnect the battery negative terminal.

    Disconnect the ECM electrical connector, EM80.

    Disconnect the CKP sensor electrical connector, PI17.

    Measure the resistance between PI17, pin 02 (Y) and EM80, pin 36 (Y).

    Is the resistance greater than 5 ohms? 

    YES:  REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

    NO:  Go to step  4.

  4. CHECK THE CKP SENSOR SENSING CIRCUIT FOR SHORT TO HIGH VOLTAGE 

    Reconnect the battery negative terminal.

    Turn the ignition switch to the ON position.

    Measure the voltage between PI17, pin 02 (Y) and GROUND.

    Is the voltage greater than 3 volts? 

    YES:  REPAIR the short circuit to high voltage. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

    NO:  Go to step  5.

  5. CHECK THE CKP SENSOR SENSING CIRCUIT FOR SHORT TO GROUND 

    Turn the ignition switch to the OFF position.

    Measure the resistance between PI17, pin 02 (Y) and GROUND.

    Is the resistance less than 10,000 ohms? 

    YES:  REPAIR the short circuit to GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

    NO:  Go to step  6.

  6. CHECK THE CKP SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE 

    Measure the resistance between PI17, pin 01 (P) and EM80, pin 37 (P).

    Is the resistance greater than 5 ohms? 

    YES:  REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

    NO:  INSTALL a new CKP sensor. Refer to Crankshaft Position (CKP) Sensor . CLEAR the DTC. TEST the system for normal operation.
