Crankshaft Position Sensor

Print

Operation



A 5-volt voltage is applied on the Crankshaft Position (CKP) Sensor output terminal from the ECM/PCM. The sensor generates a pulse signal when the output terminal is opened and grounded.

Removal & Installation



  1. Disconnect the negative battery cable.
  2.  
  3. Detach the crankshaft position sensor electrical connector.
  4.  
  5. Unfasten the retaining bolt, then remove the sensor.
  6.  

To install:

  1. Position the sensor and install the retaining bolt.
  2.  
  3. Attach the crankshaft position sensor electrical connector.
  4.  
  5. Connect the negative battery cable.

Testing



  1. Disconnect the sensor connector and measure at the harness side.
  2.  
  3. Turn the ignition switch to the "ON" position.
  4.  
  5. Measure the voltage between terminal No. 2 and ground. Voltage should be between 4.8 and 5.2 volts.
  6.  
  7. Turn the ignition switch to the "LOCK" (OFF) position.
  8.  
  9. If not within specifications, check connectors and wiring between the sensor and ECM/PCM. Repair/replace as necessary.
  10.  
  11. If within specifications, disconnect the sensor connector and measure at the harness side.
  12.  
  13. Turn the ignition switch to the "ON" position.
  14.  
  15. Measure the voltage between terminal No. 3 and ground. Voltage should be battery positive voltage.
  16.  
  17. Turn the ignition switch to the "LOCK" (OFF) position.
  18.  
  19. If not within specifications, check connectors and wiring between the sensor and MFI relay. Repair/replace as necessary.
  20.  
  21. If within specifications, disconnect the sensor connector and measure at the harness side.
  22.  
  23. Check for the resistance between terminal No. 1 and ground. Resistance should be less than 2 ohms.
  24.  
  25. If not within specifications, check connectors and wiring between the sensor and ECM/PCM. If connectors and wiring between sensor and ECM/PCM are good, replace the ECM/PCM.
  26.  
  27. If within specifications, check the CKP sensor-sensing blade.
  28.  
  29. If the sensor-sensing blade is damaged, replace it.
  30.  
  31. If the sensor-sensing blade is good, replace the CKP sensor.
