Crankshaft Position Sensor

Print

Operation



The crankshaft position sensor is a Hall Effect type sensor that senses the crank angle of each cylinder and converts it into a pulse signal. Based on the input signal, the PCM computes the engine speed and controls the fuel injection timing and ignition timing.

Removal & Installation



  1. Disconnect the negative battery cable.
  2.  
  3. Disconnect the connector from the sensor.
  4.  
  5. Remove the retaining bolts.
  6.  
  7. Remove the sensor from its mounting.
  8.  

To install:

  1. Installation is the reverse of the removal procedure.
  2.  
  3. Clearance between the sensor and the sensor wheel should be 0.020-0.059 inch.
  4.  

Testing



2.4L Engine
  1. To check the signal voltage, disconnect the connector.
  2.  
  3. Turn the ignition switch to the ON position.
  4.  
  5. Using terminal 2 and ground check the voltage (harness side of the connector).
  6.  
  7. Voltage specification should be 4.8-5.2 volts.
  8.  
  9. If abnormality is found, replace the sensor.
  10.  

2.7L Engine
  1. To check the signal voltage, disconnect the connector.
  2.  
  3. Turn the ignition switch to the ON position.
  4.  
  5. Using terminal 2 and ground check the voltage (harness side of the connector).
  6.  
  7. Voltage specification should be 4.8-5.2 volts.
  8.  
  9. If abnormality is found, replace the sensor.
  10.  

3.5L Engine
  1. Be sure that the CKPS and PCM connectors are connected.
  2.  
  3. Engine ON and monitor the signal waveform of the sensor on the scan tool. Check whether the waveform is synchronized with the camshaft position sensor or not.
  4.  
  5. If the waveform signal is normal, check the PCM.
  6.  
  7. If the waveform signal is not normal, substitute with a known good CKPS sensor and check for proper operation. If the problem is corrected, replace the CMPS.
