Print

Removal & Installation



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

To install:

  1. Installation is the reverse of the removal procedure.
  2.  

Description & Operation



The camshaft position sensor senses the TDC point of the number one cylinder, on its compression stroke. Its signal is relayed to the ECM to be used to determine the sequence of fuel injection.

Testing



2.7L Engine
  1. Connect the scan tool to the data link connector.
  2.  
  3. Start the engine and let it idle.
  4.  
  5. Monitor -CKP T/WHEELS-LO CMP- and -CKP T/WHEELS-HI CMP- parameters on the scan tool data list.
  6.  
  7. Specification should be -CKP T/WHEELS-LO CMP-: 38 plus/minus 4 tooth, and -CKP T/WHEELS-HI CMP-: 98 plus/minus 4 tooth.
  8.  
  9. If specification is normal, check for poor connection between the ECM and the components.
  10.  
  11. If specification is not normal, remove the sensor and calculate the air gap.
  12.  
  13. Check the sensor for contamination, deterioration or damage.
  14.  
  15. Substitute the sensor with a known good component, check for proper operation. If problem corrected replace the sensor.
  16.  

2.0L Engine
  1. Be sure that the CMPS and PCM connectors are connected.
  2.  
  3. Set up an oscilloscope as follows: Channel A (+): terminal 2 of the CKPS, (-): ground. Channel B (+): terminal 2 of the CMPS, (-): ground.
  4.  
  5. Start the engine and check for signal waveform (whether synchronize with crankshaft sensor or not and tooth is missing).
  6.  
  7. Readings are as follows: The square wave signal should be smooth and without distortion.
  8.  
  9. Readings are as follows: The CMPS falling (rising) edge should coincide with 3-5 tooth of the CKP from one longer signal (missing tooth).
  10.  
  11. If the waveform signal is normal, check for poor connection between the PCM and the components.
  12.  
  13. If the waveform signal is not normal, remove the sensor and calculate the air gap between the sensor and the flywheel/torque converter.
  14.  
  15. Air gap is 0.07 inch. Measure from the distance of the housing to teeth on the flywheel/torque converter (measurement -A-) and from the mounting surface on the sensor to sensor tip (measurement -B-), then subtract -B- from -A-.
  16.  
  17. Check the sensor for contamination, deterioration or damage.
  18.  
  19. Substitute the sensor with a known good component, check for proper operation. If problem corrected replace the sensor.
