    Crankshaft Position Sensor

    Print

    OPERATION



    The Crankshaft Position (CKP) Sensor is used to monitor engine speed and determines the timing for the for the fuel injectors for each cylinder. On Odyssey models, the CKP sensor is also used to detect an engine misfire.

    The CKP sensor is located in the lower distributor housing on CRV and 1995 Odyssey models. If the CKP sensor in the distributor housing fails, the distributor ignition housing must be replaced.

    On 1996-00 Odyssey models, the CKP sensor is located underneath the lower timing belt cover behind the crankshaft pulley.

    TESTING CRV and 1995 Odyssey Models



    1. With the ignition switch OFF , detach the electrical connector on the side of the distributor housing.
    2.  
    3. Measure the resistance between the following two CKP wires:

      CRV models: The blue and white wires. The resistance should be 300-700 ohms.
       
      1995 Odyssey models: The blue/green and blue/yellow wires. The resistance should be 700-1,300 ohms.
       

    4.  
    5. If the resistance is not in the specified range, replace the distributor ignition housing.
    6.  

    1996-00 Odyssey models

    1. With the ignition switch OFF , detach the electrical connector for the CKP sensor along the lower timing belt cover.
    2.  
    3. Measure the resistance between the two CKP sensor wires:

      1996-97 Odyssey models: 500-1,000 ohms.
       
      1998-00 Odyssey models: 1,850-2,450 ohms.
       

    4.  
    5. If the resistance is not within the specified range, replace CKP sensor.
    6.

    2.  
    3. Remove the distributor cap leaving the wires attached and place aside.
    4.  
    5. Disconnect the electrical connectors at the side of the distributor housing.
    6.  
    7. Make a matchmark reference mark between the distributor housing and the cylinder head and remove the distributor housing assembly.
    8.  

    To install:
    1. Transfer the components not supplied with the replacement distributor housing assembly.
    2.  
    3. Install the distributor housing assembly in the reverse order of removal.

    1996-00 Odyssey Models

    1. Remove the negative battery cable.
    2.  
    3. Detach the CKP sensor electrical connector at the front of the lower timing belt cover.
    4.  
    5. Remove the accessory drive belts. Refer to General Information and Maintenance for specific details on belt removal.
    6.  
    7. Remove the crankshaft pulley. Refer to Engine and Engine Overhaul timing belt replacement for specific details.
    8.  
    9. Remove the lower timing belt cover.
    10.  
    11. Remove the CKP sensor.
    12.  

    The CKP sensor is part of the Top Dead Center (TDC) Sensor on 1996-98 Odyssey models and must be replaced as an unit.

    1. Install the CKP sensor in the reverse order of removal.
    2.
