Camshaft Position (CMP) Sensor

Removal

1. Disconnect battery ground cable (14301) .

2. Disconnect fuel charging wiring (9D930) from camshaft position sensor (CMP sensor) (12126) .

3. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing.

4. If camshaft position sensor housing is to be removed from the engine front cover (6019) proceed with Removal Step 5. If camshaft position sensor housing is not being removed, proceed to Installation Step 6.
   
   
   
   

    CAUTION: Before proceeding with this procedure, set cylinder No. 1 to 26 degrees After Top Dead Center (ATDC) of the compression stroke. Then note the position of the camshaft position sensor electrical connector. The installation procedure requires that the connector be located in the same position.

5. Remove hold-down clamp (12270) (bolt and washer).

   NOTE: The oil pump intermediate shaft (6A618) should be removed with the camshaft position sensor housing.

6. Remove camshaft position sensor housing from engine front cover .

Installation

 CAUTION: If the replacement camshaft position sensor does not contain a plastic locator cover tool, a special service tool such as Syncro Positioner Tool T89P-12200-A must be obtained prior to installation of the replacement camshaft position sensor . Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.

1. If the plastic locator cover tool is not attached to the replacement camshaft position sensor , attach Syncro Positioner Tool T89P-12200-A as follows:
   1. Engage camshaft position sensor housing vane into the radial slot of the tool.
   2. Rotate tool on camshaft position sensor housing until tool boss engages notch in camshaft position sensor housing. The cover tool should be square and in contact with entire top surface of camshaft position sensor housing.

2. Transfer oil pump intermediate shaft from old camshaft position sensor housing to replacement camshaft position sensor housing.

    CAUTION: If camshaft position sensor electrical connector is not positioned properly (i.e. contacting the A/C compressor bracket), DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1.

3. Install camshaft position sensor housing so that drive gear engagement occurs when arrow on locator tool is pointed approximately 30 degrees counterclockwise from the front face of the cylinder block (6010) . This step will locate camshaft position sensor electrical connector in the pre-removal position.

4. Install hold-down clamp (washer and bolt) and tighten bolt to 20-30 Nm (15-22 lb-ft).

5. Remove Syncro Positioner Tool T89P-12200-A.

    CAUTION: If camshaft position sensor electrical connector is not positioned properly (i.e. contacting the A/C compressor bracket), DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1.

6. Install camshaft position sensor and retaining screws. Tighten screws to 2.5-3.5 Nm (22-31 lb-in).

7. Connect fuel charging wiring connector to camshaft position sensor .

8. Connect battery ground cable .
