Camshaft Position Sensor Details For Cadillac?

In this section he details are provided for Camshaft Position Sensor DESCRIPTION & OPERATION.


The camshaft position (CMP) sensor is also a magneto resistive sensor, with the same type of circuits as the crankshaft position (CKP) sensor. The CMP sensor signal is a digital ON/OFF pulse, output once per revolution of the camshaft. The CMP sensor information is used by the PCM to determine the position of the valve train relative to the crankshaft position.

The camshaft reluctor wheel is part of the camshaft sprocket. The reluctor wheel profile is a smooth track, half of which is of a lower profile than the other half. This allows the CMP sensor to supply a signal as soon as the key is turned ON, since the CMP sensor reads the track profile, instead of a notch.

These details will help.

Thanks.

WARNING

Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths.

1. Clean and inspect the sealing surfaces.
2. Inspect the valve cover gaskets for damage. Install new gaskets if necessary.
3. Install the valve cover and bolts and tighten to 89 inch lbs. (10 Nm) in the sequence shown.
4. Reposition the fuel injection supply wiring harness.
5. Install the bracket and bolt.
6. Install the two wire connectors on the bracket.
7. Reposition the radio interference capacitor bracket (if equipped).
8. Connect the upper HO2S electrical connector.
9. Connect the fuel injector electrical connectors.
10. Connect the fuel pressure regulator electrical connector and the vacuum hose.
11. Install the wiring harness retainers on the valve cover studs.
12. Install the breather tube on the valve cover.
13. Install the coil-on-plug assemblies.
    
    NOTE

    Push the coil assemblies down firmly until the boot seal has sealed the access hole.
14. Install the coil assemblies.
15. Install the coil assembly bolts.
16. Connect the ignition coil electrical connectors.
17. Connect the cylinder head temperature (CHT) sensor electrical connector.
18. Position the CHT boot.
19. Connect the camshaft position (CMP) sensor electrical connector.
20. Connect the battery ground cable.
