Camshaft Position Actuator Magnet Cleaning and Inspection
WARNING: This page is about a different variant/trim than selected.
- Inspect the CMP magnet for the following conditions:
- A damaged electrical connector
- An accumulation of dirt or debris in the recessed area around the pintle
- A build-up of burnt engine oil on the shaft of the pintle which may cause the pintle to stick and not move freely within the proper range of travel
- Holding the CMP magnet with the pintle facing upward, measure the pintle retracted position (a). Record the dimension.
- Holding the CMP magnet with the pintle facing downward, measure the pintle extended position (a). Record the dimension.
- Subtract the retracted dimension from the extended dimension to determine pintle travel. A properly moving pintle will travel 3.0-5.5 mm (0.12-0.22 in).
- If the pintle of the CMP magnet is binding or does not move within the proper range of travel, replace the CMP magnet as an assembly.
IMPORTANT:
If checking the operating range of the CMP magnet pintle, DO NOT energize the magnet with a 12V power supply. Use steps 2 thru 5 below to check pintle operating range. To dynamically test the magnet pintle with a power supply, refer to the dynamic test instructions listed under the component testing portion of DTC P0011. Refer to DTC P0011
