Important: Do not energize the camshaft position (CMP) magnet using a 12-volt power supply.
- 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.
