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.
