Pinpoint Test V: Camshaft Position (CMP) Sensor: Introduction: Detection/Management
An inactive CMP signal during cranking is detectable by the PCM. An inactive CMP signal causes a no-start condition. Electrical noise can also be detected by the PCM. If the level is sufficient to affect engine operation, a corresponding DTC is set.
CAUTION:
The PCM harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no-start condition. Installing PCM connectors on an angle may cause an improper connection, misdiagnosis, and damaged components. Install the connector until the lever pivots and seats itself. Apply light pressure to get the connector into position on the PCM and then fully seat the connector.
NOTE:
Visually inspect the harness connectors for corrosion, damage, proper mating, and correct pin tension.
