Diagnostic Aids
An inactive CMP signal during cranking is detectable by PCM and will cause a no-start condition. Electrical noise can also be detected by PCM and if noise level effects engine operation, a corresponding DTC will be set. Perform this test when directed by QUICK TEST. This test is only intended to diagnose the following components and circuits:
- Camshaft Position (CMP) Sensor
- Wiring Harness Circuits; (CMP, CMP GND & VREF)
- Powertrain Control Module (PCM)
