P0016-CRANKSHAFT / CAMSHAFT TIMING MISALIGNMENT





For complete wiring diagrams refer to Diagrams/Electrical.


- When Monitored:

With the engine speed between 480 and 6816 RPM and no CMP or CKP sensor DTCs detected.

- Set Condition:

Powertrain Control Module detects an error when the camshaft position is out of phase with the crankshaft position. One Trip Fault. Three good trips to turn off the MIL.







Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

- Go To 9

No

- Go To 8

8. CRANKSHAFT POSITION SENSOR IRREGULAR SIGNAL

Turn the ignition off.

Using a lab scope and the Miller special tool #6801, backprobe the (K24) CKP Signal circuit in the Crankshaft Position Sensor harness connector.

Turn the ignition on.

Wiggle the related wire harness and lightly tap on the Crankshaft Position Sensor while monitoring the lab scope screen.

Start the engine.


WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.

Monitor the Crankshaft Position Sensor signal on the lab scope screen.

Were any Crankshaft Position Sensor signals irregular or missing?
