P0016

DTC P0016

CIRCUIT DESCRIPTION
The engine control module (ECM) uses the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor signals to monitor the correlation between the crankshaft and camshaft positions. If the ECM detects that the timing between the crankshaft and the camshaft is incorrect, DTC P0016 sets.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC P0016 Crankshaft Position (CKP) Camshaft Position (CMP) Correlation

CONDITIONS FOR RUNNING THE DTC
- The engine is cranking, or the engine is running.
- DTCs P0335, P0336, P0340, P0341 are not set.
- DTC P0016 runs continuously when the above conditions are met.

CONDITIONS FOR SETTING THE DTC
The ECM detects that the timing between the crankshaft and the camshaft is incorrect for one cam trigger pulse.

ACTION TAKEN WHEN THE DTC SETS
- The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The control module stores the information in the Freeze Frame/Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
- The control module turns OFF the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC last test failed clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles if no failures are reported by this or any other emission related diagnostic.

TEST DESCRIPTION

Step 1 - Step 7:

The number below refers to the step number on the diagnostic table.
5. An incorrectly installed camshaft gear, crankshaft sprocket, or timing chain can cause this DTC to set.
