P0016

DTC P0016

Circuit Description

The powertrain control module (PCM) 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 PCM 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

* DTCs P0335, P0336, P0340, P0341, P0385, P0386 are not set.
* The diagnostic runs continuously when the above condition is met.

Conditions for Setting the DTC

The PCM detects that the timing between the crankshaft and the camshaft is incorrect for less than 1 second.

Action Taken When the DTC Sets

* The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
* The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

Conditions for Clearing the MIL/DTC

* The control module turns OFF the malfunction indicator lamp (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.
* Clear the MIL and the DTC with a scan tool.

Diagnostic Aids

Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, crankshaft, or timing chain can cause this DTC to set.

Test Description

Step 1 - Step 7:

The numbers below refer to the step numbers on the diagnostic table.
2. This step determines if a condition is present.
5. This step inspects for any recent engine mechanical repairs. An incorrectly installed camshaft, crankshaft or timing chain can cause this DTC to set.
