DTC P0016 or P0017
Diagnostic Instructions
DTC Descriptors
DTC P0016: Crankshaft Position - Inlet Camshaft Position Not Plausible
DTC P0017: Crankshaft Position - Exhaust Camshaft Position Not Plausible
Circuit/System Description
The engine control module (ECM) uses the crankshaft position sensor and the CMP actuator solenoid valves sensor information to monitor the correlation between the crankshaft and the camshaft positions.
Conditions for Running the DTC
| • | DTCP0335, P0336, P0340, P0341, P0365, P0366, P0641 or P0651 is not set. |
| • | The engine is cranking or running. |
| • | The camshaft position actuator solenoid valves are in the parked position. |
| • | The crankshaft and camshaft position signals are synchronised. |
| • | The DTCs run continuously when the above conditions are met. |
Conditions for Setting the DTC
The ECM detects the CMP actuator solenoid valve - inlet or CMP actuator solenoid valve - exhaust is greater than 10° before or after the nominal position for 4 out of 5 camshaft revolutions in relation to the crankshaft angle while the engine is spinning.
Action Taken When the DTC Sets
DTCs P0016 and P0017 are Type B DTCs.
Conditions for Clearing the DTC
DTCs P0016 and P0017 are Type B DTCs.
Diagnostic Aids
The following conditions can also set the DTC:
| • | A short to ground in a CMP actuator solenoid valve control circuit. |
| • | Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, CMP sensor, crankshaft position sensor, or timing chain. |
| • | Excessive crankshaft end play. |
| • | An actuator that is in the full advance or retard position. |
| • | A crankshaft reluctor wheel that has moved in relationship to top dead centre (TDC). |
| • | Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, or caused by a condition with the crankshaft timing. |

Circuit/System Verification
- Vehicle in Service Mode, observe the DTC information with a scan tool. DTC P0010, P0011, P0013, P0014, P0335, P0336, P0340, P0341, P0365 or P0366 should not be set.
- Engine idling at the normal operating temperature. DTCs P0016 or P0017 should not set.
| ⇒ | If a DTC sets, inspect for the following: |
| • | The correct installation of the Q6F CMP actuator solenoid valve - inlet or Q6E CMP actuator solenoid valve - exhaust |
| • | The correct installation of the B26 Crankshaft Position Sensor |
| • | A timing chain tensioner condition |
| • | An incorrectly installed timing chain |
| • | Excessive play in the timing chain |
| • | A timing chain that jumped teeth |
| • | A crankshaft reluctor wheel that has moved in relationship to top dead center (TDC) on the crankshaft |
- Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that are captured in the freeze frame/failure records data.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
