DTC Descriptors

DTC P0016
- Crankshaft Position - Intake 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 intake and exhaust camshaft position sensor information to monitor the correlation between the crankshaft and the camshaft positions.

Conditions for Running the DTC

* DTCs P0335, P0336, P0340, P0341, P0365, P0366, P0641 or P0651 is not set

* The engine is running.

* The camshaft actuators are in the parked position.

* DTC P0016 and P0017 run continuously once the above conditions are met.

Conditions for Setting the DTC

The ECM detects an camshaft to crankshaft misalignment. The DTC sets if the crankshaft position sensor signal is 10 degrees before or after the nominal position 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 voltage on the camshaft position actuator solenoid valve control circuit can cause this DTC to set.

* Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, camshaft position sensor, crankshaft position sensor, or timing belt can cause this DTC to set.

* A cam actuator that is in the full advance or retard position can cause this DTC to set.

* Crankshaft end play out of the range can cause this DTC to set.

* A crankshaft reluctor wheel that has moved in relationship to top dead center (TDC) can cause this DTC to set.

Circuit/System Verification

1. Ignition ON, observe the DTC information with a scan tool. DTCs P0335, P0336, P0340, P0341, P0365, P0366, P0641 or P0651 should not be set.

• If a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.

2. Engine idling at the normal operating temperature. DTCs P0016 or P0017 should not set.

• If a DTC is set, inspect for the following:

* The correct installation of the B23E Camshaft Position Sensor - Exhaust and the B23F Camshaft Position Sensor - Intake

* The correct installation of the B26 Crankshaft Position Sensor

* A timing belt tensioner condition

* An incorrectly installed timing belt

* Excessive play in the timing belt

* A timing belt that jumped teeth

* A crankshaft reluctor wheel that has moved in relationship to top dead center (TDC) on the crankshaft

• If you find a condition, repair as necessary.

3. 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.
