DTC Descriptor
DTC P0016
- Crankshaft Position (CKP) Camshaft Position (CMP) Correlation
Circuit/System Description
The engine control module (ECM) uses the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor pulses to monitor the
correlation between the crankshaft and the camshaft position. The crankshaft reluctor wheel consists of a 60-tooth pattern with 2 teeth missing for
the reference gap. Each tooth is evenly spaced 6 degrees apart, except for the reference gap. The camshaft reluctor wheel has 4 teeth, 2 narrow, and
2 wide. The 4 trailing edges of each tooth are evenly spaced at 90 degrees apart around the circumference of the camshaft sprocket. With the engine
running, and the CMP actuator in the parked position, the ECM expects the camshaft signal pulses to occur 36 crankshaft degrees before top dead
center (BTDC) for cylinder number 1, and every 90 degrees thereafter.
Conditions for Running the DTC
* DTC P0335, P0336, P0340, P0341, P0641, or P0651 is not set.
* The engine is running.
* The engine speed is less than 2,000 RPM.
* DTC P0016 runs continuously when the above conditions are met.
Conditions for Setting the DTC
The ECM detects that the CMP sensor pulses occur more than 11 crank degrees before, or 11 crank degrees after, nominal position for 24 out of 30
engine cycles.
Action Taken When the DTC Sets
DTC P0016 is a Type B DTC.
Conditions for Clearing the DTC
DTC P0016 is a Type B DTC.
