DTC P0017:Camshaft Position (CMP) Sensor B and Crankshaft Position (CKP) Sensor Correlation

General Description

The camshaft position sensoring operates based on pulse detection and counting. The fundamental components are a pulse plate mounted on the end of the shaft (rotary part) and camshaft position (CMP) sensor B mounted in line with the pulse plate including electronic circuitry (stationary part). Around the circumference of the pulse plate, there are teeth distributed evenly and additional reference markers. This makes it possible to generate an electric pulse pattern when the shaft rotates and the teeth are passing by CMP sensor B. The camshaft position can be determined by counting the number of pulses and deriving the pulse pattern of the electrical signal from CMP sensor B. If the powertrain control module (PCM) recognizes an angle offset of the exhaust camshaft greater or less than a specified value for at least a specified number of camshaft revolutions, a malfunction is detected and a DTC is stored.

Malfunction Threshold
Mounting error
The average offset angle of the adapted positions to the applied positions of the exhaust camshaft is greater than +6.9 °, or less than -13.4 °.
Offset error
The average offset angle with reference to crankshaft is greater than +7.84 °, or less than -11.84 ° for 10 camshaft revolutions.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
CMP sensor B installed incorrectly
Crankshaft position (CKP) sensor installed incorrectly
Cam chain poor installation

Confirmation Procedure
Operating Condition
Start the engine. Hold the engine speed [Engine Speed] at 3,000 rpm without load (in neutral) until the radiator fan comes on.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
