Volvo All Engines (2017 Emissions) Fault Code: P001676 PID: EMS Crankshaft Position – Camshaft Position Correlation
Volvo All Engines (2017 Emissions) Fault Code: P001676 PID: EMS Crankshaft Position – Camshaft Position Correlation
The camshaft position (CMP) sensor is an inductive device. As the camshaft turns, the tip of the CMP sensor senses the teeth of the tone wheel fastened to the camshaft vibration damper. The CMP sensor sends a series of voltage pulses to the Engine Control Module (ECM). The frequency of the pulses is translated into engine speed (RPM) and position by the ECM. The ECM uses this information along with the information from Crankshaft Position (CKP) sensor to synchronize fuel injection.
Conditions for diagnostic trouble code (DTC):
1) The camshaft position sensor (CMP) signal has incorrect timing compared to the crankshaft position sensor (CKP) signal
Observable symptoms
1) High fuel consumption
Probable cause
1) Engine geartrain
Detailed information
1) The camshaft geartrain is incorrectly timed
