1. DTC Descriptor:
DTC P0340
DTC P0341
Camshaft position (CMP) sensor is used to detect camshaft position, and is associated with the crankshaft position. It sends signals
to the engine control module (ECM) to determine the upcoming fuel injection.
Engine Control Module (ECM) also uses the camshaft position sensor output to determine the camshaft to the crankshaft relative
position to control the valve timing of camshaft adjustment and conduct emergency operations.
Camshaft position sensor circuit includes the following:
– Reference Voltage: ECM provides a reference voltage to CMP sensor harness connector EN15 terminal C via ECM harness
connector EN01 terminal No.23.
–
Signal Circuit: ECM receives signal voltage from CMP sensor harness connector EN15 terminal A via ECM harness connector
EN01 terminal No.56.
– ECM Low Reference Voltage Circuit: ECM provides a low reference voltage to CMP sensor harness connector EN15 terminal
B via ECM harness connector EN01 terminal No.18.
