5. Repair Instructions:
Replaced the knock sensor. Refer to
2.2.7.31 DTC P0340-P0343
1. DTC Descriptor:
DTC P0340
DTC P0341
DTC P0342
DTC P0343
CMP links the crankshaft position to the camshaft position, so that ECM calculates cylinder No.1 compression TDC and determines
at what time to which cylinder spray fuel.
Camshaft position sensor circuit includes the following:
– Reference Voltage: ECM provides a reference voltage to CMP sensor harness connector EN15 terminal No.1 via ECM harness
connector EN01 terminal No.39.
–
Signal Circuit: ECM receives signal voltage from CMP sensor harness connector EN15 terminal No.2 via ECM harness connector
EN01 terminal No.42.
ECM Low Reference Voltage Circuit: ECM provides a low reference voltage to CMP sensor harness connector EN15 terminal No.
3 via ECM harness connector EN01 terminal No.14 and 18.
