DTC P0340: Camshaft Position (CMP) Sensor Circuit
S5JB0A1104041
Wiring Diagram
System Description
The CMP sensor located on the transmission side of cylinder head (for M16 engine) or cylinder head cover (for J20
engine) consists of the signal generator (magnetic sensor) and signal rotor (intake camshaft portion).
The signal generator generates reference signal through slits in the slit plate which turns together with the camshaft.
Reference signal
The CMP sensor generates 6 pulses of signals each of which has a different waveform length while the camshaft
makes one full rotation. Refer to “Inspection of ECM and Its Circuits: ”.
Based on these signals, ECM judges which cylinder piston is in the compression stroke and the engine speed.
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Crank engine for 5 sec.
4) Check DTC and pending DTC.
