DTC P0340

Wiring Diagram:

System Description

The CMP sensor located on the cylinder head consists of the signal generator (magnetic sensor) and signal rotor (fixed to intake camshaft).
The signal generator generates reference signal through slits in the signal rotor 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. Pinout Values and Diagnostic Parameters Based on CMP sensor signal and CKP sensor signal, ECM judges which cylinder piston is in the compression stroke.

DTC Confirmation Procedure

NOTE: If DTC other than aimed DTC are previously detected in DTC confirmation procedure, be sure to troubleshoot DTC previously detected.
