DTC P0340: Camshaft Position Sensor "A" Circuit

Wiring Diagram

Wiring Diagram:

System Description
The CMP sensor located on the cylinder head cover 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 wave form 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.
