1A-90 Engine General Information and Diagnosis:
DTC P0340: Camshaft Position Sensor “A” Circuit
S6RW0C1104038
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 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.
