DTC P0365: Camshaft Position Sensor "B" Circuit (Bank 1); DTC P0367: Camshaft Position Sensor "B" Circuit Low Input (Bank 1); DTC P0368: Camshaft Position Sensor "B" Circuit High Input (Bank 1): Description

The camshaft position sensor for exhaust camshaft (EV signal sensor) consists of a magnet and MRE.

The exhaust camshaft has a timing rotor for camshaft position sensor. When the camshaft rotates, changes occur in the air gaps between the timing rotor and MRE, which affects the magnet. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the camshaft rotation data to pulse signals, and uses the pulse signals to determine the camshaft angle, which it sends to the ECM. Then the ECM uses this data to control fuel injection duration, injection timing and the Variable Valve Timing (VVT) system.

DTC No.	DTC Detection Condition	Trouble Area
P0365	No camshaft position sensor signal is sent to the ECM at an engine speed of 600 rpm or more. (1 trip detection logic)	Open or short in exhaust camshaft position sensor circuit Exhaust camshaft position sensor Camshaft timing gear for exhaust camshaft Jumped tooth of timing chain for exhaust camshaft ECM
P0367	Output voltage of exhaust camshaft position sensor less than 0.3 V for 4 seconds (1 trip detection logic)	Open or short in exhaust camshaft position sensor circuit Exhaust camshaft position sensor ECM
P0368	Output voltage of exhaust camshaft position sensor more than 4.7 V for 4 seconds (1 trip detection logic)	Open or short in exhaust camshaft position sensor circuit Exhaust camshaft position sensor ECM

HINT:

DTC P0365, P0367 and P0368 indicate a malfunction relating to the exhaust camshaft position sensor circuit (the wire harness between the ECM and exhaust camshaft position sensor, and the exhaust camshaft position sensor itself).
