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 element.

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 element, 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 DETECTION CONDITION CHART

DTC No.	DTC Detection Condition	Trouble Area
P0365	When one of following conditions is met: No exhaust camshaft position sensor signal to ECM while cranking (2 trip detection logic) Missing exhaust camshaft position sensor signal signal for 5 seconds at engine speed of 600 rpm or more (1 trip detection logic) Input voltage to ECM remains less than 0.3 V, or more than 4.7 V for 4 seconds when 2 or more seconds have elapsed after turning ignition switch ON (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 Camshaft timing gear for exhaust camshaft Jumped tooth of timing chain for exhaust camshaft ECM
P0368	Output voltage of exhaust camshaft position sensor 4.7 V for 4 seconds (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

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).
