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) (EV1 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 affect 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 time, injection timing and the VVT (Variable Valve Timing) system.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0365 | No exhaust camshaft position sensor signal for 5 seconds at an engine speed of 600 rpm or higher (1 trip detection logic). |
|
| P0367 | Output voltage of exhaust camshaft position sensor less than 0.3 V for 4 seconds (1 trip detection logic) |
|
| P0368 | Output voltage of exhaust camshaft position sensor higher than 4.7 V for 4 seconds (1 trip detection logic) |

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).
