P0368 Camshaft Position Sensor "B" Circuit High Input (Bank 1)

DESCRIPTION

The camshaft position sensor (G signal) consists of a magnet and MRE (Magnet Resistance Element).

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

DTC No.

CONFIRMATION DRIVING PATTERN

These DTCs are detected when the engine is running or the engine cranks 100 revolutions or more.

CAUTION / NOTICE / HINT

Note:

  • After replacing the ECM, perform idle learning.

  • If any DTCs related to the manifold absolute pressure sensor, accelerator pedal sensor assembly and camshaft position sensor are output simultaneously, inspect the VC circuit of each component.

Tip:

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
