DTC P0345 Camshaft Position Sensor "A" Circuit (Bank 2)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

Camshaft position sensor (G (VV) signal) consists of a magnet, iron core and pickup coil.

The G (VV) signal plate has 3 teeth, on its outer circumference and is installed the camshaft timing gear. When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil change, causing fluctuations in the magnetic field and generating an electromotive force in the pickup coil.

The actual camshaft angle is detected by the camshaft position sensor and it provides feedback to the ECM to control the intake valve timing in response to driving condition.

INSPECTION PROCEDURE

HINT:
- If DTC P0340 or P0341 is displayed, check right bank camshaft position sensor.
- If DTC P0345 or P0346 is displayed, check left bank camshaft position sensor.
- Read freeze frame data using OBD II scan tool or hand-held tester. Because freeze frame records the engine conditions when the malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc at the time of the malfunction.
