P1350

DTC P1350 VVT SENSOR/CAMSHAFT POSITION SENSOR CIRCUIT MALFUNCTION (BANK 2)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

VVT sensor RH consists of a core and a pick up coil.

On the signal plate for VVT signal, there are three convex on its outer circumference and it is fixed to the camshaft timing gear.

When the camshaft turns, the convex of the signal plate and the air-gap over the pick up coil will switch, and with this the magnetic field will change and generate electricity inside the pick up coil. In addition, VVT sensor LH adopts a sensor using a signal plate and a magnetic resistance element. By switching the air-gap of the signal plate and the sensor, ECM voltage will be converted to a rectangular move and output as a signal.

INSPECTION PROCEDURE

HINT:
- If DTC P1350 is displayed, check right bank VVT sensor (Crank position sensor NO.1).
- Read freeze frame data using hand-held tester or OBD II scan tool. 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.
