DESCRIPTION

The exhaust camshaft's Variable Valve Timing (VVT) sensor consists of a magnet and MRE (Magnet Resistance Element).
The exhaust camshaft has a sensor plate with 3 teeth on its outer circumference.
When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which affects the magnet. As a result, the resistance of the MRE material fluctuates. The VVT sensor converts the exhaust camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft angle, and sends it to the ECM.

INSPECTION PROCEDURE

Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction (CAMRY_ACV40 RM000000PDS01FX.html).
1.CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE)


    Camry. Acv40 Gsv40.2Gr-Fe Engine Control System.Sfi System. Dtc P0365 Camshaft Position Sensor B Circuit (Bank 1)

  1. Disconnect the C40 or C44 VVT sensor connector.

  1. Measure the voltage according to the value(s) in the table below.

    Standard voltage:
    Tester Connection
    		Specified Condition
    VC2 (C40-3) - Body ground
    		4.5 to 5.0 V
    VC2 (C44-3) - Body ground
    		4.5 to 5.0 V

  1. Reconnect the VVT sensor connector.
