DTC P0340 Camshaft Position Sensor "A" Circuit (Bank 1 or Single Sensor)


DESCRIPTION

The camshaft position sensor (G signal) consists of a magnet, iron core and pickup coil.
The G signal plate (timing sprocket) has one tooth on its outer circumference and is installed on the camshaft timing chain gear. When the timing gear rotates, the protrusion on the signal plate and the air gap on the pickup coil change, causing fluctuations in the magnetic field that generate a voltage in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crank angle sensor plate. The NE signal sensor generates 34 signals for every engine revolution. The ECM detects the standard crankshaft angle based on the G signal and the actual crankshaft angle and the engine speed by the NE signal.

DTC No.

WIRING DIAGRAM

Refer to DTC P0335 (see page RAV4_ACA30 RM00000187F006X_02.html).

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
After replacing the ECM, the new ECM needs registration (see page RAV4_ACA30 RM000000TJ400AX.html) and initialization (see page RAV4_ACA30 RM000000TIN009X.html).
1.INSPECT CAMSHAFT POSITION SENSOR


    Toyota Rav4. Aca30, 33, 38 Ala30.Система Управления Двигателем 2Ad-Ftv.Система Ecd. Dtc P0340 Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

  1. Disconnect the B35 camshaft position sensor connector.

  1. Measure the resistance of the camshaft position sensor.

    Standard resistance:
    Tester Connection
    		Specified Condition
    B35-1 - B35-2
    		835 to 1,400 Ω at cold
    B35-1 - B35-2
    		1,060 to 1,645 Ω at hot
    УКАЗАНИЕ:
    In the table above, the terms "Cold" and "Hot" refer to the temperature of the coils in the sensor. "Cold" means approximately -10 to 50°C (14 to 122°F). "Hot" means approximately 50 to 100°C (122 to 212°F).

  1. Reconnect the camshaft position sensor connector.

REPLACE CAMSHAFT POSITION SENSOR
OK


2.CHECK WIRE HARNESS (CAMSHAFT POSITION SENSOR - ECM)

  1. Disconnect the B35 camshaft position sensor connector.

  1. Disconnect the B32 ECM connector.

  1. Measure the resistance of the wire harness side connectors.

    Standard resistance:
    Tester Connection
    		Specified Condition
    B35-1 - B32-80 (G+)
    		Below 1 Ω
    B35-2 - B32-79 (G-)
    		Below 1 Ω
    B35-1 or B32-80 (G+) - Body ground
    		10 kΩ or higher
    B35-2 or B32-79 (G-) - Body ground
    		10 kΩ or higher

  1. Reconnect the camshaft position sensor connector.

  1. Reconnect the ECM connector.



NG
REPAIR OR REPLACE HARNESS AND CONNECTOR
OK


3.CHECK CAMSHAFT POSITION SENSOR (SENSOR INSTALLATION)

  1. Check the sensor installation.

    OK:
    Sensor is installed correctly.


NG
REPAIR OR REPLACE CAMSHAFT POSITION SENSOR
OK


4.CHECK CAMSHAFT TIMING SPROCKET

  1. Check the condition of the timing sprocket.

    OK:
    Timing sprocket does not have any cracks or deformation.
