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 pulley) has five teeth on its outer circumference and is installed on the camshaft. When the camshaft 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 crankshaft angle sensor plate. The NE signal sensor generates 34 signals for every revolution. The ECM detects the camshaft angle based on the G signal, and detects the crankshaft angle based on the NE signal.

WIRING DIAGRAM

Refer to DTC P0335 (HILUX_TGN26 RM00000187F039X_02.html).

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK040X.html) and initialization (HILUX_TGN26 RM000000TIN04CX.html).
HINT:
Read freeze frame data using the intelligent tester. 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, and other data from the time the malfunction occurred.
1.INSPECT CAMSHAFT POSITION SENSOR

  1. Inspect the camshaft position sensor (HILUX_TGN26 RM0000013ZH015X.html).



NG
Go to step 7
OK


2.CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM)

  1. Disconnect the camshaft position sensor connector.

  1. Disconnect the ECM connector.

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

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    C7-1 - C23-23 (G+)
    		Always
    		Below 1 Ω
    C7-2 - C23-31 (G-)
    		Always
    		Below 1 Ω
    C7-1 or C23-23 (G+) - Body ground
    		Always
    		10 kΩ or higher
    C7-2 or C23-31 (G-) - Body ground
    		Always
    		10 kΩ or higher

  1. Reconnect the camshaft position sensor connector.

  1. Reconnect the ECM connector.



NG
Go to step 8
OK


3.CHECK CAMSHAFT POSITION SENSOR (SENSOR INSTALLATION)

  1. Check the sensor installation.

    OK:
    Sensor is installed correctly.


NG
Go to step 9
OK


4.CHECK CAMSHAFT TIMING PULLEY

  1. Check the condition of the camshaft timing pulley.

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


NG
Go to step 10
OK


5.CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR CIRCUIT)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the tester on.

  1. Clear the DTCs (HILUX_TGN26 RM000000PDK0SYX.html).

  1. Turn the ignition switch off and wait for 30 seconds or more.

  1. Start the engine and idle it for 4 seconds or more.

  1. Turn the tester on.

  1. Check the engine condition while wiggling the crankshaft position sensor wire harness for 4 seconds or more when idling.

  1. Enter the following menus: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

    Result
    Result
    		Proceed to
    Except below
    		A
    There are problem such as rough idle or engine stall when wire harness is wiggles, or DTC is output*
    		B
    HINT:
    *: As the DTC was stored due to a change in the contact resistance of the connector, repair or replace the wire harness or connector (HILUX_TGN26 RM000004QR6001X.html).
