2Kd-Ftv Engine Control. Dtc P0340 Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

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.

P0340
DTC Detection Drive Pattern	DTC Detection Condition	Trouble Area
Crank engine for 4 seconds (STA on)	STA on: No camshaft position sensor signal is sent to the ECM while cranking for 4 seconds or more (2 trip detection logic).	Open or short in camshaft position sensor circuit Camshaft position sensor Crankshaft position sensor Camshaft timing pulley ECM
Idle engine for 1 second (STA off)	STA off: When either condition below is met a certain number of times (1 trip detection logic): Camshaft position sensor signal is not input with an engine speed of 650 rpm or more. Phase deviation in crankshaft and camshaft position sensor signals with an engine speed of 650 to 3000 rpm.

HINT:

If DTC P0340 is stored, the following symptoms may appear:

Difficulty starting
Misfire
Combustion noise
Black smoke
White smoke
Lack of power

WIRING DIAGRAM

Refer to DTC P0335 (HILUX_TGN26 RM00000187F03CX_02.html).

INSPECTION PROCEDURE

NOTICE:

After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK043X.html) and initialization (HILUX_TGN26 RM000000TIN04FX.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

Inspect the camshaft position sensor (HILUX_TGN26 RM0000013ZH014X.html).

Go to step 7

OK

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

Disconnect the camshaft position sensor connector.

Disconnect the ECM connector.

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

Reconnect the camshaft position sensor connector.

Reconnect the ECM connector.

Go to step 8

OK

3.CHECK CAMSHAFT POSITION SENSOR (SENSOR INSTALLATION)

Dtc
P0340 Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

Check the sensor installation.
OK:
Sensor is installed correctly.

Go to step 9

OK

4.CHECK CAMSHAFT TIMING PULLEY

Check the condition of the camshaft timing pulley.
OK:
Timing pulley does not have any cracks or deformation.

Go to step 10

OK

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

Connect the intelligent tester to the DLC3.

Turn the ignition switch to ON.

Turn the tester on.

Clear the DTCs (HILUX_TGN26 RM000000PDK0TAX.html).

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

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

Turn the tester on.

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

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

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).
