1Vd-Ftv Engine Control. Dtc P0335 Crankshaft Position Sensor A Circuit

The crankshaft position sensor system consists of a crankshaft position sensor plate and pickup coil. The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of wound copper wire, an iron core and magnet. The sensor plate rotates, and a pulse signal is created as each tooth passes by the pickup coil. The pickup coil generates 34 signals for each revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the common rail system is controlled.

P0335
DTC Detection Drive Pattern	DTC Detection Condition	Trouble Area
Crank or start engine	When the following condition is met (for 5 seconds during cranking or 0.5 seconds during engine start) (1 trip detection logic): No crankshaft position sensor signal is sent to the ECM while cranking.	Open or short in crankshaft position sensor circuit Crankshaft position sensor No. 1 crankshaft position sensor plate ECM

P0339
DTC Detection Drive Pattern	DTC Detection Condition	Trouble Area
Engine running at 1000 rpm or more with vehicle stationary	No crankshaft position sensor signal is input to the ECM for 0.05 seconds or more, and conditions (a), (b) and (c) are met (1 trip detection logic): (a) Engine speed is 1000 rpm or more. (b) STA signal is off. (c) 3 seconds or more have elapsed after STA signal is switched from on to off.	Open or short in crankshaft position sensor circuit Crankshaft position sensor No. 1 crankshaft position sensor plate No. 2 camshaft timing sprocket ECM

INSPECTION PROCEDURE

NOTICE:

After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
After replacing the fuel supply pump assembly, the ECM needs initialization (Click here).
After replacing an injector assembly, the ECM needs registration (Click here).

HINT:

Read freeze frame data using the GTS. 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.
The Data List item Engine Speed is calculated from the output of the crankshaft position sensor.
A DTC is also stored when the ground of a shielded wire is faulty.

1.INSPECT CRANKSHAFT POSITION SENSOR

Inspect the crankshaft position sensor (Click here).

Go to step 7

OK

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

Disconnect the crankshaft position sensor connector.

Disconnect the ECM connector.

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

Standard Resistance:

for LHD
Tester Connection	Condition	Specified Condition
C65-1 (NE+) - C45-78 (NE+)	Always	Below 1 Ω
C65-2 (NE-) - C45-77 (NE-)	Always	Below 1 Ω
C65-1 (NE+) or C45-78 (NE+) - Body ground	Always	10 kΩ or higher
C65-2 (NE-) or C45-77 (NE-) - Body ground	Always	10 kΩ or higher

Standard Resistance:

for RHD
Tester Connection	Condition	Specified Condition
C65-1 (NE+) - C46-78 (NE+)	Always	Below 1 Ω
C65-2 (NE-) - C46-77 (NE-)	Always	Below 1 Ω
C65-1 (NE+) or C46-78 (NE+) - Body ground	Always	10 kΩ or higher
C65-2 (NE-) or C46-77 (NE-) - Body ground	Always	10 kΩ or higher

Reconnect the crankshaft position sensor connector.

Reconnect the ECM connector.

Go to step 8

OK

3.CHECK CRANKSHAFT POSITION SENSOR (SENSOR INSTALLATION)

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

Go to step 9

OK

4.CHECK NO. 1 CRANKSHAFT POSITION SENSOR PLATE

Check the teeth of the sensor plate.
OK:
The sensor plate teeth do not have any cracks or deformation.

Go to step 10

OK

5.INSPECT NO. 2 CAMSHAFT TIMING SPROCKET

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

Go to step 11

OK

6.REPLACE ECM

Replace the ECM (Click here).

Go to step 12

7.REPLACE CRANKSHAFT POSITION SENSOR

Replace the crankshaft position sensor (Click here).

Go to step 12

8.REPAIR OR REPLACE HARNESS OR CONNECTOR

Repair or replace the harness or connector.

Go to step 12

9.SECURELY REINSTALL SENSOR

Securely reinstall the sensor (Click here).

Go to step 12

10.REPLACE NO. 1 CRANKSHAFT POSITION SENSOR PLATE

Replace the No. 1 crankshaft position sensor plate (Click here).

Go to step 12

11.REPLACE NO. 2 CAMSHAFT TIMING SPROCKET

Replace the No. 2 camshaft timing sprocket (Click here).

NEXT

12.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED

Connect the GTS to the DLC3.

Clear the DTCs (Click here).

Turn the engine switch off for 30 seconds or more.

Start the engine and run it at 1000 rpm or more for 5 seconds or more.

Enter the following menus: Engine and ECT / Trouble Codes.

Confirm that the DTC is not output again.
