DTC P0335 Crankshaft Position Sensor "A" Circuit |
DTC P0339 Crankshaft Position Sensor "A" Circuit Intermittent |
DESCRIPTION
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 injection system is controlled.P0335DTC 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 (crankshaft)
- ECM
|
P0339DTC 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

WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK071X.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.
- 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 (HILUX_TGN26 RM0000013Z4018X.html).
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:
Tester Connection
| Condition
| Specified Condition
|
C6-1 (NE+) - C22-27 (NE+)
| Always
| Below 1 Ω
|
C6-2 (NE-) - C22-34 (NE-)
| Always
| Below 1 Ω
|
C6-3 (E) - Body ground
| Always
| Below 1 Ω
|
C6-1 (NE+) or C22-27 (NE+) - Body ground
| Always
| 10 kΩ or higher
|
C6-2 (NE-) or C22-34 (NE-) - Body ground
| Always
| 10 kΩ or higher
|
Reconnect the crankshaft position sensor connector.
Reconnect the ECM connector.
3.CHECK CRANKSHAFT POSITION SENSOR (SENSOR INSTALLATION) |
Check the sensor installation.
- OK:
- Sensor is installed correctly.
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.
5.INSPECT CAMSHAFT TIMING PULLEY |
Check the teeth of the camshaft timing pulley.
- OK:
- The sensor plate teeth do not have any cracks or deformation.
Replace the ECM (HILUX_TGN26 RM0000013Z001HX.html).
7.REPLACE CRANKSHAFT POSITION SENSOR |
Replace the crankshaft position sensor (HILUX_TGN26 RM0000013Z601PX.html).
8.REPAIR OR REPLACE HARNESS OR CONNECTOR |
Repair or replace the harness or connector.
9.SECURELY REINSTALL SENSOR |
Securely reinstall the sensor (HILUX_TGN26 RM0000013Z301RX.html).
10.REPLACE NO. 1 CRANKSHAFT POSITION SENSOR PLATE |
Replace the No. 1 crankshaft position sensor plate (HILUX_TGN26 RM00000147Q025X_01_0039.html).
11.REPLACE CAMSHAFT TIMING PULLEY |
Replace the camshaft timing pulley (HILUX_TGN26 RM00000147Q025X_01_0034.html).
12.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED |
Connect the intelligent tester to the DLC3.
Clear the DTCs (HILUX_TGN26 RM000000PDK120X.html).
Turn the ignition switch off for 30 seconds or more.
Start the engine and run it at 1000 rpm or more for 5 seconds or more.
Confirm that the DTC is not output again.
