DESCRIPTION
The crankshaft position sensor system consists of a crankshaft position sensor plate and a pickup coil. The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of 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.

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.

WIRING DIAGRAM
INSPECTION PROCEDURE
- After replacing the ECM, the new ECM needs registration () and initialization ().
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 |
Disconnect the crankshaft position sensor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| 1 (NE+) - 2 (NE-) | Cold | 1630 to 2740 Ω |
| 1 (NE+) - 2 (NE-) | Hot | 2065 to 3225 Ω |
- 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).
| 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 (Check for Open):
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 |
| C65-3 - Body ground | Always | Below 1 Ω |
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 |
| C65-3 - Body ground | Always | Below 1 Ω |
- Standard Resistance (Check for Short):
for LHD| Tester Connection | Condition | Specified Condition |
| 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 |
for RHD| Tester Connection | Condition | Specified Condition |
| 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 |
| 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.
| 6.REPLACE CRANKSHAFT POSITION SENSOR |
Replace the crankshaft position sensor ().
| 7.REPAIR OR REPLACE HARNESS OR CONNECTOR |
| 8.SECURELY REINSTALL SENSOR |
Securely reinstall sensor ().
| 9.REPLACE NO. 1 CRANKSHAFT POSITION SENSOR PLATE |
Replace the No. 1 crankshaft position sensor plate ().
| 10.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED |
Connect the intelligent tester to the DLC3.
Turn the ignition switch off.
Start the engine and run it at 1000 rpm or more.
Confirm that the DTC is not output again.
- Perform the following procedure using the tester to determine whether or not the DTC judgment has been carried out.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input DTC P0335 and/or P0339.
Check that STATUS is NORMAL. If STATUS is INCOMPLETE or UNKNOWN, after increasing the engine speed to 1000 rpm for approximately 1 second, idle the engine for 5 minutes.
