DTC P0335 P0339 2AD-FHV

 

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 engine revolution. Based on these signals, the ECM calculates the crankshaft position and engine RPM. Using these calculations, the common rail injection system is controlled.

DTC No.	DTC Detection Condition	Trouble Area
P0335	No crankshaft position sensor signal to ECM while cranking (1 trip detection logic)	Open or short in crankshaft position sensor circuit Crankshaft position sensor Crankshaft position sensor No. 1 plate ECM
P0339	No crankshaft position sensor signal is input to ECM for 0.05 seconds or more, and conditions (a), (b) and (c) are met: (1 trip detection logic) (a) Engine speed is at 1,000 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 Crankshaft position sensor No. 1 plate ECM

 

NOTICE:

After replacing the ECM, the new ECM needs registration and initialization.

 

1.INSPECT CRANKSHAFT POSITION SENSOR

1. Disconnect the B42 crankshaft position sensor connector.

2. Measure the resistance of the sensor.

    

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   B42-1 (NE) - B42-2 (NE-)	Cold	835 to 1,400 ?
   B42-1 (NE) - B42-2 (NE-)	Hot	1,060 to 1,645 ?

   HINT:

   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).  

3. Reconnect the crankshaft position sensor connector.

 

NG	REPLACE CRANKSHAFT POSITION SENSOR

OK

2.CHECK WIRE HARNESS (CRANKSHAFT POSITION SENSOR - ECM)

1. Disconnect the B42 crankshaft position sensor connector.

2. Disconnect the B32 ECM connector.

3. Measure the resistance of the wire harness side connectors.

    

   Standard resistance:

   Tester Connection	Specified Condition
   B42-1 (NE) - B32-78 (NE+)	Below 1 ?
   B42-2 (NE-) - B32-77 (NE-)	Below 1 ?
   B42-1 (NE) or B32-78 (NE+) - Body ground	10 k? or higher
   B42-2 (NE-) or B32-77 (NE-) - Body ground	10 k? or higher

4. Reconnect the crankshaft position sensor connector.

5. Reconnect the ECM connector.

 

NG	REPAIR OR REPLACE HARNESS AND CONNECTOR

OK

3.CHECK CRANKSHAFT POSITION SENSOR (SENSOR INSTALLATION)

1. Check the sensor installation.

    

   OK:

   Sensor is installed correctly.

    

    

 

NG	REPAIR OR REPLACE CRANKSHAFT POSITION SENSOR

OK

4.CHECK CRANKSHAFT TIMING SPROCKET

1. Check the teeth of the crankshaft timing sprocket.

    

   OK:

   The sensor plate's teeth do not have any cracks or deformation.

 

NG	REPLACE CRANKSHAFT TIMING SPROCKET

OK
REPLACE ECM
