DTC P0335-2A: Crankshaft Position Sensor "A" Signal Stuck in Range; DTC P0335-31: Crankshaft Position Sensor "A" No Signal [12/2023 - ]: Procedure

Pre-procedure1

• Put the engine in Inspection Mode (2WD for measuring Exhaust Gas).

  Powertrain > Hybrid Control > Utility 

  Tester Display
  Inspection Mode

• Start the engine.

• Read the values displayed on the GTS while the engine is running.

  Powertrain > Engine > Data List 

  Tester Display
  Engine Speed

  Standard

  Correct values are displayed.

  HINT: 

  • To check the engine speed change, display the graph on the GTS.
  • If the engine does not start, check the engine speed while cranking.
  • If the engine speed indicated on the GTS remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.

  Result

  Proceed to
  OK
  NG

Post-procedure1

• None.

Result: 

OK 

CHECK FOR INTERMITTENT PROBLEMS. Refer to  CHECK FOR INTERMITTENT PROBLEMS [12/2023 - ] 

Result: 

NG 

See step  2

HINT: 

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

Pre-procedure1

• Disconnect the crankshaft position sensor connector.
• Turn the ignition switch ON.

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

  Standard Voltage

  Tester Connection	Condition	Specified Condition	Result
  C106-3 (VC) - Body ground	Ignition switch ON	4.5 to 5.5 V	V
  C106-1 (NE+) - Body ground	Ignition switch ON	3.0 to 5.5 V	V

Pre-procedure2

• Turn the ignition switch off and wait for at least 30 seconds.

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

  Standard Resistance

  Tester Connection	Condition	Specified Condition	Result
  C106-3 (VC) - C106-1 (NE+)	Ignition switch off	1.425 to 1.575 kΩ	kΩ
  C106-2 (NE-) - Body ground	Always	Below 1 Ω	Ω

  Result

  Proceed to
  OK
  NG

Post-procedure1

• None.

Result:

1. Visually check the crankshaft position sensor for damage.
2. Check the crankshaft position sensor installation condition.

   OK

   The crankshaft position sensor does not have any damage and is installed properly.

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPLACE OR SECURELY REINSTALL CRANKSHAFT POSITION SENSOR 

Result: 

OK 

See step  4

1. Inspect the teeth of the crankshaft angle sensor plate.

   OK

   Crankshaft angle sensor plate does not have any cracks or deformation.

   Result

   Proceed to
   OK
   NG

Result: 

OK 

REPLACE CRANKSHAFT POSITION SENSOR. Refer to  REMOVAL [12/2023 - ] 

Result: 

NG 

REPLACE FLYWHEEL SUB-ASSEMBLY. Refer to  REMOVAL [12/2023 - ] 

Pre-procedure1
