DTC P0335-1F: Crankshaft Position Sensor "A" Circuit Intermittent; DTC P0335-2A: Crankshaft Position Sensor "A" Signal Stuck in Range; DTC P0335-31: Crankshaft Position Sensor "A" No Signal [12/2019 - 10/2022]: Procedure

1. Check the engine cranking condition.

   Result

   Result	Proceed to
   Cranking is OK	A
   Does not crank at all*	B

   HINT: 

   *: When the engine cannot crank, there may be a malfunction in the starter assembly.

Result: 

B 

GO TO PROBLEM SYMPTOMS TABLE (ENGINE DOES NOT CRANK (DOES NOT START)) 

Refer to PROBLEM SYMPTOMS TABLE [12/2019 - 10/2022]

Result: 

A 

See step  2

1. Start the engine.
2. 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.

HINT: 

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

1. Disconnect the crankshaft position sensor connector.
2. Turn the ignition switch to ON.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   n7-3 (VC) - Body ground	Ignition switch ON	4.5 to 5.5 V
   n7-1 (NE+) - Body ground	Ignition switch ON	3.0 to 5.0 V

4. Turn the ignition switch off and wait for at least 30 seconds.
5. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   n7-3 (VC) - n7-1 (NE+)	Ignition switch off	1.425 to 1.575 kΩ
   n7-2 (NE-) - Body ground	Always	Below 1 Ω

   Result

   Proceed to
   OK

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 

SECURELY REINSTALL CRANKSHAFT POSITION SENSOR 

Refer to INSTALLATION [12/2019 - 10/2022]

Result: 

OK 

See step  5

1. Inspect the teeth of the No. 1 crankshaft position sensor plate.

   OK

   No. 1 crankshaft position sensor plate does not have any cracks or deformation.

   Result

   Proceed to
   OK
   NG

Result: 

OK 

REPLACE CRANKSHAFT POSITION SENSOR 

Refer to REMOVAL [12/2019 - 10/2022]

Result: 

NG 

REPLACE NO. 1 CRANKSHAFT POSITION SENSOR PLATE 

Refer to REMOVAL [12/2019 - 10/2022]

1. Disconnect the crankshaft position sensor connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   n7-3 (VC) - C54-96 (VCNE)	Always	Below 1 Ω
   n7-2 (NE-) - C54-95 (NE-)	Always	Below 1 Ω
   n7-1 (NE+) - C54-128 (NE+)	Always	Below 1 Ω
   n7-3 (VC) or C54-96 (VCNE) - Body ground and other terminals	Always	10 kΩ or higher
   n7-2 (NE-) or C54-95 (NE-) - Body ground and other terminals	Always	10 kΩ or higher
   n7-1 (NE+) or C54-128 (NE+) - Body ground and other terminals	Always	10 kΩ or higher
