DTC P0335: Crankshaft Position Sensor "A" Circuit: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Select the following menu items: Powertrain / Engine / Data List / All Data / Engine Speed.
5. Put the engine in inspection mode. Refer to INSPECTION MODE PROCEDURE .
6. Read the values displayed on the Techstream while the engine is running.

   Standard

   Correct values are displayed.

   HINT: 

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

OK → See step   8 

NG: Go to next step 

1. Disconnect the C20 CKP sensor connector.

2. Measure the resistance between terminals 1 and 2.

   Standard resistance

   Tester Connections	Conditions	Specified Conditions
   1 - 2	Cold	985 to 1,600 Ω
   1 - 2	Hot	1,265 to 1,890 Ω

   HINT: 

   Terms "cold" and "hot" refer to the temperature of 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 CKP sensor connector.

NG → See step   9 

OK: Go to next step 

1. Disconnect the C20 CKP sensor connector.
2. Disconnect the C64 hybrid vehicle control ECU connector.
3. Measure the resistance.

   Standard resistance (Check for open)

   Tester Connections	Condition	Specified Conditions
   C20-1 - C64-69 (NE+)	Always	Below 1 Ω
   C20-2 - C64-68 (NE-)	Always	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connections	Condition	Specified Conditions
   C20-1 or C64-69 (NE+) - Body ground	Always	10 k Ωor higher
   C20-2 or C64-68 (NE-) - Body ground	Always	10 k Ωor higher

4. Reconnect the hybrid vehicle control ECU connector.
5. Reconnect the CKP sensor connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Check the CKP sensor installation.

   OK

   Sensor is installed correctly.

NG → SECURELY REINSTALL SENSOR 

OK: Go to next step 

1. Check the teeth on the sensor plate.

   OK

   Sensor plate does not have any cracks or deformation.

NG → REPLACE CRANKSHAFT POSITION SENSOR PLATE 

OK: Go to next step 

1. Replace the crankshaft position sensor. Refer to REMOVAL .

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Clear the DTCs. Refer to DTC CHECK / CLEAR .
5. Put the engine in inspection mode. Refer to INSPECTION MODE PROCEDURE .
6. Select the following menu items: Powertrain / Engine / Trouble Code.
7. Read the DTCs.

   Result

   No output	A
   P0335	B

   HINT: 

   If the engine does not start, replace the hybrid vehicle control ECU.

B → See step   10
