DTC P0335: Crankshaft Position Sensor "A" Circuit; DTC P0339: Crankshaft Position Sensor "A" Circuit Intermittent: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Data List / All Data / Engine Speed.
5. Start the engine.
6. Read the values displayed on the Techstream while the engine is running.

   OK

   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 at zero (0), there may be an open or short in the crankshaft position sensor circuit.

NG → See step   2 

OK → See step   8 

1. Inspect the crankshaft position sensor, refer to INSPECTION .

NG → See step   9 

OK: Go to next step 

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 (Check for Open)

   Tester Connection	Condition	Specified Condition
   B21-1 - B50-14 (NE+)	Always	Below 1 Ω
   B21-2 - B50-2 (NE-)	Always	Below 1 Ω

   Standard Resistance (Check for Short)

   Tester Connection	Condition	Specified Condition
   B21-1 or B50-14 (NE+) - Body ground	Always	10 kΩ or higher
   B21-2 or B50-2 (NE-) - Body ground	Always	10 kΩ or higher

4. Reconnect the crankshaft position sensor connector.
5. Reconnect the ECM connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Check the crankshaft position sensor installation.

   OK

   Sensor is installed correctly.

NG → See step   10 

OK: Go to next step 

1. Check the teeth of the crank angle sensor plate.

   OK

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

NG → See step   11 

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 ignition switch to ON.
3. Turn the Techstream on.
4. Clear the DTCs, refer to DTC CHECK / CLEAR .
5. Turn the ignition switch off.
6. Start the engine.
7. Enter the following menus: Powertrain / Engine / Trouble Codes.
8. Read the DTCs.

   Result

   Result	Proceed to
   DTC is not output	A
   DTC P0335 or P0339 is output	B

   HINT: 

   If the engine does not start, replace the ECM.

B → See step   12 

A → REPAIR COMPLETED
