DTC P0335: Crankshaft Position Sensor "A" Circuit: Procedure
- READ VALUE USING TECHSTREAM (ENGINE SPEED)
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Put the engine in inspection mode (maintenance mode). Refer to INSPECTION MODE PROCEDURE .
- Start the engine.
- Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Engine Speed.
- 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 at zero (0), there may be an open or short in the crankshaft position sensor circuit.
NG → See step 2
OK → See step 6
- INSPECT CRANKSHAFT POSITION SENSOR (RESISTANCE)
- Inspect the crankshaft position sensor. Refer to INSPECTION .
NG → See step 7
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)
- Disconnect the crankshaft position sensor connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition D27-1 (NE) - D28-74 (NE+) Always Below 1 Ω D27-2 (NE-) - D28-120 (NE-) Always Below 1 Ω D27-1 (NE) or D28-74 (NE+) - Body ground Always 10 kΩ or higher D27-2 (NE-) or D28-120 (NE-) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK SENSOR INSTALLATION (CRANKSHAFT POSITION SENSOR)

- Check the crankshaft position sensor installation.
OK
Crankshaft position sensor is installed correctly.
NG → See step 8
OK: Go to next step
- Check the crankshaft position sensor installation.
- INSPECT NO. 1 CRANKSHAFT POSITION SENSOR PLATE
- 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.
NG → See step 9
OK → See step 10
- Inspect the teeth of the No. 1 crankshaft position sensor plate.
- CHECK FOR INTERMITTENT PROBLEMS. Refer to CHECK FOR INTERMITTENT PROBLEMS
- REPLACE CRANKSHAFT POSITION SENSOR. Refer to REMOVAL
- SECURELY REINSTALL CRANKSHAFT POSITION SENSOR. Refer to INSTALLATION
- REPLACE NO. 1 CRANKSHAFT POSITION SENSOR PLATE. Refer to COMPONENTS
- REPLACE ECM. Refer to REMOVAL
