P0335

B : DTC P0335, P0336, P1245, P1246. Crankshaft Position (CKP) Sensor.

B1 : CHECK THE CKP SENSOR FOR CORRECT INSTALLATION
1. Turn the ignition switch to the OFF position.
2. Check the CKP sensor for correct installation.

Is the CKP sensor correctly installed?

Yes
Goto B2

No
CLEAN the CKP sensor correctly.Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

B2 : CHECK THE CKP SENSOR FOR DEBRIS
1. Remove the CKP sensor and inspect for debris.

Is the CKP sensor and flywheel teeth free of debris?

Yes
Goto B3

No
CLEAN the sensor and wheel. Install the sensor. Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

B3 : CHECK THE CKP SENSOR RESISTANCE
1. Measure the resistance between pins 1 and 2 of the CKP sensor.

Is the resistance 250 to 450 ohms?

Yes
Goto B4

No
Install a new CKP sensor.Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

B4 : CHECK THE CKP SENSOR GROUND WIRE FOR OPEN CIRCUIT
1. Disconnect the PCM electrical connector PI01.
2. Disconnect the CKP sensor electrical connector PI21.
3. Measure the resistance between the CKP sensor electrical connector PI21, pin 1 (B) and the PCM electrical connector PI01, pin 37 (B).

Is the resistance less than 5 ohms?

Yes
Goto B5

No
Repair the circuit. For additional information, refer to the wiring diagrams. Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation.

B5 : CHECK THE CKP SENSOR SIGNAL WIRE FOR OPEN CIRCUIT
1. Measure the resistance between the CKP sensor electrical connector PI21, pin 2 (O) and the PCM electrical connector PI01, pin 36 (O).

Is the resistance less than 5 ohms?

Yes
Goto B6

No
Repair the circuit. For additional information, refer to the wiring diagrams. Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation.

B6 : CHECK THE CKP SENSOR GROUND WIRE FOR A SHORT TO GROUND
1. Measure the resistance between the CKP sensor electrical connector PI21 pin 1 (B) and GROUND.

Is the resistance less than 10,000 ohms?

Yes
Repair the short to GROUND. For additional information, refer to the wiring diagrams. Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation.

No
Goto B7

B7 : CHECK THE CKP SENSOR SIGNAL WIRE FOR A SHORT TO GROUND
1. Measure the resistance between the CKP sensor electrical connector PI21 pin 2 (O) and GROUND.

Is the resistance less than 10,000 ohms?

Yes
Repair the short to GROUND. For additional information, refer to the wiring diagrams. Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation.

No
Goto B8

B8 : CHECK THE CKP SENSOR GROUND WIRE FOR A SHORT TO BATTERY POSITIVE
1. Turn the ignition switch to the ON position.
2. Measure the voltage between the CKP sensor electrical connector PI21 pin 1 (B) and GROUND.

Is the voltage greater than 5 volts?

Yes
Repair the short to battery positive. For additional information, refer to the wiring diagrams. Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation.

No
Goto B9

B9 : CHECK THE CKP SENSOR SIGNAL WIRE FOR A SHORT TO BATTERY POSITIVE
1. Turn the ignition switch to the ON position.
2. Measure the voltage between the CKP sensor electrical connector PI21 pin 2 (O) and GROUND.

Is the voltage greater than 5 volts?

Yes
Repair the short to battery positive. For additional information, refer to the wiring diagrams. Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation.

No
Install a new CKP sensor.Reconnect all connectors. CLEAR the DTCs. TEST the system for normal operation. If the concern persists. INSTALL a new PCM.
