Is the CKP sensor correctly installed?
Yes
Goto B2

No
INSTALL 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 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 GROUND WIRE FOR OPEN CIRCUIT

1. Disconnect the PCM electrical connector EN16.
2. Disconnect the CKP sensor electrical connector EN12.
3. Measure the resistance between the CKP sensor electrical connector EN12, pin 1 (Y) and the PCM electrical connector EN16, pin 37 (Y).

Is the resistance less than 5 ohms?
Yes
Goto B4

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

B4 : CHECK THE CKP SENSOR SIGNAL WIRE FOR OPEN CIRCUIT

1. Measure the resistance between the CKP sensor electrical connector EN12, pin 2 (P) and the PCM electrical connector EN16, pin 36 (P).

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 GROUND WIRE FOR A SHORT TO GROUND

1. Measure the resistance between the CKP sensor electrical connector EN12 pin 1 (Y) 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 B6

B6 : CHECK THE CKP SENSOR SIGNAL WIRE FOR A SHORT TO GROUND

1. Measure the resistance between the CKP sensor electrical connector EN12 pin 2 (P) 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 GROUND WIRE FOR A SHORT TO BATTERY

1. Turn the ignition switch to the ON position.
2. Measure the voltage between the CKP sensor electrical connector EN12 pin 1 (Y) and GROUND.

Is the voltage greater than 1 volt?
Yes
REPAIR the short to battery. 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 SIGNAL WIRE FOR A SHORT TO BATTERY

1. Turn the ignition switch to the ON position.
2. Measure the voltage between the CKP sensor electrical connector EN12 pin 2 (P) and GROUND.

Is the voltage greater than 1 volt?
Yes
REPAIR the short to battery. 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. Before replacing a PCM, contact Dealer technical support.
