PINPOINT TEST G258127p17 : DTC P0335, P0336; CRANKSHAFT POSITION (CKP) SENSOR CIRCUIT RANGE/PERFORMANCE, CIRCUIT MALFUNCTION

G258127t61 : 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
GO to Pinpoint Test G258127t62.

->NO
INSTALL the CKP sensor correctly. Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

G258127t62 : CHECK THE CKP SENSOR FOR DEBRIS
1. Remove the CKP sensor and inspect for debris.

- Is the CKP sensor free of debris?

->YES
GO to Pinpoint Test G258127t63.

->NO
CLEAN the sensor and wheel. INSTALL the sensor. Reconnect the sensor. CLEAR the DTCs. TEST the system for normal operation.

G258127t63 : CHECK THE CKP SENSOR SENSING CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the ECM electrical connector, PI01.
3. Disconnect the CKP sensor electrical connector, PI21.
4. Measure the resistance between PI21, pin 02 (O) and PI01, pin 36 (O).

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G258127t64.

G258127t64 : CHECK THE CKP SENSOR SENSING CIRCUIT FOR SHORT TO HIGH VOLTAGE
1. Reconnect the battery negative terminal.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between PI21, pin 02 (O) and GROUND.

- Is the voltage greater than 3 volts?

->YES
REPAIR the short circuit to high voltage. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G258127t65.

G258127t65 : CHECK THE CKP SENSOR SENSING CIRCUIT FOR SHORT TO GROUND
1. Turn the ignition switch to the OFF position.
2. Measure the resistance between PI21, pin 02 (O) and GROUND.

- Is the resistance less than 10,000 Ohms?

->YES
REPAIR the short circuit to GROUND. CLEAR the DTC. TEST the system for normal operation.

->NO
GO to Pinpoint Test G258127t66.

G258127t66 : CHECK THE CKP SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between PI21, pin 01 (B) and PI01, pin 37 (B).

- Is the resistance greater than 5 Ohms?

->YES
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

->NO
INSTALL a new CKP sensor. CLEAR the DTC. TEST the system for normal operation.
