D1 : PRELIMINARY DIAGNOSIS FOR DTCS P0335, P0336, OR P2617
NOTE:
- Some DTCs require that the engine goes through more than one ignition cycle to set.
- DTC P0336 and P2617 are calibrated to an increment counter. To set a DTC, greater than 10 consecutive events in the crank or run mode are required. Carry out the required number of ignition cycles from RUN to START to RUN (cycling to OFF resets the timer) and then carry out the KOEO or KOER self-test. Quick Test Description
- Carry out a visual inspection.
- Retrieve and record all DTCs.
- Record the freeze frame data.
- Clear the DTCs.
- Carry out the KOEO self-test. Quick Test Description
- Carry out the KOER self-test. Quick Test Description
- Is DTC P0335, P0336, or P2617 present?
-----------------------------------------------
D2 : DIAGNOSTIC TROUBLE CODE (DTC) P0335 OR P0336
- Possible causes:
- one or both sensor outputs open
- one or both sensor outputs short to ground
- sensor outputs short together
- one output open and the other output short to ground
- sensor output short to voltage
- CKP sensor
- PCM
- Does the engine start?
-----------------------------------------------
D3 : CHECK THE RESISTANCE OF THE CKP SENSOR
- Ignition OFF.
- PCM connector disconnected.
- Measure the resistance between:
- Is the resistance between 300 Ohm - 400 Ohm?
-----------------------------------------------
D4 : VERIFY A PCM CONCERN
- Ignition OFF.
- Connect all the electrical connectors.
- Ignition ON, engine OFF.
- Clear the DTCs.
- Carry out the KOEO self-test. Quick Test Description
- Carry out the KOER self-test. Quick Test Description
- Is DTC P0335, P0336, or P2617 present?
-----------------------------------------------
D5 : CHECK THE CKP CIRCUITS FOR A SHORT TO GROUND
- CKP Sensor connector disconnected.
- Measure the resistance between:
- Measure the resistance between:
- Are the resistances greater than 10 kOhm?
-----------------------------------------------
D6 : CHECK THE CKP SENSOR CIRCUITS FOR AN OPEN
- Measure the resistance between:
- Are the resistances less than 5 Ohm?
-----------------------------------------------
D7 : DIAGNOSTIC TROUBLE CODE (DTC) P2617
NOTE:
- DTCs P2617 and P2614 may set simultaneously after an engine stalling event.
- DTC P0336 and P2617 are calibrated to an increment counter. To set a DTC, greater than 10 consecutive events in the crank or run mode are required. Carry out the required number of ignition cycles from RUN to START to RUN (cycling to OFF resets the timer) and then carry out the KOEO or KOER self-test. Quick Test Description
- Carry out the KOEO self-test. Quick Test Description
- Carry out the KOER self-test. Quick Test Description
- Is DTC P2617 present?
-----------------------------------------------
D8 : CHECK THE CRANKSHAFT POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- PCM connector disconnected.
- FICM_C connector disconnected.
- Ignition ON, engine OFF.
- Measure the voltage between:
- Is the voltage less than 0.2 V?
-----------------------------------------------
D9 : CHECK THE CRANKSHAFT POSITION SIGNAL CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Measure the resistance between:
- Is the resistance greater than 10 kOhm?
-----------------------------------------------
D10 : CHECK THE CRANKSHAFT POSITION SIGNAL CIRCUIT FOR AN OPEN
- Measure the resistance between:
- Is the resistance less than 5 Ohm?
-----------------------------------------------
D11 : CHECK FOR CORRECT PCM OPERATION
- Disconnect all the PCM connectors.
- Visually inspect for:
- pushed out pins
- corrosion
- Connect all the PCM connectors and make sure they seat correctly.
- Carry out the PCM self-test and verify the concern is still present.
- Is the concern still present?
