Diagnostic Procedure

DTC P0107 DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Recorded FREEZE FRAME DATA on repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Check for related Service Bulletins and/or online repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY MAP PID WHEN MAP SENSOR CONNECTOR IS DISCONNECTED Disconnect MAP sensor connector. Is voltage above 4.9 V ?	Yes	Go to the next step.
3		No	Go to step 5.
4	INSPECT POWER SUPPLY CIRCUIT VOLTAGE AT MAP SENSOR CONNECTOR NOTE: If DTC P0122 and P2228 are also retrieved with P0107, go to troubleshooting procedure. Turn ignition switch to ON (Engine off). Measure voltage between MAP sensor terminal C (wiring harness-side) and body ground. Is voltage within 4.5-5.5 V ?	Yes	Check for poor connection of MAP sensor terminal C (wiring harness-side). Repair or replace terminal if necessary. If normal, replace MAP sensor. Then go to Step 7.
4		No	Check for open circuit between PCM terminal 2AU (wiring harness-side) and MAP sensor terminal C (wiring harness side). Repair or replace suspected harness, then go to Step 7.
5	INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND Turn the ignition switch off. Disconnect PCM connector. Inspect continuity between MAP sensor terminal D (wiring harness-side) and body ground. Is there continuity?	Yes	Repair or replace suspected harness, then go to Step 7.
5		No	Go to the next step.
6	INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUIT FOR SHORT EACH OTHER Check continuity between MAP sensor terminals D and A (wiring harness-side). Is there continuity?	Yes	Repair or replace suspected harness, then go to the next step.
6		No	Go to the next step.
7	VERIFY TROUBLESHOOTING OF DTC P0107 COMPLETED Make sure to reconnect all disconnected connectors. Turn ignition switch to ON (Engine off). Clear the DTC from the PCM memory using the WDS or equivalent. Start engine and warm it up completely. Is same DTC present?	Yes	Replace PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION ).
7		No	Go to the next step.
8	VERIFY AFTER REPAIR PROCEDURE Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE ). Is any DTC present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
8		No	Troubleshooting completed.
