DTC P0108 DIAGNOSTIC PROCEDURE TABLE

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	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line 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	INSPECT MAP SENSOR CONNECTOR FOR POOR CONNECTION Disconnect the MAP sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
3		No	Go to the next step.
4	VERIFY MAP SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between the MAP sensor terminal A (wiring harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
4		No	Inspect for open circuit in the wiring harness between PCM terminal 2AV (wiring harness-side) and MAP sensor terminal A (wiring harness-side). Repair or replace suspected harness, then go to Step 8.
5	INSPECT PCM CONNECTOR FOR POOR CONNECTION Disconnect the PCM connector. Inspect for poor connection at terminals (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair the terminal, then go to Step 8.
5		No	Go to the next step.
6	VERIFY MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO CONSTANT VOLTAGE CIRCUIT Inspect for continuity between MAP sensor terminal D and C (wiring harness-side). Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 8.
6		No	Go to the next step.
7	VERIFY MAP SENSOR CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between the following: MAP sensor terminal D (wiring harness-side) and PCM terminal 2AG (wiring harness-side) MAP sensor terminal C (wiring harness-side) and PCM terminal 2AU (wiring harness-side) Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness, then go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0108 COMPLETED Make sure to reconnect all disconnected connectors. Turn the ignition switch to the ON position (Engine off). Clear the DTC from the memory using the WDS or equivalent. Start the engine. Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION .)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE" (See AFTER REPAIR PROCEDURE .) Are any DTC present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE .)
9		No	Troubleshooting completed.
