DTC P0108:00

DTC P0108:00	MAP sensor circuit high input
DETECTION CONDITION	The PCM monitors the input voltage from the MAP sensor. If input the voltage is above 4.9 V for 5 s , the PCM determines that the MAP sensor circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	MAP sensor connector or terminals malfunction PCM connector or terminals malfunction MAP sensor signal circuit and power supply circuit are shorted to each other Short to power supply in wiring harness between MAP sensor terminal D and PCM terminal 2AG MAP sensor malfunction Open circuit in wiring harness between the following terminals: MAP sensor terminal A-PCM terminal 2AV MAP sensor terminal D-PCM terminal 2AG PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot 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 CONDITION Switch the ignition to off. 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 and/or connector, then go to Step 9.
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR CONDITION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 9.
4		No	Go to the next step.
5	INSPECT MAP SENSOR SIGNAL AND POWER SUPPLY CIRCUITS FOR SHORT TO EACH OTHER MAP sensor and PCM connectors are disconnected. Inspect for continuity between MAP sensor terminals C and D (wiring harness-side). Is there continuity?	Yes	Repair or replace the malfunctioning wiring harness, then go to Step 9.
5		No	Go to the next step.
6	INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY MAP sensor and PCM connectors are disconnected. Switch the ignition to ON (engine off). Measure the voltage between MAP sensor terminal D (wiring harness-side) and body ground. Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
6		No	Go to the next step.
7	INSPECT MAP SENSOR Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION ). Is there any malfunction?	Yes	Replace the MAP sensor, then go to Step 9. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION ).
7		No	Go to the next step.
8	INSPECT MAP SENSOR CIRCUIT FOR OPEN CIRCUIT Switch the ignition to off. Disconnect the MAP sensor and PCM connectors. Inspect for continuity between the following terminals (wiring harness-side): MAP sensor terminal A-PCM terminal 2AV MAP sensor terminal D-PCM terminal 2AG Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Switch the ignition to ON (engine off). Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE ). Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST ). Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION ). Go to the next step.
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
10		No	DTC troubleshooting completed.
