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 the 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 • Short to power supply in wiring harness between MAP sensor terminal D and PCM terminal 2AG • MAP sensor power supply circuit and signal circuit are shorted to each other • MAP sensor malfunction • Open circuit in wiring harness between the following terminals: ― MAP sensor terminal D—PCM terminal 2AG ― MAP sensor terminal A—PCM terminal 2AV • 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 SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service 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 • Turn the ignition switch 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 connector and/or terminals, 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 connector and/or terminals, then go to Step 9.
4		No	Go to the next step.
5	INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • MAP sensor and PCM connectors are disconnected. • Turn the ignition switch to the ON position (engine off). • Measure the voltage at the MAP sensor terminal D (wiring harness-side). • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
5		No	Go to the next step.
6	INSPECT MAP SENSOR POWER SUPPLY CIRCUIT AND SIGNAL CIRCUIT FOR SHORT TO EACH OTHER • MAP sensor and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between MAP sensor terminals C and D (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to each other, then go to Step 9.
6		No	Go to the next step.
7	INSPECT MAP SENSOR • Reconnect all disconnected connectors. • Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [L5].) • Is there any malfunction?	Yes	Replace the MAP sensor, then go to Step 9. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [L5].)
7		No	Go to the next step.
8	INSPECT MAP SENSOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Disconnect the MAP sensor and PCM connectors. • Inspect for continuity between the following terminals (wiring harness-side): ― MAP sensor terminal D—PCM terminal 2AG ― MAP sensor terminal A—PCM terminal 2AV • 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. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L5].) • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [L5].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L5].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L5].)
10		No	DTC troubleshooting completed.
