DTC P0107:00	MAP sensor circuit low input
DETECTION CONDITION	• The PCM monitors input voltage from the MAP sensor. If the input voltage is below 0.10 V for 5 s, the PCM determines that the MAP sensor circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA (Mode 2)/Snapshot data is available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE	• MAP sensor/boost air temperature sensor connector or terminals malfunction • Short to ground in wiring harness between the following terminals: ― MAP sensor/boost air temperature sensor terminal C—PCM terminal 2AU ― MAP sensor/boost air temperature sensor terminal D—PCM terminal 2AG • PCM connector or terminals malfunction • MAP sensor signal circuit and ground circuit are shorted to each other • Open circuit in wiring harness between MAP sensor/boost air temperature sensor terminal C and PCM terminal 2AU • MAP sensor malfunction • 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 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/BOOST AIR TEMPERATURE SENSOR CONNECTOR CONDITION • Turn the ignition switch off. • Disconnect the MAP sensor/boost air temperature sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, and 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 MAP SENSOR CIRCUIT FOR SHORT TO GROUND • MAP sensor/boost air temperature sensor connector is disconnected. • Inspect for continuity between the following terminals (wiring harness-side) and body ground: ― MAP sensor/boost air temperature sensor terminal C ― MAP sensor/boost air temperature sensor terminal D • Is there continuity?	Yes	If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [L3 Turbo].) Go to Step 9.
4		No	Go to the next step.
5	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 9.
5		No	Go to the next step.
6	INSPECT MAP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER • MAP sensor/boost air temperature sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor/boost air temperature sensor terminals D and A (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 POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • MAP sensor/boost air temperature sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor/boost air temperature 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 for a possible open circuit, then go to Step 9.
8	INSPECT MAP SENSOR • Reconnect all disconnected connectors. • Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [L3 Turbo].) • Is there any malfunction?	Yes	Replace the MAP sensor/boost air temperature sensor, then go to the next step. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [L3 Turbo].)
8		No	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 [L3 Turbo].) • Start engine and warm it up completely. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [L3 Turbo].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
10		No	DTC troubleshooting completed.
