DTC P0107:00

MAP sensor circuit low input

DETECTION CONDITION

•  The PCM monitors the input voltage from the MAP sensor. If the input voltage is below 0.1 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

•  Short to ground in wiring harness between MAP sensor terminal C and PCM terminal 2AU

•  PCM connector or terminals malfunction

•  Open circuit in wiring harness between MAP sensor terminal C and PCM terminal 2AU

•  Short to ground in wiring harness between MAP sensor terminal D and PCM terminal 2AG

•  MAP sensor signal circuit and ground circuit are shorted to each other

•  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 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	VERIFY PID DATA FOR MAP SENSOR MALFUNCTION • Connect the M-MDS to the DLC-2. • Access the MAP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [LF, L5].) • Disconnect the MAP sensor connector. • Is the voltage above 4.9 V?	Yes	Go to the next step.
3		No	Go to Step 9.
4	INSPECT POWER SUPPLY CIRCUIT VOLTAGE AT MAP SENSOR CONNECTOR • Switch the ignition to ON (engine off). • Measure the voltage between MAP sensor terminal C (wiring harness-side) and body ground. • Is the voltage within 4.5—5.5 V?	Yes	Go to the next step.
4		No	Go to Step 6.
5	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, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 12.
5		No	Replace the MAP sensor, then go to Step 12. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [LF, L5].)
6	INSPECT MAP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND • Switch the ignition to off. • Disconnect the MAP sensor connector. • Inspect for continuity between MAP sensor terminal C (wiring harness-side) and body ground. • 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 [LF, L5].) Go to Step 12.
6		No	Go to the next step.
7	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 terminal and/or connector, then go to Step 12.
7		No	Go to the next step.
8	INSPECT MAP SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • MAP sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor terminal C (wiring harness-side) and PCM terminal 2AU (wiring harness-side). • Is there continuity?	Yes	Go to Step 12.
8		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
9	INSPECT MAP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Switch the ignition to off. • Disconnect the MAP sensor and PCM connectors. • Inspect for continuity between MAP sensor terminal D (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 12.
9		No	Go to the next step.
10	INSPECT MAP SENSOR SIGNAL AND GROUND CIRCUITS FOR SHORT TO EACH OTHER • MAP sensor and PCM connectors are disconnected. • Inspect for continuity between MAP sensor terminals D and A (wiring harness-side). • Is there continuity?	Yes	Repair or replace the malfunctioning wiring harness, then go to Step 12.
10		No	Go to the next step.
11	INSPECT MAP SENSOR • Reconnect the MAP sensor and PCM connectors. • Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [LF, L5].) • Is there any malfunction?	Yes	Replace the MAP sensor, then go to the next step. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [LF, L5].)
11		No	Go to the next step.
12	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 [LF, L5].) • Perform the KOEO/KOER self test. (See KOEO/KOER SELF TEST [LF, L5].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [LF, L5].)
12		No	Go to the next step.
13	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [LF, L5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [LF, L5].)
13		No	DTC troubleshooting completed.
