id0102h9701200

DTC P0108:00

MAP sensor circuit high input

DETECTION CONDITION

•  The PCM monitors the input voltage from the MAP sensor. If the input voltage at the PCM terminal 1BW is above 4.89 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 check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  Estimates MAP using MAF sensor and engine speed.

•  Restricts the upper limit of the engine speed.

•  Inhibits the evaporative purge control.

POSSIBLE CAUSE

•  MAP sensor/IAT sensor No.2 connector or terminals malfunction

•  PCM connector or terminals malfunction

•  MAP sensor malfunction

•  Short to power supply in wiring harness between MAP sensor/IAT sensor No.2 terminal D and PCM terminal 1BW

•  Open circuit in wiring harness between the following terminals:

―  MAP sensor/IAT sensor No.2 terminal C—PCM terminal 1BO

―  MAP sensor/IAT sensor No.2 terminal D—PCM terminal 1BW

―  MAP sensor/IAT sensor No.2 terminal A—PCM terminal 1BX

•  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	DETERMINE IF MAP SENSOR OR WIRING HARNESS MALFUNCTION • Access the MAP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Verify the MAP PID value. • Is the MAP PID value 5 V or B+?	Yes	Go to Step 7.
3		No	Go to the next step.
4	INSPECT MAP SENSOR/IAT SENSOR NO.2 CONNECTOR CONDITION • Switch the ignition off. • Disconnect the MAP sensor/IAT sensor No.2 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 10.
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, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
5		No	Go to the next step.
6	INSPECT MAP SENSOR • Reconnect all disconnected connectors. • Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Is there any malfunction?	Yes	Replace the MAP sensor/IAT sensor No.2, then go to Step 10. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
6		No	Go to Step 10.
7	DETERMINE IF MAP SENSOR SIGNAL CIRCUIT OR MAP SENSOR GROUND CIRCUIT MALFUNCTION • Switch the ignition off. • Disconnect the MAP sensor/IAT sensor No.2 connector. • Access the MAP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Verify the MAP PID value. • Is the MAP PID value 5 V or B+?	Yes	Go to the next step.
7		No	Go to Step 9.
8	INSPECT MAP SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT • Verify that the MAP sensor/IAT sensor No.2 connector is disconnected. • Switch the ignition off. • Disconnect the PCM connector. • Inspect for continuity between MAP sensor/IAT sensor No.2 terminal D (wiring harness-side) and PCM terminal 1BW (wiring harness-side). • Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between MAP sensor/IAT sensor No.2 terminal D and PCM terminal 1BW. If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to power supply. Go to Step 10.
