DTC P0108:00 [SKYACTIV-G 2.0]


id0102h1701200

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 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.
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 D—PCM terminal 1BW
―  MAP sensor/IAT sensor No.2 terminal A—PCM terminal 1BX
―  MAP sensor/IAT sensor No.2 terminal C—PCM terminal 1BO
•  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.
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.
No
Go to the next step.
3
CLASSIFY MAP SENSOR MALFUNCTION OR WIRING HARNESS MALFUNCTION
•  Access the MAP PID using the M-MDS.
•  Verify the MAP PID value.
•  Is the MAP PID value 5 V or B+?
Yes
When the voltage is 5V
•  Go to Step 7.
When the voltage is B+
•  Go to Step 8.
No
Go to the next step.
4
INSPECT MAP SENSOR/IAT SENSOR NO.2 CONNECTOR CONDITION
•  Switch the ignition to 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 9.
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 9.
No
Go to the next step.
6
INSPECT MAP SENSOR
•  Reconnect all disconnected connectors.
•  Is there any malfunction?
Yes
Replace the MAP sensor/IAT sensor No.2, then go to Step 9.
No
Go to Step 9.
7
INSPECT MAP SENSOR/IAT SENSOR NO.2 CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  Disconnect the MAP sensor/IAT sensor No.2 connector and PCM connector.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  MAP sensor/IAT sensor No.2 terminal D—PCM terminal 1BW
―  MAP sensor/IAT sensor No.2 terminal A—PCM terminal 1BX
―  MAP sensor/IAT sensor No.2 terminal C—PCM terminal 1BO
•  Is there continuity?
Yes
Replace the MAP sensor/IAT sensor No.2, then go to Step 9.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
8
INSPECT MAP SENSOR/IAT SENSOR NO.2 CIRCUIT FOR SHORT TO POWER SUPPLY
•  Switch the ignition to off.
•  Disconnect the MAP sensor/IAT sensor No.2 connector and PCM connector.
•  Measure the voltage at the MAP sensor/IAT sensor No.2 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 the next step.
No
Replace the MAP sensor/IAT sensor No.2, 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.
•  Start the engine and warm it up completely.
•  Perform the KOEO or KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
