DTC P0107:00 [SKYACTIV-D 1.5]
id0102q2701100
DTC P0107:00 |
MAP sensor circuit low input |
---|---|
DETECTION CONDITION
|
• The PCM monitors the input voltage from the MAP sensor. If the input voltage at the PCM terminal 1BA is below 0.12 V for 4 s, the PCM determines that the MAP sensor circuit has a malfunction.
MONITORING CONDITIONS
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/Snapshot data is available.
• DTC is stored in the PCM memory.
|
FAIL-SAFE FUNCTION
|
• PCM restricts engine torque.
• Inhibits the auto DPF regeneration control.
• Inhibits the compulsory DPF regeneration control.
• Inhibits the boost control.
• Inhibits the EGR control.
• PCM restricts engine-transaxle integration control. (ATX)
• Inhibits engine-stop by operating the i-stop function.
|
POSSIBLE CAUSE
|
• MAP sensor/boost air temperature sensor connector or terminals malfunction
• PCM connector or terminals malfunction
• Short to ground in wiring harness between the following terminals:
• MAP sensor signal circuit and ground circuit are shorted to each other
• MAP sensor malfunction
• PCM malfunction
|
Diagnostic Procedure
STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the FREEZE FRAME DATA/snapshot data on the repair order.

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.

|
INSPECT MAP SENSOR/BOOST AIR TEMPERATURE SENSOR CONNECTOR CONDITION
• Switch the ignition off.
• Disconnect the MAP sensor/boost air temperature 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 8.
|
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 8.
|
No
|
Go to the next step.
|
||
5
|
INSPECT MAP SENSOR CIRCUIT FOR SHORT TO GROUND
• Verify that the MAP sensor/boost air temperature sensor and PCM connectors are disconnected.
• Inspect for continuity between the following terminals (wiring harness-side) and body ground:
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• MAP sensor/boost air temperature sensor terminal C—PCM terminal 1AZ
• MAP sensor/boost air temperature sensor terminal D—PCM terminal 1BA
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 ground.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to ground.
Go to Step 8.
|
No
|
Go to the next step.
|
||
6
|
INSPECT MAP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER
• Verify that the 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
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• MAP sensor/boost air temperature sensor terminal D—PCM terminal 1BA
• MAP sensor/boost air temperature sensor terminal A—PCM terminal 1BB
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 each other.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to each other.
Go to Step 8.
|
No
|
Go to the next step.
|
||
7
|
INSPECT MAP SENSOR
• Reconnect all disconnected connectors.
• Inspect the MAP sensor.
• Is there any malfunction?
|
Yes
|
Replace the MAP sensor/boost air temperature sensor, then go to the next step.
|
No
|
Go to the next step.
|
||
8
|
VERIFY DTC TROUBLESHOOTING COMPLETED
• Always reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• 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.
|
||
9
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the “AFTER REPAIR PROCEDURE”.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 1.5].)
|
No
|
DTC troubleshooting completed.
