DTC P0107-00: Map Sensor Circuit Low Input: Notes

DTC P0107-00 PCM (SKYACTIV-G 2.5T) DETECTION CONDITION AND POSSIBLE CAUSE

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 1BD isbelow 0.28 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/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 Short to ground in wiring harness between the following terminals: MAP sensor/IAT sensor No. 2 terminal C-PCM terminal 1CM MAP sensor/IAT sensor No. 2 terminal D-PCM terminal 1BD MAP sensor signal circuit and ground circuit are shorted to each other MAP sensor malfunction PCM malfunction

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 1BD isbelow 0.28 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/Snapshot data is available.
DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

POSSIBLE CAUSE

MAP sensor/IAT sensor No. 2 connector or terminals malfunction
PCM connector or terminals malfunction
Short to ground in wiring harness between the following terminals:
- MAP sensor/IAT sensor No. 2 terminal C-PCM terminal 1CM
- MAP sensor/IAT sensor No. 2 terminal D-PCM terminal 1BD
MAP sensor signal circuit and ground circuit are shorted to each other
MAP sensor malfunction
PCM malfunction
