DTC P0107-00: Map Sensor Circuit Low Input: Outline
WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.
DTC P0107:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
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 1X is below 0.08 V for 5 s, the PCM determines that the MAP sensor circuit has a malfunction.
|
| Fail-safe |
- 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 any of the following MAP sensor circuits.
- Open circuit in MAP sensor power supply circuit
- Short circuit in MAP sensor signal circuit and ground circuit
- MAP sensor malfunction
- PCM malfunction
