DTC P007C-00: Boost Air Temperature Sensor Circuit Low Input: Notes
DTC P007C:00 DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P007C:00 |
Boost air temperature sensor circuit low input |
| DETECTION CONDITION |
- The PCM monitors the input signal from the boost air temperature sensor. If the voltage from the boost air temperature sensor is below 0.13 V, the PCM determines that the boost air temperature 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 |
- Boost pressure sensor/boost air temperature sensor connector or terminals malfunction
- Boost air temperature sensor malfunction
- Short to ground in wiring harness between boost pressure sensor/boost air temperature sensor terminal B and PCM terminal 2U
- PCM connector or terminals malfunction
- Boost air temperature sensor signal circuit and ground circuit are shorted to each other
- PCM malfunction
