DTC P0107: BARO Circuit, Low Input: Condition
PCM monitors voltage from EGR boost sensor when intake air temperature is more than 50°F (10°C) and EGR boost sensor solenoid is turned off (barometric pressure is applied to sensor). Code is set when input voltage from EGR boost sensor is less than .35 volts. This is a continuous monitor. MIL is illuminated when PCM detects malfunction during first drive cycle. Possible causes are:
- EGR boost sensor malfunction.
- Open or short circuit between EGR boost sensor and PCM.
- PCM malfunction.
- Poor connections.
