DTC P0107 Without RPO CTF
Circuit Description
The barometric pressure (BARO) sensor is part of the engine control module (ECM).
If the ECM detects a signal voltage that is excessively low voltage DTC P0107 will set. If the ECM detects a signal voltage that is excessively high DTC P0108 will set.
Conditions for Setting the DTC
| • | The BARO sensor voltage is less than 1.9 volts. |
| • | The above condition is met for more than 1 second. |
Action Taken When the DTC Sets
The ECM will operate the vehicle based on a BARO pressure of 100 kPa (14.5 psi).
Conditions for Clearing the DTC
| • | A current DTC Last Test Failed clears when the diagnostic runs and passes. |
