P1109 Fault Code: Understanding The Description And Troubleshooting Tips
The P1109 fault code refers to a problem with the Barometric Pressure (BARO) sensor in the Engine Control Module (ECM). This sensor is responsible for monitoring atmospheric pressure.
The ECM uses the BARO sensor output voltage, along with the Manifold Absolute Pressure (MAP) sensor output voltage, to estimate the appropriate intake airflow. When the BARO sensor output voltage exceeds a specified value, the ECM detects a malfunction and stores the P1109 code. This means that the BARO sensor circuit is out of range on the high side.
It indicates that there is an issue with the sensor or its wiring, which needs to be addressed to ensure proper engine performance.
FAQ
If you’re experiencing an engine light on or a service engine soon warning light, along with a rough idle and engine hesitation, fault code P1109 might be the culprit.
