If you’re experiencing an engine light on, rough idle, and engine hesitation, you might be dealing with the p1107 fault code.

  • The fault code P1107 is associated with the following symptoms: Engine Light ON (or Service Engine Soon Warning Light), engine rough idle, and engine hesitation.

The automobile fault code p1107 can be caused by outdated or incorrect software in the Engine Control Module (ECM) or a faulty ECM.

  • The fault code p1107 can be caused by an outdated or incorrect software in the Engine Control Module (ECM).
  • Another possible cause is a faulty Engine Control Module (ECM).

To fix the p1107 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1107, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1107 include the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P1107 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, along with the Manifold Absolute Pressure (MAP) sensor, to estimate the appropriate intake airflow. If the BARO sensor output voltage is equal to or lower than a specified value, the ECM detects a malfunction and stores the P1107 code. In simpler terms, this fault code indicates that there is a low voltage issue with the Barometric Pressure sensor circuit.

This can affect the accuracy of the intake airflow estimation, potentially leading to performance issues in the vehicle. It is important to address this issue promptly to ensure optimal engine performance and fuel efficiency.

What are the possible causes of fault code P1107 in an automobile?

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 P1107 could be the culprit. This code is often caused by an outdated or incorrect software in the Engine Control Module (ECM), or a faulty ECM itself. To fix this issue, start by visually inspecting the wiring harness and connectors. Look out for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix fault code P1107?

To fix fault code P1107, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify any issues with the engine control module (ECM) or outdated/incorrect software. Don’t forget to check the “Possible Causes” listed above for a comprehensive solution.

What should I look for when checking for damaged components or corroded connector pins to resolve fault code P1107?
