P1107 code definition

The P1107 code is a manufacturer-specific powertrain code related to fuel and air metering. In this case, it means that the engine control module (ECM) has detected a low voltage signal from the barometric pressure sensor.

Codes related to the P1107 include:

What the P1107 code means

A code P1107 will be stored when the ECM receives a low voltage signal from the Barometric Pressure (BARO) sensor, which is built into the ECM and is used to monitor atmospheric pressure.

Manufacturers each may have different details and diagnosis/repair information depending on the affected make and model. Some automakers that have a manufacturer specific P1107 code include Acura, Audi, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Honda, Hyundai, Isuzu, Jaguar, Jeep, Kia, Lincoln, Mercury, Subaru, Suzuki, and Volkswagen.

What causes the P1107 code?

Several problems may cause a P1107 code including:

What are the symptoms of the P1107 code?

Symptoms of a P1107 code may include:

  • Check engine or warning light may illuminate
  • Vehicle may idle roughly
  • Engine may hesitate
  • Decrease in fuel economy

How does a mechanic diagnose the P1107 code?

A mechanic may use several methods to diagnose a P1107 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P1107 trouble code
  • Visually inspect electrical wiring and related connectors for damage or corrosion
  • Check to see if there is a malfunction in the MAF/BPS system circuitry
  • Check to see if unmetered air is entering the engine
  • Check if there is sufficient airflow to the engine
  • Check for clogged air filter
  • Check for a damaged or defective air inlet pipe
  • Check for a clogged catalytic converter
  • Check for any vacuum leaks
  • Check for power and ground at the barometric pressure and manifold air pressure sensors
  • Check the sensors against manufacturer recommendations for proper operation (hertz)

How serious is the P1107 code?

Because a vehicle’s safe driving operation most likely will be not impacted due to faults that store a P1107 code, this code is not considered potentially serious. When this code appears, it is recommended to take your vehicle to your local service center or mechanic for repair and diagnosis as soon as possible.

What repairs can fix the P1107 code?

Several repairs can fix a P1107 trouble code and include:

  • Repair any damaged or corroded wiring and related electrical connectors
  • Replace clogged or defective filters
  • Repair damaged or defective air inlet pipe
  • Repair any vacuum leaks or replace vacuum hoses
  • Replace damaged or defective manifold absolute pressure sensor
  • Replace damaged or defective barometric pressure sensor
  • Replace and reprogram damaged or defective ECM
  • Clear all codes, test-drive the vehicle, and rescan to see if any codes reappear

It is always recommended to diagnose trouble codes in the order in which they are stored. Mass airflow, manifold air pressure, or engine misfire codes, if present, should be diagnosed and repaired prior to diagnosing and repairing a P1107 trouble code.
