Code P1107 Buick Description

The P1107 Buick code indicates a problem with the Manifold Absolute Pressure (MAP) Sensor Circuit, with intermittent low voltage being detected. The MAP sensor is a crucial component of the engine management system, as it measures the pressure inside the intake manifold and provides this information to the engine control module (ECM). This data helps the ECM determine the correct air-fuel mixture for optimal engine performance.

How to Fix P1107 Buick

  1. Diagnose the issue by using a scan tool to verify the P1107 code and check the MAP sensor's voltage readings.
  2. Inspect the MAP sensor and its wiring for any visible damage or corrosion. Replace the sensor if necessary.
  3. Test the MAP sensor's voltage output using a multimeter to ensure it is within the manufacturer's specifications.
  4. Check for vacuum leaks in the intake manifold and repair as needed.
  5. Clear the trouble code from the ECM's memory and perform a test drive to verify that the issue has been resolved.

Cost to Fix P1107 Buick

The cost of repairing a P1107 Buick code can vary depending on the specific cause of the issue. In general, replacing a faulty MAP sensor can cost between $100 and $200, including parts and labor. However, if additional repairs or diagnostics are needed, such as fixing wiring issues or addressing vacuum leaks, the total cost may increase. It is recommended to consult with a professional mechanic or dealership for a more accurate estimate based on the specific circumstances of your vehicle. Keep in mind that labor rates and part prices can vary based on location and the vehicle's make and model.

When is the Code Detected?

If the Powertrain Control Module (PCM) detects a Manifold Absolute Pressure (MAP) sensor signal voltage that is intermittently low, the P1107 code will set.
