Code P1107 GMC Description
The P1107 GMC code indicates an issue with the Manifold Absolute Pressure (MAP) sensor circuit, specifically intermittent low voltage. The MAP sensor is a crucial component of the engine management system, as it measures the air pressure inside the intake manifold. This information is used by the Engine Control Module (ECM) to calculate the correct air-fuel mixture for combustion. When the voltage from the MAP sensor falls below the specified threshold intermittently, it can lead to various performance issues in the vehicle.
Common Causes of P1107 GMC
- Faulty MAP sensor
- Damaged wiring or connectors in the MAP sensor circuit
- Vacuum leak in the intake manifold
- ECM malfunction
- Poor electrical connection
Symptoms of P1107 GMC
- Rough idling
- Hesitation or stumbling during acceleration
- Reduced power
- Stalling
- Decreased fuel efficiency
How to Fix P1107 GMC
- Begin by inspecting the wiring and connectors in the MAP sensor circuit for any visible damage. Repair or replace as necessary.
- Test the MAP sensor using a multimeter to ensure it is functioning within the specified voltage range. Replace the sensor if it is faulty.
- Check for any vacuum leaks in the intake manifold and repair them.
- Clear the diagnostic trouble codes from the ECM and reset the system.
- Perform a test drive to verify that the issue has been resolved and that the vehicle is operating smoothly.
Cost to Fix P1107 GMC
The cost of repairing a P1107 GMC code can vary depending on the specific cause of the issue and the labor rates in your area.
