P0107 2016 GMC Sierra Code - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0107 2016 GMC Sierra Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAP Sensor voltage is less than 0.15 V for greater than 13 ms.
What are the Possible Causes of the DTC P0107 2016 GMC Sierra?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P0107 2016 GMC Sierra Code
What does the P0107 code mean on a 2016 GMC Sierra?
The P0107 code indicates that the Manifold Absolute Pressure (MAP) sensor is reporting a voltage signal that is too low, which could affect engine performance.
What are common symptoms of the P0107 code in a GMC Sierra?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, difficulty starting, or the check engine light turning on.
What causes the P0107 code to appear?
Common causes include a faulty MAP sensor, damaged wiring or connectors, vacuum leaks, or issues with the vehicle’s engine control module (ECM).
Can I drive my GMC Sierra with a P0107 code?
While the vehicle may still be drivable, it’s not recommended, as prolonged driving with this code can lead to decreased performance and potential engine damage.
How do you fix the P0107 code on a 2016 GMC Sierra?
Repairs may involve replacing the MAP sensor, inspecting and repairing wiring or connectors, checking for vacuum leaks, or updating/replacing the ECM if necessary.
Where is the MAP sensor located on a 2016 GMC Sierra?
The MAP sensor is typically located on the intake manifold near the throttle body.
How can you test a MAP sensor for a P0107 code?
You can test a MAP sensor using a multimeter to measure voltage output or a scan tool to check live data for proper readings under various engine conditions.
Can a dirty throttle body cause a P0107 code?
Yes, a dirty throttle body can affect airflow and pressure readings, potentially contributing to a P0107 code.
How much does it cost to fix a P0107 code on a GMC Sierra?
Repair costs can vary but typically range from $100 to $300 for parts and labor, depending on whether the MAP sensor or other components need replacement.
Will clearing the P0107 code fix the problem?
Clearing the code may temporarily turn off the check engine light, but it won’t resolve the underlying issue causing the code. Proper diagnosis and repair are needed.
