P0106 2015 GMC Sierra Code - Manifold Absolute Pressure Performance
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 P0106 2015 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 determines the MAP Sensor is stuck within the normal operating range. It accomplishes this by running 3 different models within the software to determine the values.
What are the Possible Causes of the DTC P0106 2015 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 P0106 2015 GMC Sierra Code
What does the OBDII code P0106 mean on a 2015 GMC Sierra?
1. P0106 indicates a problem with the Manifold Absolute Pressure (MAP) sensor, specifically a performance or range issue, meaning the sensor is providing readings that are inconsistent or out of range. 2.
What are the common symptoms of a P0106 code in a 2015 GMC Sierra?
Symptoms may include poor engine performance, rough idling, stalling, reduced fuel efficiency, difficulty starting, and the check engine light turning on. 3.
What causes the P0106 code to appear in a 2015 GMC Sierra?
Common causes include a faulty MAP sensor, vacuum leaks, damaged wiring or connectors, a clogged air filter, or intake manifold issues such as blockages. 4.
Can a dirty air filter trigger a P0106 code on a 2015 GMC Sierra?
Yes, a dirty or clogged air filter can restrict airflow, leading to inaccurate readings from the MAP sensor and triggering the P0106 code. 5.
How do you diagnose a P0106 code on a 2015 GMC Sierra?
Diagnosis typically involves checking the MAP sensor and its wiring for damage, inspecting for vacuum leaks, verifying the intake manifold for blockages, and using a scan tool to monitor sensor readings. 6.
Is it safe to drive a 2015 GMC Sierra with a P0106 code?
While the vehicle may still be drivable, it is not recommended to ignore the code, as it can lead to reduced performance, increased fuel consumption, and potential engine damage if the underlying issue is not resolved. 7.
How do you fix a P0106 code on a 2015 GMC Sierra?
Repairs may involve replacing the MAP sensor, repairing damaged wiring or connectors, fixing vacuum leaks, cleaning or replacing the air filter, and ensuring the intake manifold is clear. 8.
Can a bad MAP sensor cause engine stalling in a 2015 GMC Sierra?
Yes, a faulty MAP sensor can cause incorrect air-fuel mixture readings, leading to engine stalling and poor performance. 9.
What tools are needed to fix a P0106 code on a 2015 GMC Sierra?
You may need a scan tool, a multimeter for testing the sensor and wiring, basic hand tools, and potentially a vacuum gauge to check for leaks. 10.
Can an exhaust leak cause a P0106 code on a 2015 GMC Sierra?
While not a common cause, an exhaust leak near the manifold could potentially affect MAP sensor readings, though it is more likely related to intake or sensor-specific issues.
