P0107 2014 Chevrolet Silverado 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 2014 Chevrolet Silverado 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 2014 Chevrolet Silverado?
- 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)

2. What are the common symptoms of code P0107 in a 2014 Chevrolet Silverado?
Symptoms may include poor engine performance, rough idling, stalling, reduced fuel efficiency, or the check engine light turning on.
3. What causes the P0107 code on a 2014 Chevrolet Silverado?
Common causes include a faulty MAP sensor, damaged or corroded wiring, a vacuum leak, or a failing ECM.
4. Can a dirty air filter cause a P0107 code?
A dirty air filter is unlikely to cause a P0107 code, but it’s still important to ensure the air intake system is clean and functioning properly as part of the diagnostic process.
5. How do I diagnose the P0107 code on my 2014 Chevrolet Silverado?
Start by inspecting the MAP sensor and its wiring for damage or corrosion. Check for vacuum leaks and use a multimeter to test the sensor’s voltage output.
6. Can I drive my 2014 Chevrolet Silverado with a P0107 code?
Driving with a P0107 code is not recommended, as it can lead to poor engine performance or potential damage if the issue worsens.
7. How do I fix the P0107 code on a 2014 Chevrolet Silverado?
Repairs may include replacing the MAP sensor, repairing or replacing damaged wiring, fixing vacuum leaks, or reprogramming/replacing the ECM if necessary.
8. How much does it cost to fix a P0107 code on a 2014 Chevrolet Silverado?
The cost can vary, but replacing a MAP sensor typically costs $50 to $200, while wiring repairs or ECM replacement may cost significantly more depending on the extent of the issue.
9. Can a bad MAP sensor affect fuel economy on a 2014 Chevrolet Silverado?
Yes, a faulty MAP sensor can cause incorrect fuel-air mixture calculations, leading to reduced fuel efficiency.
10. What tools are needed to troubleshoot a P0107 code?
You’ll need an OBDII scanner, a multimeter, and possibly a vacuum gauge to diagnose the issue accurately.
