P0107 Hummer 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 Hummer 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 Hummer?
- 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)
How to Fix the DTC P0107 Hummer?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0107 Hummer code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0107 Hummer Code
1. What are the common symptoms of OBDII code P0107 in a Hummer?
- Common symptoms include poor engine performance, reduced fuel efficiency, stalling, rough idling, and illuminated Check Engine Light.
2. What causes the Manifold Absolute Pressure/Barometric Pressure Circuit Low Input code in a Hummer?
- Possible causes include a faulty MAP sensor, damaged wiring or connectors in the MAP sensor circuit, intake manifold leaks, or a clogged air filter.
3. How can I diagnose the P0107 code in my Hummer?
- You can use an OBDII scanner to retrieve the trouble code, visually inspect the MAP sensor and its connections, perform a smoke test to check for intake manifold leaks, and test the sensor's voltage output.
4. Can I drive my Hummer with the P0107 code present?
- It is not recommended to drive your vehicle with the P0107 code as it can lead to further damage and poor engine performance. It is best to address the issue promptly.
5. How do I repair the Manifold Absolute Pressure/Barometric Pressure Circuit Low Input code in my Hummer?
- Repair options may include replacing the MAP sensor, repairing or replacing damaged wiring or connectors, fixing intake manifold leaks, and ensuring proper air filter maintenance.
6. Will resetting the trouble code make it go away permanently?
- Resetting the trouble code may temporarily turn off the Check Engine Light, but if the underlying issue is not fixed, the code is likely to reappear after driving a certain distance.
7. Is the P0107 code specific to Hummer vehicles?
- No, the P0107 code is a generic OBDII code related to a low input signal from the MAP sensor, and it can occur in various makes and models, including Hummer vehicles.
8. Can a dirty air filter trigger the P0107 code in a Hummer?
- Yes, a dirty or clogged air filter can disrupt airflow and affect the readings of the MAP sensor, potentially leading to the P0107 trouble code.
9. How long does it take to repair the P0107 code in a Hummer?
- The repair time can vary depending on the specific cause of the code. Simple fixes like replacing a sensor or cleaning a connector may take less than an hour, while more complex issues could take longer.
10. Should I attempt to diagnose and repair the P0107 code on my own?
- If you have the necessary tools, knowledge, and experience, you can attempt to diagnose and repair the P0107 code. However, if you are unsure or inexperienced, it is recommended to seek professional help to avoid further complications.

I disconnect the battery and removed the ECM connectors andECM pins clean them with circuit cleaner & put die electric grease on them . also clean the MAS connector as well cleared codes went out for awhile but its back with the same codes .
