Code P0107 Hummer Description
The P0107 diagnostic trouble code (DTC) for Hummer vehicles refers to an issue with the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit having a low input signal. The MAP sensor is crucial for the engine control unit (ECU) to determine the air pressure and density in the intake manifold, which allows for the calculation of the correct air-fuel mixture for combustion. The BARO sensor, on the other hand, helps the ECU adjust for changes in atmospheric pressure.
Common Causes of P0107 Hummer
- Faulty MAP sensor
- Faulty BARO sensor
- Wiring or connector issues
- Vacuum leak in the intake system
- Clogged or dirty air filter
Symptoms of P0107 Hummer
- Poor fuel economy
- Rough idling or stalling
- Hesitation or stumbling during acceleration
- Lack of power
- Increased emissions
How to Fix P0107 Hummer
- Begin by thoroughly inspecting the MAP and BARO sensors, their wiring, and connectors for any visible damage or corrosion.
- Test the sensors using a multimeter to ensure they are functioning within the manufacturer's specifications.
- Check for any vacuum leaks in the intake system and repair as necessary.
- Replace the air filter if it is clogged or dirty.
- If the issue persists, consult a professional mechanic for further diagnostics and potential ECU testing or replacement.
Cost to Fix P0107 Hummer
The typical repair costs for addressing a P0107 code in a Hummer vehicle can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnosis time and labor rates can vary, so it's recommended to obtain quotes from local auto repair shops for a more accurate estimate.

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.
