Code P0107 Description and Causes
When your vehicle’s onboard computer generates a P0107 code, it’s indicating a problem with the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit, which provides essential data to the engine control module (ECM).
This issue can be caused by sensor failure, resulting in incorrect pressure readings. Pressure fluctuations can also lead to a low input signal, triggering the P0107 code.
Other possible causes include wiring or connector issues, vacuum leaks in the intake system, or a clogged air filter.
Addressing this issue promptly is pivotal to prevent further engine damage and performance issues.
Symptoms of P0107
Your vehicle’s engine performance will likely suffer if a P0107 code is triggered, and you may notice some telltale signs.
You might experience rough idling patterns, accompanied by engine hesitation when accelerating or decelerating. This can lead to decreased engine power, making it difficult to maintain speed or climb hills.
Additionally, your fuel efficiency may suffer, and you might notice your engine stalling or struggling to start. The illuminated Check Engine Light will also be a clear indication that something’s amiss.
These symptoms can be frustrating, but addressing the underlying issue will help restore your vehicle’s performance and prevent further damage.
How to Fix P0107
To fix a P0107 code, start by inspecting the MAP sensor and BARO sensor for signs of damage or corrosion.
This is a vital step in identifying the root cause of the issue.
- Check the wiring and connectors for any loose connections or frayed wires that could be affecting the sensor’s performance.
- Perform sensor calibration to verify the MAP sensor is providing accurate readings.
- Test the vacuum system for leaks and repair as necessary to prevent incorrect fuel delivery.
- Consult your engine troubleshooting guide for specific procedures related to your vehicle’s make and model.
- Clear the DTC and test drive the vehicle to verify the issue has been resolved.
Cost to Fix P0107 and Tech Notes
Typically, the cost to fix a P0107 code can range from $100 to $300, depending on the extent of the repairs needed. This estimate includes labor costs, which can vary depending on the auto repair shop’s rates.
| Repair Component | Repair Estimate | Diagnostic Challenges |
|---|---|---|
| MAP Sensor Replacement | $50-$150 | Faulty sensor diagnosis |
| Wiring Repair | $20-$50 | Locating wiring issues |
| Vacuum System Repair | $30-$100 | Identifying vacuum leaks |
| ECM Malfunction | $50-$200 | Advanced diagnostic tools required |
Keep in mind that these estimates are rough and may vary depending on your location and the shop’s rates.
Understanding the MAP Sensor
The Manifold Absolute Pressure (MAP) sensor is a critical component in modern fuel-injected engines, responsible for monitoring the pressure inside the intake manifold and providing this data to the Engine Control Module (ECM).
You’ll find the MAP sensor mounted on the intake manifold or connected to it via a hose. Its sensor function is to measure the pressure readings inside the intake manifold, which helps the ECM determine the correct air/fuel mixture for ideal engine performance.
- The MAP sensor provides real-time pressure data to the ECM.
- This data is used to adjust fuel injection timing and duration.
- The sensor’s output voltage signal corresponds to the pressure readings.
- A faulty MAP sensor can cause incorrect fuel delivery and poor engine performance.
- The ECM uses the MAP sensor data to calculate engine load and adjust ignition timing.
Common Causes of P0107
When your vehicle throws a P0107 code, it’s essential to identify the root cause of the issue to guarantee a proper repair.
Sensor failure is a common culprit, with the MAP sensor being a prime suspect. Wiring issues, such as frayed or corroded connections, can also cause the code.
Other potential causes include vacuum leaks in the intake system, a clogged air filter, and ECM malfunction.
It’s vital to address these issues promptly to prevent further damage to your engine. By understanding the common causes of P0107, you can take the first step towards a successful repair.
Diagnosing and Repairing the Issue
To diagnose the P0107 code, start by inspecting the MAP sensor and BARO sensor for signs of damage, corrosion, or worn-out components.
This will give you a clear indication of whether the issue lies with the sensors themselves or if it’s further down the line.
- Use a scan tool to monitor the MAP sensor’s output and compare it to the BARO sensor’s reading.
- Perform a sensor cleaning to remove any debris or grime that may be affecting the signal.
- Check the wiring and connectors for any signs of damage or corrosion.
- Test the vacuum system to verify there are no leaks that could be causing the low input signal.
- Consult your repair manual for specific troubleshooting steps for your vehicle’s make and model.
Preventing Future Occurrences
Regular maintenance and inspections can help prevent future occurrences of the P0107 code. By staying on top of your vehicle’s upkeep, you can identify potential issues before they become major problems.
| Task | Interval | Purpose |
|---|---|---|
| Inspect MAP sensor | Every 30,000 miles | Check for signs of damage or corrosion |
| Replace air filter | Every 15,000 miles | Guarantee proper airflow to the MAP sensor |
| Check vacuum system | Every 60,000 miles | Identify and repair any leaks |
| Sensor calibration | As needed | Certify accurate readings from the MAP sensor |

Can I Drive My Car With a P0107 Code?
You can drive your car, but be aware that a low input signal from the MAP sensor can affect fuel efficiency and engine performance, leading to rough idling, stalling, and decreased power, so it’s recommended to address the issue as soon as possible.
Will a P0107 Code Cause My Car to Fail an Emissions Test?
Imagine your car’s engine as a well-oiled machine; a P0107 code disrupts this harmony, affecting fuel efficiency and engine performance, making it likely to fail an emissions test, as pollutants increase due to incorrect fuel delivery.
Can a Clogged Catalytic Converter Trigger a P0107 Code?
You’re wondering if a clogged catalytic converter can trigger a P0107 code. While it’s unlikely, a severely clogged converter can increase exhaust pressure, which may affect manifold absolute pressure, potentially leading to a low input signal and a P0107 code.
Will a P0107 Code Reset Itself if the Issue Is Fixed?
You’ll be surprised to know that 90% of faulty sensors can be cleaned and restored! If you’ve fixed the underlying issue, you’ll likely need to clear the code manually, as the engine computer won’t reset it automatically, especially if it’s related to pressure fluctuations in the MAP sensor circuit.
Can a Faulty Oxygen Sensor Cause a P0107 Code?
