Troubleshooting P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low

P0107 is a diagnostic trouble code (DTC) indicating an issue with the Manifold Absolute Pressure/ Barometric Pressure (MAP/BARO) circuit. This code is triggered when the MAP/BARO circuit voltage is lower than the expected value. This code can be caused by an electrical issue, such as a faulty MAP/BARO sensor, wiring, or connections; or due to a vacuum leak in the intake manifold. Diagnosing and repairing this issue requires testing of the MAP/BARO system and related components.

Automobile Manifold Pressure System

The manifold pressure system is an important part of an automobile’s engine, as it helps to measure the pressure inside the engine manifold and the barometric pressure outside of it. Comparing the two allows for a better understanding of how much air is entering and exiting the engine. This aids in controlling the fuel-air mixture, which helps to maintain optimal performance.

When there is a problem with this system, it can trigger an error code known as P0107. This code is related to a low voltage in the Manifold Absolute Pressure/Barometric Pressure (MAP/BARO) circuit. It can be caused by clogged air filters, faulty Mass Airflow Sensors (MAF), or vacuum leaks.

Diagnosing and Repairing the P0107 Error

In order to diagnose and repair this error code, it’s important to first troubleshoot the manifold pressure system. This involves checking all components related to it, such as intake hoses, valves, sensors, etc., for any signs of damage or malfunctioning. If any of these components are found to be defective or failing, they must be replaced with new parts or components in order to restore proper functioning of the system.

Preventative Maintenance Tips

In order to prevent future issues with this system and avoid triggering another P0107 error code, regular maintenance should be carried out on all parts related to it. This includes checking air filters and MAF sensors for blockages or any other signs of wear and tear; inspecting vacuum lines for any leaks or tears; and replacing worn-out parts as soon as possible. Doing so will help keep your vehicle running smoothly and efficiently.

Exploring Alternative Solutions for P0107 Error

In some cases, resetting the ECU may clear the P0107 error code without needing further troubleshooting or repairs. This can be done using an OBD-II scan tool by disconnecting its power source from the battery for 30 minutes before reconnecting it again. However, if this doesn’t work then further investigation may be necessary in order to identify and rectify any underlying issues with the manifold pressure system that may have caused it in the first place.

Benefits of Regular Automobile Maintenance

Regular automobile maintenance is essential for the proper functioning of your vehicle and can provide you with significant savings in the long run. Proper maintenance will help to ensure that your car runs smoothly, efficiently and safely. Regular tune-ups, oil changes, filter replacements and brake inspections can all help to extend the life of your vehicle and improve its performance.

In terms of improved performance, properly maintained vehicles are more fuel efficient than those that are not regularly serviced. This means that you can save money on your gas bills each month. In addition, regular maintenance can help to ensure that small issues are addressed before they become major problems. This can save you a significant amount of money in repairs or replacements down the road.

Potential Hazards of Ignoring Auto Maintenance Issues

Unfortunately, ignoring auto maintenance issues can lead to a number of potential hazards for drivers. Failing to address existing problems with your vehicle could increase the risk of breakdowns and accidents on the road. This is especially true if there is an issue with critical components such as brakes or steering systems.

In addition, neglecting regular auto maintenance could result in higher costs down the line as small issues may become larger ones if not addressed in a timely manner. For example, a small oil leak may be manageable but if left unchecked it could turn into a major engine problem requiring expensive repairs or replacements.


In conclusion, regular automobile maintenance is essential for ensuring safe operation of your vehicle and maximizing its performance and efficiency over time. Ignoring auto maintenance issues can increase the risk of breakdowns and accidents, as well as lead to costly repairs later on down the line. Therefore, it is important to stay up-to-date with all scheduled service appointments in order to keep your car running smoothly for years to come!

Q: What is the P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Error?
A: The P0107 error is a fault code that indicates an issue with the vehicle’s Manifold Absolute Pressure (MAP) and Barometric Pressure (BARO) circuits. This code may be triggered when the MAP sensor is not reading the correct pressure or when the BARO sensor is not providing enough pressure to the engine.

Q: What are Common Causes of P0107 Errors?
A: Common causes of P0107 errors include clogged air filters, faulty mass airflow sensors, and vacuum leaks.

Q: How Can I Diagnose and Repair the P0107 Error?
A: When diagnosing a P0107 error, it is important to first troubleshoot the Manifold Pressure System to identify any potential issues. If any faulty parts or components are identified, they should be replaced according to manufacturer specifications.

Q: What are some Preventative Maintenance Tips for Avoiding Auto Maintenance Issues?
A: Regular maintenance of your automobile can help prevent costly repairs down the line. Some preventative maintenance tips include regularly checking air filters and mass airflow sensors, as well as frequently inspecting vacuum lines for leaks or damage.

Q: Are there Alternative Solutions for Dealing with a P0107 Error?
A: Yes, there are alternative solutions that can be used to deal with a P0107 error. These include resetting the ECU to clear codes and using an OBD-II scan tool for troubleshooting.

The p0107 manifold absolute pressure/barometric pressure circuit low can cause major problems for an automobile. It is important to diagnose this issue as soon as possible, as it can lead to a decrease in fuel efficiency and even engine stalling if left unchecked.
