How to Fix Code P0107 – A Step-By-Step Guide

AvatarByCarl Frisch

Code P0107 is a generic powertrain diagnostic trouble code (DTC) indicating an issue with the manifold absolute pressure (MAP) sensor circuit. This code is typically triggered when the MAP sensor sends an abnormal voltage signal to the engine control module (ECM).

To fix this issue, start by checking for any loose or damaged wiring in the MAP sensor circuit. Check for any open or short circuits in the wiring and repair as needed. If there are no issues with the wiring, then check to make sure that there is no vacuum leak in the intake manifold. If a vacuum leak is present, it will need to be repaired before the code can be cleared and engine operation returned to normal.

Once wiring and vacuum leaks have been addressed, clear any codes present within the ECM and test drive vehicle to see if code returns. If code returns, then replace MAP sensor and retest drive vehicle. After replacement of MAP sensor, clear codes again and retest drive vehicle to make sure that code does not return.

What is Code P0107?

Code P0107 is a diagnostic trouble code (DTC) for an issue with the intake manifold pressure sensor. This code is often associated with a decrease in engine performance, as well as illumination of the check engine light. This code can be extremely difficult to diagnose and fix since the cause of the issue can be related to a variety of different components.

Symptoms of Code P0107

Some of the most common symptoms associated with this code include decreased engine performance, illumination of the check engine light, and possibly stalling or misfiring. It is important to note that not all vehicles will experience these symptoms, and some may only experience one or two of them.

Causes of Code P0107

There are several potential causes for this code, but some of the most common include problems with the intake manifold pressure sensor, vacuum lines or hoses, and electrical connection issues. It is also possible that fuel system issues may be causing this code, so it is important to inspect all related components before starting repairs.

Diagnosing and Fixing Code P0107

In order to properly diagnose and fix this code, there are certain tools and steps that must be taken. The first step is to diagnose which component is causing the error by inspecting each relevant part for signs of wear or damage. If any worn parts are found, they should be replaced immediately before moving on to other potential solutions.

Tools Needed To Diagnose And Fix The Error

In order to correctly diagnose and fix this error code, certain tools must be used. These include an OBD-II scanner (to read codes from your vehicle’s computer), a multimeter (to measure voltage and resistance), a vacuum gauge (to measure vacuum levels in various parts), and various other specialty tools depending on which components need to be inspected or replaced.

Steps To Diagnose And Fix The Error

The first step in diagnosing and fixing this error is to read any codes stored in your vehicle’s computer using an OBD-II scanner. Once you have determined which code(s) were present at the time of diagnosis, you can begin inspecting relevant components for signs of wear or damage. If any worn parts are found, they should be replaced immediately before moving on to other solutions. If no worn parts are found, then you can move on to checking electrical connections for any loose wires or corroded connectors that may need cleaning or replacing. You should also check vacuum lines and hoses for any cracks or leaks that could cause an issue with proper air flow into the engine compartment. Finally, if all else fails you can try resetting your vehicle’s computer by disconnecting its battery for 30 minutes before reconnecting it again – this will erase any codes stored in its memory and allow you to start fresh when diagnosing your issue again if needed.

Common Problems That Can Cause The Code P0107 Error

There are several common problems that can cause this error code including issues with the intake manifold pressure sensor, vacuum lines/ hoses, electrical connections and fuel system issues. In order to determine which problem is causing your car’s issue it is important to inspect each component thoroughly before starting repairs.

Intake Manifold Pressure Sensor Issues

One common problem associated with this error code is an issue with the intake manifold pressure sensor itself – either due to it being faulty or due to clogged air filter(s) restricting air flow into it resulting in incorrect readings being sent back from it.

Code P0107

Code P0107 is a diagnostic trouble code (DTC) for “Manifold Absolute Pressure/Barometric Pressure Circuit Low Input”. This code typically appears when the pressure in the intake manifold has become too low. It usually indicates an issue with the Mass Air Flow (MAF) sensor, but can also indicate an issue with the MAP sensor, vacuum leaks, or intake air leaks.

Causes of Code P0107

The most common cause of this code is a dirty or faulty MAF sensor. The MAF sensor measures the amount of air flowing into the engine and helps to regulate fuel mixture. If it becomes clogged or contaminated, it can cause false readings and trigger this code. Other possible causes include:

– A faulty MAP sensor
– A vacuum leak
– An intake air leak
– Damaged wiring or connectors
– An issue with the intake manifold itself
– A faulty throttle body
– An exhaust system leak
– Corroded connectors on the MAF sensor or MAP sensor

Diagnosing Code P0107

The first step in diagnosing this code is to check for any other codes that may be present. If other codes are found, they should be addressed before attempting to diagnose this one. Once any other codes have been cleared, you should then begin by inspecting all wiring and connectors related to the MAF and MAP sensors. Check for any damage or corrosion that may be present and repair as needed.

Next, you should check for any vacuum leaks in the intake system by using a can of carburetor cleaner and spraying it around each connection while listening for changes in engine idle speed. Any leaks should be repaired before continuing with diagnosis. You should also inspect all of the hoses going to and from the intake manifold for signs of damage or wear which could lead to an air leak. Finally, you should inspect all other components such as the throttle body and exhaust system for signs of damage or wear that could cause this code to appear.

Fixing Code P0107

Once all components have been inspected for damage, it’s time to start replacing parts if necessary. The first part that you will want to replace is usually going to be either the MAF or MAP sensors depending on which component has been identified as having an issue during diagnosis. After replacing either component you will need to clear all stored codes from your vehicle’s computer in order for them to reset themselves properly and begin operating correctly again. Depending on your make and model, this may require special tools such as a scanner or diagnostic tool in order to complete successfully.

If no issues were identified during diagnosis then it’s likely that there is an issue with either your vehicle’s computer itself or with its programming software which could require professional assistance in order to resolve properly. It’s also important to note that if there are any signs of damage or wear on any other components such as hoses going into your intake manifold then they should also be replaced before attempting to clear any stored codes from your vehicle’s computer as doing so without replacing these parts can often lead to further issues down the line if left unchecked.
