The P0105, P0106, P0107, P0108, and P0109 codes all indicate some kind of issue with the Manifold Absolute Pressure sensor, which is also called the MAP sensor, the Barometric Pressure Sensor, or the Baro Sensor. This sensor measures your intake manifold pressure or atmospheric pressure. This reading is an important part of the calculations that the powertrain control module (PCM) or engine control module (ECM) makes in your vehicle to ensure smooth operation, as well as strong performance and good fuel economy. These codes indicate that your MAP sensor circuit is malfunctioning in some way, usually related to issues with signal voltage.
What Are the Symptoms of a P0106 Code?
The main symptom that most people will notice with the P0105, P0106, P0107, P0108, and P0109 codes is that the check engine light will turn on. It’s possible in some cases for that to be the only symptom. However, you may also notice issues with a rough-running engine, excessive exhaust pipe smoke, generally difficult handling and acceleration, poor idling, and an overall worse fuel economy. In some cases, you may even experience backfiring.
What Are Some Causes of a P0106 Code?
Many issues can result in the P0105, P0106, P0107, P0108, and P0109 codes, and many of these problems don’t have anything to do with the MAP sensor itself. On top of an actual problem with the MAP sensor, such as a defective sensor and shorted wiring, here are a few of the other issues that can result in one of these codes:
- Air intake system vacuum leak
- General issues with the air intake system
- Wiring concerns outside of the MAP sensor
- Clogged catalytic converter
- Severe or prolonged misfiring issues
- Defective throttle position sensor
- Faulty Mass Airflow Sensor
- Defective Exhaust Gas Recirculation valve
- Faulty Idle Air Control Motor
As you can see, there are a wide array of potential P0105, P0106, P0107, P0108, and P0109 code causes, which can complicate the process of fixing it. Checking for other error codes is an important part of fixing this problem.
How Serious Is the P0106 Code?
The P0105, P0106, P0107, P0108, and P0109 codes are definitely quite serious. Even though these codes simply indicate a potential concern with the MAP sensor circuit, that circuit helps your sensors create accurate readings that it then delivers to the PCM. These problems can result in issues with running smoothly, excessive fuel consumption, and general poor engine performance, including backfiring, which is quite a severe concern. You should treat these codes as quite serious and get help with them as soon as possible.
Can I Still Drive with a P0106 Code?
You should definitely avoid driving when your vehicle is showing the P0105, P0106, P0107, P0108, and P0109 codes. In most cases, you will physically be able to drive the vehicle, but continuing to drive increases your risk of effects that can harm the well-being of your engine. Even if you’re not currently seeing drivability problems with these codes, you should still avoid driving with them if possible.
How Easy Is It to Diagnose a P0106 Code?
Diagnosing the P0105, P0106, P0107, P0108, and P0109 codes is in fact exceptionally difficult. This is one of the more complex issues that can arise in a vehicle, simply due to how many underlying problems can cause the concern. Ruling out many of these problems can be time-consuming, difficult, and complex, and they may require specialized tools that most DIYers don’t have access to. A professional will help you diagnose these codes more effectively.
How Difficult Is It to Inspect a P0106 Code?
The inspection process for these codes is also frequently difficult. When you’re inspecting the P0105, P0106, P0107, P0108, and P0109 codes, you’re not just going to inspect the MAP sensor and the surrounding areas, but also many other components within the vehicle. This is difficult in any vehicle, but it’s also often individualized for each make and model. An expert has trained to do this as effectively as possible, but DIYers haven’t, which is why seeking a professional is so beneficial.
Need Additional Help with Your P0106 Code?
Most people will need additional help with these codes. If you’re looking for help with the P0105, P0106, P0107, P0108, and P0109 codes, there are plenty of ways that you can get the expert assistance you’re looking for.
First of all, you can find an auto repair shop in your area with KBB. It’s best to avoid driving your vehicle as much as possible when these codes are active, so looking for a local repair shop allows you to minimize your travel distance.
It’s also helpful for many people to use a code scanner to determine what other problems your vehicle has already highlighted. The OBD-II database at KBB will give you more insight into the issues that arise with other error codes, and this can help you understand the underlying cause of the problem even before you bring the vehicle in to an expert.
