One of the most common codes that Chevy owners encounter is the P0106 engine code, which can indicate a problem with the manifold absolute pressure (MAP) sensor.
If your car check engine light comes on and you see this diagnostic trouble code on your Chevy's dashboard, don't panic.
In this article, we'll dive deep into what the P0106 code in Your Chevy means, the possible causes, and the solutions to fix it. By the end, you'll better understand your car's health and how to keep it running smoothly.

Common Causes of the P0106 Code
Faulty or dirty MAP sensor
This specific sensor measures the intake manifold pressure and sends this message to the engine control module (ECM). If the sensor is dirty and/or malfunctioning, it may send incorrect readings to the ECM, causing the P0106 code to appear.
Wiring or Connection Issues
The wiring and connections that link the MAP sensor to the ECM can also cause the P0106 code to appear. Loose, corroded, or damaged wires or connections can interfere with the signal transmission between the MAP sensor and the ECM, leading to erroneous data.
Vacuum leaks can cause a reduction in pressure inside the intake manifold, leading to inaccurate readings by the MAP sensor. This can trigger the P0106 code.
Clogged or Dirty Air Filter
A dirty or clogged air filter can impact the airflow to the engine, which can, in turn, cause a drop in pressure inside the intake manifold. This can also cause the P0106 code to appear.
Failed PCM or ECM
Although rare, a malfunctioning PCM or ECM can also trigger the P0106 code. This is usually the last resort after all other potential causes have been ruled out
It's essential to note that these are just some of the possible causes of the P0106 code in your Chevy. A proper diagnosis by a qualified mechanic is necessary to pinpoint the underlying issue accurately.
How a Professional Mechanic Diagnoses the P0106 Code
When a Chevy owner brings their vehicle to a mechanic with a P0106 code, the mechanic will perform a series of diagnostic tests to identify the root cause of the issue.
Here are the steps a professional mechanic typically follows when diagnosing the P0106 code:
The mechanic will begin by visually inspecting the vacuum hoses, wiring, and connectors around the MAP sensor to see if there are any signs of damage or wear.
Scan Tool Diagnosis
The certified mechanic will use a scan tool to read the trouble codes stored in the ECM and access live data from the MAP sensor. This allows them to determine if the MAP sensor is sending accurate readings to the ECM.
MAP Sensor Testing
If the scan tool indicates that the MAP sensor is not sending accurate readings, the mechanic will remove the sensor from the engine and test it with a digital multimeter. This will determine if the sensor is faulty and needs to be replaced.
Vacuum System Inspection
If the MAP sensor is functioning correctly, the mechanic will inspect the vacuum system for leaks or blockages that could affect the pressure in the intake manifold.
Air Filter Inspection
Finally, the mechanic will inspect the air filter to see if it's dirty or clogged, which could limit the airflow to the engine and cause a drop in pressure inside the intake manifold.
Once the root cause of the P0106 code has been identified, the mechanic will perform the necessary repairs to fix the issue. This could include replacing the MAP sensor, repairing or replacing damaged wiring or connectors, fixing vacuum leaks, or replacing the air filter.
The P0106 code is a standard trouble code that many Chevy owners encounter. It can indicate an issue with the MAP sensor, wiring, vacuum system, or air filter. Most of these issues can be resolved quickly and easily by a qualified mechanic using Goodhood's mobile auto repair service.
If you are experiencing this code in your Chevy, don't hesitate to book a Goodhood technician immediately. Sometimes this could be the only code present, or there could be more issues. So it's best to have our ASE-certified technicians diagnose your vehicle so you can get back on the road as quickly as possible.
Frequently Asked Questions
What does the P0106 code mean?
The P0106 code indicates that there is an issue with the manifold absolute pressure (MAP) sensor. It could be caused by a faulty or dirty MAP sensor, wiring or connection issues, vacuum leaks, clogged or dirty air filters, or a failed PCM or ECM.
How do I fix the P0106 code?
The best way to fix the P0106 code is to have a qualified mechanic diagnose and repair it. With Goodhood's mobile auto repair service, you can book a technician to come directly to your location and diagnose your car's issue. Once the root cause has been identified, they can then perform the necessary repairs to get your car back up and running.
Is the powertrain control module involved in the P0106 code?
The powertrain control module (PCM) is not directly affected by the P0106 code, but it could be damaged or malfunctioning if all other potential causes have been ruled out. In this case, replacing the PCM may be necessary to resolve the issue.
What does the engine load pressure sensor do?
The engine load pressure sensor also known as the manifold absolute pressure, or MAP, sensor) measures the air pressure inside the intake manifold. This information is sent to the car engine control module (ECM), which uses it to adjust the fuel and air mixture for optimum performance. If there is an issue with this sensor, it can cause the P0106 code to appear.
What will a mechanic do to diagnose the P0106 code?
The mechanic will use a scan tool to read any trouble codes stored in the engine control module (ECM), test the MAP sensor, inspect the vacuum system for leaks or blockages, and inspect the air filter to ensure it's not clogged or dirty. Once they have identified the root cause of the issue, they can then perform the necessary repairs to fix it.
What will happen if I ignore the P0106 code?
Ignoring the P0106 code can further damage your engine and other vehicle components. It's important to diagnose and repair it as soon as possible to prevent any future issues.
