Vehicle engine and/or automatic transmission
Code: P0106 - Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance

Specifically, the P0106 code indicates a problem with the range or performance of this sensor circuit, meaning that the readings from the sensor are outside the expected range or not performing as they should. This issue can lead to engine performance problems if left unchecked.

The P0106 code is a common issue in Chevrolet vehicles, particularly in models such as the Chevrolet Aveo, Cruze, Silverado, Equinox, Epica, Lacetti and Malibu. These vehicles tend to experience issues with the MAP or barometric pressure sensor circuit due to the way their sensor systems are designed. Over time, these systems can become more prone to electrical interference, sensor failure, or wear on the wiring, which can trigger the P0106 error code.

❗ If you own one of these Chevrolet models, it’s important to regularly inspect the MAP sensor, vacuum hoses, and wiring to prevent the P0106 error code from appearing. Taking proactive measures will help maintain your vehicle’s engine performance and efficiency.

What Causes the P0106 Code?

The P0106 code is triggered when the Manifold Absolute Pressure (MAP) or Barometric Pressure sensor is not performing as expected. The ECU compares the readings from the sensor against a set range, and when these readings fall outside that range, the code is thrown. Some of the most common causes for this include:

  • Faulty MAP sensor: If the MAP sensor itself is malfunctioning or damaged, it may send incorrect data to the engine control unit.
  • Vacuum leaks: A vacuum leak can interfere with pressure readings, causing them to fall outside of the expected range.
  • Damaged wiring or connections: Wiring issues, such as frayed or disconnected wires, can affect the signal sent to the ECU, leading to performance issues.
  • Dirty or clogged sensors: Over time, dust, dirt, or oil can build up on the sensor, causing incorrect readings.
  • Faulty barometric pressure sensor: In some cases, the barometric pressure sensor may also be at fault if it’s not measuring air pressure correctly.

Any of these issues can lead to an inaccurate sensor reading, triggering the P0106 code.

Symptoms of the P0106 Code

If your vehicle’s computer detects a problem with the MAP or barometric pressure sensor circuit, the P0106 error code will trigger. Here are the most common symptoms associated with this code:

  • Illuminated check engine light (CEL)
  • Engine rough idle or stalling
  • Decreased engine performance, especially during acceleration
  • Increased fuel consumption or poor fuel efficiency
  • Delayed throttle response
  • Engine hesitation when starting or accelerating

These symptoms can vary depending on the severity of the issue, but if you notice any of them, it’s time to get your vehicle checked.

How Serious is the P0106 Error Code?

Although the P0106 code is not as critical as some other engine trouble codes, it should still be taken seriously. When the MAP or barometric pressure sensor is not performing correctly, it can affect engine performance. This can lead to poor fuel efficiency, increased emissions, and general drivability issues, such as stalling or hesitation during acceleration.

If left unresolved, a malfunctioning MAP sensor or barometric pressure sensor can also cause damage to other engine components over time. So, while this error code may not immediately cause a breakdown, it’s important to address it as soon as possible to avoid more costly repairs later on.

How to Fix the P0106 Code?

Fixing the P0106 error code usually involves diagnosing the specific cause of the issue. Here’s a step-by-step guide to help you resolve the problem:

  • Step 1: Inspect the MAP or barometric pressure sensor – Start by checking the sensor for any visible signs of damage or wear. If it appears dirty or clogged, clean it thoroughly. If it’s damaged, replace it.
  • Step 2: Check for vacuum leaks – Inspect the vacuum hoses and connections to ensure there are no leaks. A vacuum leak can cause inaccurate pressure readings.
  • Step 3: Inspect wiring and connectors – Look for damaged or frayed wiring that could be disrupting the signal from the sensor to the ECU. Repair or replace any damaged wires or connectors.
  • Step 4: Test the sensor – Use a multimeter to test the voltage output from the sensor. Compare the readings with the manufacturer’s specifications to ensure the sensor is within the correct range. If it’s out of range, replace the sensor.
  • Step 5: Reset the error code – Once the issue has been addressed, reset the error code using an OBD-II scanner. If the problem is resolved, the code should not return.

If you're not comfortable performing these repairs yourself, it’s a good idea to take your vehicle to a qualified mechanic who can diagnose and fix the issue for you.

Conclusion

Addressing the P0106 code early can prevent further damage and restore your vehicle’s performance. If you're unsure about how to diagnose or fix the issue, seeking help from a professional mechanic is always a good option.
