P0106 – Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance
Introduction
Let’s break down exactly what the P0106 trouble code means for your Exeed and how to fix it.
The P0106 error is **most likely caused by a faulty manifold absolute pressure (MAP) sensor or barometric pressure (BARO) sensor**. This code is considered to be of **medium severity level**, and the **urgency of repair is soon**, as it can lead to decreased engine performance and fuel efficiency.
WHAT DOES CODE P0106 MEAN
The P0106 trouble code is related to the Manifold Absolute Pressure/Barometric Pressure Circuit, which is a critical component of the engine management system. This system is responsible for monitoring the pressure inside the intake manifold and adjusting the engine’s performance accordingly. The P0106 code indicates that the MAP or BARO sensor is not functioning within the specified range, which can affect the engine’s performance, fuel efficiency, and overall drivability.
COMMON Exeed MODELS AFFECTED
The P0106 error can occur on various Exeed models, including:
- Exeed TXL
- Exeed LX
- Exeed TX
- Exeed VX
- Exeed RX

| Clogged or dirty air filter | Medium |
REAL-WORLD DRIVING SCENARIOS
When driving with the P0106 trouble code, the driver may experience decreased engine performance, particularly during acceleration or when driving uphill. The engine may also stall or hesitate, and the Check Engine Light (CEL) may be illuminated. In some cases, the engine may run rough or lose power when accelerating.
DIAGNOSTIC STEPS
To diagnose the P0106 trouble code, the following steps can be taken:
IF the MAP or BARO sensor is suspected to be faulty, THEN inspect the sensor and its wiring for any signs of damage or corrosion. IF the sensor is found to be faulty, THEN replace it with a new one. IF the sensor is not faulty, THEN check the intake manifold for any vacuum leaks or blockages. IF a leak or blockage is found, THEN repair or replace the intake manifold as necessary.
COMMON DIAGNOSTIC MISTAKES
When diagnosing the P0106 trouble code, the following mistakes can be made:
- Replacing the MAP or BARO sensor without checking the wiring or intake manifold for any issues
- Not checking the ECU software for any updates or issues
- Not inspecting the air filter for any blockages or damage
- Not checking the fuel system for any issues or leaks
- Not using a scan tool to monitor the engine’s performance and troubleshoot the issue
WHEN NOT TO REPLACE THE SENSOR
The MAP or BARO sensor should not be replaced if the issue is caused by a wiring or connector problem, an intake manifold vacuum leak, or an ECU software issue. In these cases, replacing the sensor will not solve the problem and may lead to further issues.
HOW TO FIX
To fix the P0106 trouble code, the following steps can be taken:
- Replace the faulty MAP or BARO sensor with a new one
- Repair or replace the intake manifold if a vacuum leak or blockage is found
- Check and update the ECU software if necessary
- Inspect and clean or replace the air filter if necessary
- Check the fuel system for any issues or leaks
SEVERITY LEVEL
The P0106 trouble code is considered to be of medium severity level, as it can lead to decreased engine performance and fuel efficiency. The driving risk is medium, and the urgency of repair is soon. The engine impact explanation is that the P0106 code can cause the engine to run rich or lean, leading to decreased performance and fuel efficiency.
IS IT SAFE TO DRIVE WITH THIS CODE
It is not recommended to drive with the P0106 trouble code for an extended period, as it can lead to decreased engine performance and fuel efficiency. However, if the code is not causing any significant issues, it may be safe to drive the vehicle for a short period. The risks and driving limitations include decreased engine performance, reduced fuel efficiency, and potential engine damage.
ESTIMATED REPAIR COST
The estimated repair cost for the P0106 trouble code can range from $200 to $1,000, depending on the cause of the issue and the necessary repairs.
PREVENTIVE MAINTENANCE TIPS
To prevent the P0106 trouble code from occurring, the following maintenance tips can be followed:
- Regularly inspect the air filter and replace it as necessary
- Check the intake manifold for any vacuum leaks or blockages
- Monitor the engine’s performance and troubleshoot any issues promptly
- Keep the ECU software up to date
- Check the fuel system for any issues or leaks
EXPERT MECHANIC NOTE (E-E-A-T)
When diagnosing the P0106 trouble code, it is essential to use a scan tool to monitor the engine’s performance and troubleshoot the issue. Additionally, inspecting the air filter and intake manifold for any blockages or leaks can help identify the cause of the issue. Replacing the MAP or BARO sensor may not always solve the problem, and further diagnostics may be necessary to identify the root cause of the issue.
TOOLS REQUIRED FOR DIAGNOSTICS
The following tools are required for diagnosing the P0106 trouble code:
- Scan tool
- Multimeter
- Wiring diagram
- Intake manifold vacuum gauge
- Air filter inspection tool
TECHNICAL REFERENCE VALUES
The following technical reference values can be used to diagnose the P0106 trouble code:
| Parameter | Normal Range | Fault Indication Behavior |
|---|---|---|
| MAP sensor voltage | 0.5-4.5V | Below 0.5V or above 4.5V |
| BARO sensor voltage | 0.5-4.5V | Below 0.5V or above 4.5V |
| Intake manifold vacuum | 15-20 inHg | Below 15 inHg or above 20 inHg |
