P0106 Mazda Code - Manifold Absolute Pressure Sensor Signal Out of Range
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0106 Mazda Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM determines the MAP Sensor is stuck within the normal operating range. It accomplishes this by running 3 different models within the software to determine the values.
What are the Possible Causes of the DTC P0106 Mazda?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P0106 Mazda Code
1. What does the OBDII code P0106 mean for a Mazda?
Code P0106 indicates that the Manifold Absolute Pressure (MAP) sensor signal is out of range, meaning the sensor is providing erratic or implausible readings to the engine control module (ECM).
2. What are the common symptoms of a P0106 code in a Mazda?
Symptoms may include poor engine performance, rough idling, reduced fuel efficiency, stalling, difficulty starting, and the check engine light being illuminated.
3. What causes the P0106 code in a Mazda?
Common causes include a faulty MAP sensor, vacuum leaks, clogged air intake, damaged wiring or connectors, or a malfunctioning ECM.
4. Can a dirty air filter trigger a P0106 code in a Mazda?
Yes, a clogged or dirty air filter can restrict airflow and cause abnormal readings from the MAP sensor, potentially triggering a P0106 code.
5. How do I diagnose a P0106 code on my Mazda?
Start by inspecting the MAP sensor and its wiring, check for vacuum leaks, test the sensor’s voltage with a multimeter, and inspect the air intake system for blockages.
6. Is it safe to drive my Mazda with a P0106 code?
Driving with a P0106 code is not recommended, as it can lead to poor performance, increased emissions, and potential engine damage if the issue is not addressed.
7. How much does it cost to fix a P0106 code on a Mazda?
Repair costs vary but typically range from $100 to $300, depending on whether the MAP sensor needs replacement or if additional repairs like fixing vacuum leaks are required.
8. Can I fix the P0106 code on my Mazda myself?
If you’re comfortable with basic tools, you can inspect and replace the MAP sensor or check for vacuum leaks. However, more complex issues may require professional assistance.
9. What tools do I need to troubleshoot a P0106 code on my Mazda?
You’ll need an OBDII scanner, a multimeter to test the MAP sensor, and basic tools like screwdrivers and pliers for inspecting the intake system.
10. Will clearing the code solve the P0106 issue in my Mazda?
Clearing the code will temporarily turn off the check engine light, but unless the underlying issue is fixed, the code will likely return.
