Enter the error code and car brand

Vehicle engine and/or automatic transmission

Code: P0106 - The intake manifold air pressure sensors (G71 and F96) are sending an invalid signal, meaning the engine control unit can’t read air pressure correctly.

The OBD error P0106 on Volkswagen is related to an incorrect signal from the manifold absolute pressure (MAP) sensor, which measures the air pressure in the intake manifold. This information is critical for calculating fuel delivery and ignition timing. Therefore, a failure in this system can lead to unstable engine performance.

Causes and Symptoms of DTC P0106 on VW

On Volkswagen models such as Passat B6, Golf 5, Jetta, Tiguan, and Polo, the DTC P0106 error may be caused by the following factors:

Contamination or failure of the MAP sensor (sensor G71)
Damage to the sensor connectors or wiring
Air intake leaks in the intake manifold
Issues with the engine control unit (ECU)

When this error occurs, drivers may notice unstable engine idle, loss of power, increased fuel consumption, and difficulty starting. In some cases, the vehicle may enter limp mode, limiting engine RPM.

Methods to Fix OBD P0106 Error on Volkswagen

To diagnose the P0106 error on a Volkswagen, first, check the condition of the MAP sensor - its contacts, connections, and level of contamination. If the sensor is dirty, clean or replace it. Then, inspect the intake system for leaks, as air intake can distort sensor readings. Also, check the wiring and connectors for damage. If all components are in good condition but the error persists, perform testing and, if necessary, reprogram the control unit.

Conclusions

Failure to address the issue in time can lead to reduced vehicle performance and increased engine wear. It is recommended not to delay diagnostics, especially if the symptoms are pronounced.
