Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle.

Can a bad manifold pressure sensor cause p0101?

I did some research about P0101, and bad manifold absolute pressure (MAP) sensor will cause P0101. How can I read the value of MAP sensor data using torque app. When I displayed “intake manifold pressure”, the torque app always shows zero values.

Why does my car have a p0106 error code?

If the P0106 error code has appeared, it is because the PCM detected a pressure discrepancy in the manifold. Your car will fall into one of three categories: This will determine which sensor detected the issue, but the same P0106 error code will be displayed no matter which type of sensor you have.
