What is a Baro sensor?

A barometric pressure sensor is a sensor that detects atmospheric pressure. Various types of pressure sensors exist utilizing different materials and methods as shown below based on the pressure values to be measured. Among these, sensors that detect atmospheric pressure are called barometric pressure sensors.

What does P0106 code mean?

Code P0106 is triggered when your PCM sees that the voltage pertaining to the manifold pressure is moving up and down in an erratic way, and also doesn’t see any corresponding change in engine load.

What can a faulty MAP sensor cause?

MAP sensor problems could trigger a DTC and check engine light. MAP sensors fail by getting clogged, contaminated, or damaged. If the MAP sensor goes bad, the ECM can’t accurately calculate engine load, which means the air-fuel ratio will become either too rich (more fuel) or too lean (less fuel).
