Manifold absolute pressure sensor (IDA) detects changes in intake manifold pressure resulting from changes in engine load and changes in vehicle speed.
The MAP sensor also measures barometric pressure. This state is achieved in part by the calculations of the manifold absolute pressure sensor (IDA). With the ignition on and engine off, the ECM considers manifold pressure equal to atmospheric pressure and adjusts the air/fuel ratio accordingly.
This compensation of the height of the vehicle above sea level allows you to maintain the characteristics of the car and keep the amount of harmful emissions at a low level. The barometric pressure function is periodically implemented under stable driving conditions or wide open damper. In the event of a MAP sensor barometric system failure, the ECM will revert to default barometric pressure. In the event of a malfunction in the MAP sensor circuit, DTC P0107 or P0108 will be assigned.
