P2229 Barometric Pressure Circuit High Input - General Information

Component Location





General Description

ECM has a barometric pressure sensor built-in its inner structure, where it detects the atmospheric pressure at the vehicle's current location. The barometric pressure sensor calculates the density of air(quantity of oxygen) and accurately detects the intake air amount along with intake air sensor and intake air temperature sensor. This does an important role in compensating the amount of fuel when driving in hillsides areas where difference in air density(oxygen) exists, and also in EGR control.

DTC Description

ECM sets DTC P2229 if the ECM detects that barometric pressure sensor circuit is short to battery.
