P2226 Barometric Pressure Circuit
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.
DTC Description
If the change of the barometric pressure is out of specified range, ECM sets P2226.
