DTC P2226 Barometric Pressure Circuit
DTC P2227 Barometric Pressure Circuit Range / Performance
DTC P2228 Barometric Pressure Circuit Low Input
DTC P2229 Barometric Pressure Circuit High Input
To detect atmospheric pressure, the built-in atmospheric pressure sensor in the ECM is used for the common rail system. Following the changes in the atmospheric pressure, the ECM corrects the fuel injection volume, timing and duration, and adjusts the common rail internal fuel pressure in order to optimize engine combustion.
