DTC P2228, P2229: General Description

Courtesy of HONDA, U.S.A., INC.

The barometric pressure (BARO) sensor is built into the powertrain control module (PCM), and it monitors atmospheric pressure. The BARO sensor output voltage is converted to A/D in the sensor inside, and transmitted to a CPU by serial communication. If the atmospheric pressure value sent from the BARO sensor is abnormal, the PCM detects a malfunction and stores a DTC.
