DTC Advanced Diagnostics: P2228, P2229: Notes

DTC P2228:  Barometric Pressure (BARO) Sensor Circuit Low Voltage DTC P2229:  Barometric Pressure (BARO) Sensor Circuit High Voltage

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 measurement value of the BARO sensor is abnormal for a specified time, the PCM detects a malfunction and stores a DTC.
