Code P2227 2009 Honda Accord Description

The Barometric pressure (BARO) sensor is built into the Powertrain Control Module (PCM) and monitors atmospheric pressure. When the throttle valve is wide open, the Manifold Absolute Pressure (MAP) sensor output is nearly equal to the BARO sensor output. If the throttle position is beyond a value stored in the PCM that is used to detect wide-open throttle, and if the difference between the MAP sensor output and the BARO sensor output is equal to or greater than a set value, a malfunction in the BARO sensor output is detected and a Diagnostic Trouble Code (DTC) is stored.
