P2226 Honda Code - Barometric Pressure Sensor Circuit Malfunction

Quick Answer

The Barometric pressure (BARO) sensor is built into the Powertrain Control Module (PCM) and monitors atmospheric pressure. Common causes include Powertrain Control Module (PCM) outdated or incorrect software, Faulty Powertrain Control Module (PCM). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2226 Honda 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.
