P2227 ACURA – Barometric Pressure Sensor Range/Performance Problem

P2227 ACURA Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light),Engine rough idle,Engine hesitation

P2227 ACURA Possible Causes

Powertrain Control Module (PCM) outdated or incorrect software,Faulty Powertrain Control Module (PCM)

P2227 ACURA 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 ??ide-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.
