Our automotive experts have put together the following information about the P2227 diagnostic trouble code. We've provided the common symptoms that occur when this code is set along with the frequent repairs that address the issues related to the P2227 code.

 

What Does P2227 Code Mean?

OBD-II Code P2227 is defined as a Barometric Pressure Sensor "A" Circuit Range/Performance

The Barometric Pressure Sensor monitors ambient air pressure. Most manufacturers have this sensor integrated into the Mass Airflow Sensor (MAF) or the Powertrain Control Module (PCM). The PCM compares this reading to other sensors to verify the Barometric Pressure Sensor's Calibration. If the PCM determines that the sensor has lost its calibration or voltage reading from the sensor is incorrect, the PCM will set code P2227.

 

P2227 Symptoms

  • Decreased engine performance
  • Increased fuel consumption

Common Problems That Trigger the P2227 Code

  • Clogged air filter
  • Mass Air Flow (MAF) sensor failure
  • Powertrain Control Module (PCM) failure
  • Powertrain Control Module (PCM) software needs to be updated
  • Wiring issue
