What does code P227E mean?

Q: What does code P227E mean?

Barometric Pressure Sensor C Circuit Intermittent/Erratic. P227E indicates that the powertrain control module (PCM) has detected an intermittent or erratic signal from the barometric pressure (BARO) sensor C circuit. The PCM monitors the BARO sensor voltage and flags this code when the signal jumps unpredictably or drops out momentarily, rather than reading a steady pressure value.
