Q: What does code P2A0D mean?

Manifold Absolute Pressure Sensor B Circuit High. P2A0D indicates that the powertrain control module has detected an abnormally high voltage signal on the circuit for Manifold Absolute Pressure Sensor B, which is a secondary MAP sensor used on some engines to monitor intake pressure. The computer sees a signal voltage that exceeds the expected range for the current operating conditions, which usually points to a short to voltage, an open ground, or a faulty sensor.
