Q: What does code P2A0A mean?

Manifold Absolute Pressure Sensor B Circuit. P2A0A indicates that the engine control module has detected a fault in the electrical circuit for Manifold Absolute Pressure Sensor B, which is a secondary MAP sensor used on some engines to monitor intake pressure. The computer compares the sensor's signal voltage against expected values and sets this code when the circuit is out of range, intermittent, or implausible.
