Q: What does code P2B7A mean?

EVAP System Pressure Sensor/Switch C Circuit. P2B7A indicates that the powertrain control module has detected an electrical fault in the circuit for EVAP system pressure sensor or switch C, which is one of the sensors used to monitor fuel vapor pressure in the evaporative emissions system. The computer compares the signal voltage on this circuit to expected values and sets the code when the voltage stays outside the valid range for too long.
