Alternative Fuel Tank C Pressure Sensor Range/Performance. P2A47 indicates that the powertrain control module has detected an out-of-range or erratic signal from the pressure sensor mounted on the alternative fuel tank designated as Tank C. The computer compares the sensor voltage against expected values for the current operating conditions and flags the circuit when the signal falls outside a calibrated window or fails a rationality check.
