Q: What does code P2A46 mean?

Alternative Fuel Tank C Pressure Sensor Circuit. P2A46 indicates that the powertrain control module has detected an abnormal signal from the pressure sensor mounted on the alternative fuel tank designated as Tank C. The computer compares the sensor's voltage output against expected values for the current operating conditions and sets this code when the signal falls outside the valid range or is inconsistent with other pressure readings.
