Q: What does code P2A8C mean?

Alternative Fuel Vaporizer B Performance. P2A8C indicates that the powertrain control module (PCM) has detected a performance fault in the alternative fuel vaporizer, which is the component that turns liquefied alternative fuel into a combustible vapor before it reaches the engine. The PCM monitors the vaporizer's ability to reach and maintain the expected temperature or vapor output within a calibrated time, and it sets this code when the measured performance falls outside the acceptable range.
