Q: What does code P2A0F mean?

Fuel Supply Heater Performance. P2A0F indicates that the powertrain control module has detected a performance fault in the fuel supply heater circuit, which is used on some diesel and flex-fuel vehicles to warm the fuel and prevent gelling or improve cold-start vaporization. The computer monitors the heater's electrical current or temperature response and sets this code when the heater does not heat, heats too slowly, or draws current outside the expected range.
