1 vehicles · 1 makes · $30-$4,000 repair
Most Reported On
P2294 is an OBD-II diagnostic trouble code meaning “Fuel Pressure Regulator 2 Control Circuit.” This fuel system code means the control circuit for the second fuel pressure regulator is faulty. On direct-injection or some diesel/high-pressure fuel systems, a pressure regulator (control valve) adjusts fuel rail pressure to match engine demand; regulator 2 is the second such valve. The computer commands the regulator and monitors its electrical circuit, setting this code when it sees an open, short, or out-of-range condition. Depending on the system, you may experience hard starting, rough running, reduced power, stalling, or fuel-economy problems. This code is most commonly reported on 2009-2015 Audi TTS (TTS), with repair costs ranging from $30 to $4,000.
