4 vehicles · 4 makes · $450-$1,800 repair
Most Reported On
P0089 is an OBD-II diagnostic trouble code meaning “Fuel Pressure Regulator 1 Performance.” This code means the engine computer detected that the fuel pressure regulator is not controlling fuel pressure correctly, so actual fuel pressure does not match what the computer commands. It monitors the regulator's ability to maintain proper pressure in the fuel system, usually on direct-injection or high-pressure systems. When pressure drifts too far from target, this code sets. It can cause hard starting, hesitation, reduced power, or stalling. This code is most commonly reported on 2015-2024 Audi S3, 2023-2024 Chevrolet Equinox (LS, LT, RS, Premier), and 2021 Kia Sorento (SX, SX Prestige, X-Line), plus 1 other vehicle, with repair costs ranging from $450 to $1,800.
