P0089: Fuel Pressure Regulator 1 Performance
5 vehicles · 4 makes · $300-$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, 2013-2019 Cadillac XTS, and 2012-2017 Hyundai Veloster (Turbo, Turbo R-Spec, base 1.6), plus 2 other vehicles, with repair costs ranging from $300 to $1,800.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
