P2293 on Hyundai by model: symptoms, diagnosis and fix
The GDI high-pressure fuel pump on 2.4L Tucson models can fail, causing extended crank times, rough idle, and stalling. The pump cam follower wears prematurely, reducing fuel rail pressure below specification. This is especially common above 80,000 miles.
Common Symptoms
- Long crank before starting
- Rough idle especially when cold
- Engine stalling at stops
- P0087 low fuel rail pressure code
- Hesitation under acceleration
How to Fix
Diagnose by checking fuel rail pressure with a scan tool (should be 500-2,000 PSI depending on load). Replace the high-pressure fuel pump (Hyundai part 35320-2G740). Also inspect and replace the cam follower/roller. Parts cost $250-400, labor $200-400. Total $450-800.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.

Reading and clearing the code is DIY work. Module replacement or reprogramming is not — most modules are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.

Frequently asked questions
What does P2293 mean on a Hyundai?
P2293 stands for "Fuel Pressure Regulator 2 Performance." This code means the engine computer has detected that the fuel pressure regulator 2 isn't performing as expected, so the system can't maintain the correct fuel pressure under varying conditions. On many direct-injection and high-pressure systems, regulator 2 controls the high-side fuel pressure, and the computer compares commanded pressure to what the fuel pressure sensor actually reports. When the measured pressure drifts too far from the target, it sets this performance code, which can cause hard starting, rough running, hesitation, reduced power, or stalling. Causes typically include a faulty regulator or high-pressure pump, a fuel delivery restriction, or a pressure sensor problem. On Hyundai it is documented across 1 model: Tucson.
What are the most common causes of P2293?
The most common causes of P2293 are: Faulty fuel pressure regulator (regulator 2), Failing high-pressure fuel pump, Faulty or out-of-range fuel rail pressure sensor, Clogged fuel filter or restricted fuel supply, Weak low-pressure (lift) pump feeding the high-pressure system, Leaking fuel injector bleeding off pressure, Wiring or connector fault to the regulator/pump, Air or contamination in the fuel system. The specific cause varies by vehicle.
How much does it cost to fix P2293 on a Hyundai?
Published repair estimates on Hyundai range from $450 to $800 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
