P0120 Detected on Your 2024 Genesis GV80
Your 2024 GV80 has flagged P0120 — a throttle position sensor circuit malfunction. The refreshed 2024 GV80 offers the 2.5T four-cylinder (300 hp) or the upgraded 3.5T twin-turbo V6 (375 hp), both with electronic throttle bodies integrating the TPS. Under Genesis's comprehensive warranty with concierge service, this is handled with minimal inconvenience to you.
Symptoms
- Check engine light on
- Power reduced — limp mode

Probable Causes
1. Throttle Body Defect
Manufacturing defect in the electronic throttle body on a low-mileage vehicle — the primary suspect.
2. Software Update Needed
Post-production ECU calibration for the refreshed 2024 powertrain may address throttle adaptation parameters.
3. Connector or Wiring
Assembly-related connector or harness issue manifesting after initial driving.
4. Turbo System Interaction
Boost control and throttle body communication issue, especially on the 3.5T.
5. Pedal Sensor
Factory-defective accelerator pedal position sensor.

Frequently Asked Questions
Is my 2024 GV80 fully covered?
Yes. Genesis's 5-year/60,000-mile basic warranty covers all throttle components. The 10-year powertrain warranty adds further protection.
Will Genesis pick up my GV80?
Yes. Genesis Concierge provides complimentary vehicle pickup and loaner delivery for warranty repairs — part of the ownership experience.
Is the refreshed 2024 GV80 different mechanically?
The 2024 GV80 received a refresh with interior and technology updates. The powertrain options remain the same 2.5T and 3.5T engines with the same throttle body configurations.
Does this affect the GV80's safety rating?
A single throttle fault does not affect the vehicle's crash safety rating. The limp mode that activates is a safety feature working as designed to protect occupants.
