P0120 on Your 2024 Genesis GV70
Your 2024 GV70 has flagged P0120 — a throttle position sensor circuit malfunction. The 2024 GV70 continues with the 2.5T four-cylinder (300 hp) or 3.5T twin-turbo V6 (375 hp), both using electronic throttle bodies with integrated TPS. Under Genesis's industry-leading warranty, this is a completely dealer-handled situation with complimentary concierge service.
Symptoms
- Check engine light on
- Power significantly reduced — limp mode
- Throttle unresponsive or laggy
- Sport and performance features disabled
- Idle instability
Leading Causes
1. Throttle Body Manufacturing Defect
On a low-mileage 2024 model, an internal defect in the electronic throttle body is the primary suspect.
2. ECU Software Calibration
Genesis may have released post-production powertrain calibration updates for the 2024 model year.
3. Assembly Connector Issue
Connector not fully seated during factory assembly, causing intermittent signal dropout with vibration.
4. Wiring Routing Problem
Harness pinched during assembly, developing insulation damage over initial driving.
5. Pedal Sensor Defect
Factory-defective accelerator pedal position sensor producing abnormal signals.
Diagnostic Steps
- Genesis dealer GDS scan for full diagnostics
- Check for TSBs and software updates
- Inspect connector seating and wiring
- Monitor live TPS and APP data
- Review freeze frame data
Repair Costs
