P0120 on Your All-New 2024 Lincoln Nautilus
The 2024 Nautilus is a completely redesigned vehicle — and seeing P0120 on a brand-new platform is concerning. This code signals a throttle position sensor circuit malfunction. The 2024 Nautilus features a new 2.0L turbocharged four-cylinder paired with an electric motor in some trims, on a thoroughly updated architecture. The electronic throttle body integrates the TPS, and when the ECU detects abnormal circuit signals, it enters a protective power-limited mode.
What You'll Notice
- Check engine light and/or powertrain warning
- Engine power severely limited
- Throttle pedal may feel unresponsive
- Possible idle instability
- Driver-assist features may deactivate
Probable Causes
1. First-Year Production Throttle Body Issue
As a completely redesigned 2024 model, first-year production vehicles occasionally have component quality variations. A throttle body that left the factory out of specification is the top suspect.
2. New Platform Software Calibration
First-year models on new platforms frequently receive post-launch software updates. A PCM calibration addressing throttle body adaptation is likely available or forthcoming from Ford/Lincoln.
3. Assembly Connector or Wiring
New production line processes can result in improperly routed wiring or incompletely seated connectors that manifest after initial driving.
4. Communication Protocol Issue
New electrical architectures can have CAN bus timing or protocol issues between the throttle body controller and PCM that generate P0120.
5. Pedal Assembly Defect
The redesigned pedal assembly may have early-production quality variations in the dual position sensors.
Diagnostic Steps
- Lincoln dealer scans with latest FDRS software for 2024 Nautilus
- Check for TSBs specific to the redesigned 2024 platform
- Verify all software modules are at latest calibration level
- Inspect throttle body connector and harness routing
- Monitor live TPS and APP data for signal integrity
Repair Costs
- All repairs under warranty: $0
- Throttle body replacement (out of pocket): $350–$750
Can I Drive With P0120?
Not safely in traffic. Use Lincoln's complimentary roadside assistance to tow the Nautilus to the dealer. Power-limited mode is not suitable for normal driving.
DIY vs Professional
Dealer only. Your 2024 Nautilus is under full factory warranty — 4-year/50,000-mile comprehensive and 6-year/70,000-mile powertrain. All throttle system repairs are covered at no cost.
Frequently Asked Questions
Is this a first-year problem with the redesigned Nautilus?
First-year models on new platforms can experience teething issues. This is exactly why the factory warranty exists. The dealer will resolve it at no cost.
Will Lincoln extend my warranty if this is a design issue?
If Ford/Lincoln identifies a pattern, they may issue a warranty extension or recall. Your standard warranty covers this regardless.
Is the 2024 Nautilus reliable overall?
One P0120 code does not indicate systemic reliability issues. Electronic components occasionally fail — the warranty handles these situations. Judge reliability after long-term ownership data is available.
Can I get a refund or exchange?
If the vehicle experiences repeated unfixable issues, lemon law protections may apply. However, P0120 is typically a straightforward repair. Document all dealer visits and repair attempts.
