5. Key Functions & Benefits (Solve User Pain Points)
A failed NOx sensor will trigger engine derate, poor fuel economy, and emission test failure. Our LC3A-5L248-AC replacement sensor completely fixes these common problems:
- Eliminate Fault Codes: Permanently clears P20EE, P2200, P2201, P2202, P2209, P2463 and other NOx & SCR system error codes.
- Restore Full Engine Power: Fixes truck reduced power mode, torque limitation, and slow acceleration caused by sensor failure.
- Optimize SCR System Operation: Accurately monitors exhaust NOx concentration to adjust urea injection volume, reducing abnormal urea consumption and extending SCR & DPF service life.
- Pass Emission Inspection: Meets EPA emission standards, effectively solves excessive NOx exhaust emissions and vehicle inspection failure issues.
- Plug & Play Installation: Fully consistent with OEM size and interface, no extra programming or modification required after installation, saving time and maintenance costs.
- Durable & Stable: High-temperature and corrosion-resistant materials adapt to harsh exhaust working environments, avoiding frequent sensor failure.
6. Common Failure Symptoms (When You Need Replacement)
If your Ford 6.7L Super Duty truck has the following symptoms, your original NOx sensor is damaged and needs immediate replacement:
- Check engine light (MIL) stays on continuously
- Vehicle enters power derate mode with weak acceleration
- Abnormally high or unstable urea fluid consumption
- Failed vehicle exhaust emission test
- SCR system prompt and exhaust system alarm
- Engine idle jitter and poor fuel economy
7. Frequently Asked Questions (FAQ for SEO)
Q1: Is this LC3A-5L248-AC sensor compatible with 2022 Ford F350 6.7L diesel?
A: Yes. It is fully compatible with all 2017-2022 Ford F250/F350/F450/F550 Super Duty 6.7L V8 turbo diesel models, covering all year ranges in the fitment list.
Q2: What is the difference between upstream and downstream NOx sensors?
A: This LC3A-5L248-AC (904-6018) is a downstream NOx sensor. The upstream model is LC3A-5E145-BA (904-6030). The two sensors have different parameters and installation positions and cannot be interchanged.
Q3: Do I need professional programming after installation?
A: No programming or calibration needed. It is a direct OEM replacement part with plug-and-play design, perfectly matching the original vehicle system.
Q4: What fault codes can this NOx sensor fix?
A: It mainly solves NOx sensor circuit and signal failure codes including P20EE, P2200, P2201, P2202, P2209 and P2463.
