WJIECO LC3A-5L248-AC NOx Sensor Long-lasting. Cross references 904-6018, HC3A-5L248-CB, HC3Z-5L248-A. 12V upstream NOx Sensor for Ford 6.7L Power Stroke V8 Diesel 2017–2022 Super Duty. Fits F250, F350, F450, F550, plug & play install.

LC3A-5L248-AC NOx Sensor Overview

The LC3A-5L248-AC NOx Sensor manufactured by WJIECO is the upstream NOx sensor installed before the DPF/SCR assembly for 2017–2022 Ford F250, F350, F450, F550 Super Duty equipped with the 6.7L Powerstroke diesel engine. This inlet NOx sensor reads raw engine-out NOx levels, allowing the PCM to calculate precise DEF injection rates and maintain SCR emissions compliance.

A failed upstream NOx sensor commonly triggers fault codes such as P20EE, P2200, P2209, illuminates the check engine light, and activates reduced power derate. Many truck owners and diesel technicians see intermittent faults that appear under loaded towing conditions, which are typical signs of a degraded NOx sensing element. This sensor cross-references interchange numbers: LC3A-5L248-AC, 904-6018, HC3A-5L248-CB, HC3Z-5L248-A, A2C1069790001 for fast lookup by fleet shops and independent repair garages across the USA.

H2: OEM-Grade Construction & Strict Factory Testing

Our LC3A-5L248-AC NOx Sensor adopts a high-stability ceramic sensing chip, heavy-duty heat-resistant stainless steel probe housing and fully sealed wiring assembly with OEM matching connector. It is built to withstand sustained exhaust heat, constant engine vibration, rapid thermal cycling, heavy soot buildup, plus road salt, mud and moisture exposure during towing and highway use. Low-cost generic NOx sensors commonly skip long-duration high-temperature burn-in calibration, which leads to unstable readings and premature failure after short service time.

Every finished LC3A-5L248-AC NOx Sensor passes a full series of factory quality validation steps: precision NOx signal calibration, high-temperature aging cycle test, waterproof seal pressure test and connector pin continuity inspection before packing. This strict QC process guarantees stable NOx readings, reliable CAN communication with the PCM and extended service life inside the harsh diesel exhaust aftertreatment environment.

Compatible Engine: Ford 6.7L Power Stroke V8 Diesel (2017–2022)

• Ford F-250 Super Duty
• Ford F-350 Super Duty
• Ford F-450 Super Duty
• Ford F-550 Super Duty

Important note: This is the 12V UPSTREAM NOx Sensor, Dorman 904-6018. NOT compatible with 2011–2016 Ford 6.7L Powerstroke, NOT compatible with Ram, Cummins ISB / ISX heavy-duty trucks. Verify your VIN, engine, connector shape and original OEM part number before placing your order. Installing the wrong NOx Sensor will result in persistent SCR faults and derate that cannot be cleared easily.

H2: Core Benefits of LC3A-5L248-AC NOx Sensor

Replacing your faulty upstream NOx Sensor with the WJIECO LC3A-5L248-AC NOx Sensor restores accurate engine-out NOx measurement for the SCR DEF dosing system. Reliable upstream NOx readings allow the PCM to maintain proper DEF injection rates, clear NOx and SCR related diagnostic trouble codes, remove engine power derate restrictions, and complete emissions readiness monitors required for state inspection. For towing fleets and work trucks, proactive replacement prevents unexpected roadside derate and costly job downtime.

Robust, factory-calibrated construction greatly reduces early failure and intermittent fault codes that plague low-cost alternatives. This aftermarket NOx Sensor delivers OEM-matching performance at a much lower price than dealership replacement parts, making it a reliable choice for US Super Duty owners, towing fleets and professional diesel repair facilities.

H2: Plug-and-Play Installation, No Dealer Programming Required

This LC3A-5L248-AC NOx Sensor is a true direct-fit replacement for the factory upstream NOx Sensor on Ford 6.7L Powerstroke 2017–2022. Thread size, probe length, mounting thread, connector profile and wiring pinout all match OEM specifications exactly. Remove the old faulty sensor, torque the new sensor to factory torque specs and reconnect the stock wiring harness. There is no wire cutting, harness modification or ECU flash programming needed. After installation, clear all associated diagnostic trouble codes with a diesel scan tool and perform a loaded test drive. A full drive cycle is recommended so the PCM can run its SCR self-test and reset emissions readiness status.

Every WJIECO LC3A-5L248-AC NOx Sensor is fully bench tested before shipment. If you need a reliable 12V upstream NOx Sensor compatible with LC3A-5L248-AC and 904-6018 for Ford 6.7L Powerstroke F250/F350/F450/F550 Super Duty, this WJIECO NOx Sensor will return your SCR emissions system to normal operation.
