WJIECO 68146136AD NOx Sensor. Cross references Bosch 0281006643, 68146136AB. 12V upstream pre-SCR NOx Sensor for Jeep Grand Cherokee WK2 3.0L EcoDiesel 2014–2019. Plug & play direct replacement.

68146136AD NOx Sensor Overview

The 68146136AD NOx Sensor manufactured by WJIECO is the upstream pre-SCR NOx sensor for Jeep Grand Cherokee WK2 equipped with 3.0L EcoDiesel EXF/EXN diesel from 2014 to 2019. This pre-cat NOx sensor reads engine-out NOx before the SCR, allowing the ECM to calculate correct DEF injection volume and keep emissions within EPA standards.

A faulty upstream NOx sensor commonly triggers DEF dosing codes, check engine light and engine derate. Common related DTCs include P20EE, P2200, P2209. Many EcoDiesel owners experience intermittent faults under highway cruising and towing loads, which are typical signs of degraded NOx sensing element. This sensor cross-references interchange numbers: 68146136AD, 0281006643, 68146136AB, 68146136AC for fast lookup by repair shops and diesel technicians across the USA.

H2: OEM-Grade Construction & Strict Factory Testing

Our 68146136AD 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, engine vibration, rapid thermal cycling, soot buildup, plus road salt, mud and moisture during highway driving and towing. 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 68146136AD 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 ECM and extended service life inside the harsh diesel exhaust aftertreatment environment.

Compatible Engine: 3.0L V6 EcoDiesel EXF / EXN Turbo Diesel (2014–2019)

• Jeep Grand Cherokee WK2 (2014–2019) 3.0 EcoDiesel

Important note: This is the 12V UPSTREAM PRE-SCR POSITION 1 NOx Sensor. NOT compatible with downstream post-SCR NOx sensor, NOT compatible with gasoline models, NOT compatible with Ram heavy-duty Cummins 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 68146136AD NOx Sensor

Replacing your faulty upstream pre-SCR NOx Sensor with the WJIECO 68146136AD NOx Sensor restores accurate engine-out NOx measurement for the DEF dosing system. Reliable upstream NOx readings allow the ECM 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 Jeep EcoDiesel owners who tow and travel long distances, proactive replacement prevents unexpected derate and roadside breakdowns.

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 EcoDiesel SUV owners and professional diesel repair facilities.

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

This 68146136AD NOx Sensor is a true direct-fit replacement for the factory upstream pre-SCR NOx Sensor on 2014–2019 Jeep Grand Cherokee WK2 3.0 EcoDiesel. 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 ECM 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 ECM can run its SCR self-test and reset emissions readiness status.

Every WJIECO 68146136AD NOx Sensor is fully bench tested before shipment. If you need a reliable 12V upstream NOx Sensor compatible with 68146136AD 0281006643 for Jeep Grand Cherokee EcoDiesel, this WJIECO NOx Sensor will return your SCR emissions system to normal operation.
