WJIECO 68167883AA NOx Sensor is an OE-grade upstream pre-SCR position 1 NOx Sensor engineered for Ram ProMaster 1500/2500/3500 3.0L I4 EcoDiesel turbo diesel 2014–2016. Mounted before the SCR catalyst on exhaust pipe, it measures raw engine-out NOx levels and feeds accurate exhaust data to the ECM for precise DEF dosing control and emissions compliance. Direct replacement for OE# 68167883AA, 0281006642, 68167883AB. 12V, plug-and-play installation, no programming required. Backed by 12-month WJIECO manufacturer warranty.

68167883AA NOx Sensor Overview

The 68167883AA NOx Sensor manufactured by WJIECO is the upstream pre-SCR NOx sensor for Ram ProMaster cargo vans equipped with 3.0L I4 EcoDiesel from 2014 to 2016. This pre-catalyst NOx sensor reads engine-out NOx before the SCR unit, allowing the ECM to calculate the correct DEF injection rate and keep exhaust 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 ProMaster commercial van owners run into intermittent faults during delivery routes, highway cruising and loaded work conditions; these are typical symptoms of a degraded NOx sensing element. This sensor cross-references interchange numbers: 68167883AA, 0281006642, 68167883AB for fast lookup by repair shops and diesel technicians across the USA.

H2: OEM-Grade Construction & Strict Factory Testing

Our 68167883AA 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 daily commercial delivery 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 68167883AA 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.

H2: Vehicle Fitment

Compatible Engine: 3.0L I4 EcoDiesel Turbo Diesel (2014–2016)

• Ram ProMaster 1500 (2014–2016) 3.0 EcoDiesel
• Ram ProMaster 2500 (2014–2016) 3.0 EcoDiesel
• Ram ProMaster 3500 (2014–2016) 3.0 EcoDiesel

Important note: This is the 12V UPSTREAM PRE-SCR POSITION 1 NOx Sensor. NOT compatible with downstream post-SCR NOx sensor 68146138AD, NOT compatible with Jeep Grand Cherokee EcoDiesel, NOT compatible with Ram heavy-duty 6.7 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 68167883AA NOx Sensor

Replacing your faulty upstream pre-SCR NOx Sensor with the WJIECO 68167883AA 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 Ram ProMaster fleet owners and delivery operators, proactive replacement prevents unexpected derate and costly roadside 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 commercial van fleets and professional diesel repair facilities.

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

This 68167883AA NOx Sensor is a true direct-fit replacement for the factory upstream pre-SCR NOx Sensor on 2014–2016 Ram ProMaster 1500/2500/3500 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 68167883AA NOx Sensor is fully bench tested before shipment. If you need a reliable 12V upstream NOx Sensor compatible with 68167883AA 0281006642 for Ram ProMaster 3.0 EcoDiesel, this WJIECO NOx Sensor will return your SCR emissions system to normal operation.
