19302360 NOx Sensor Overview

The 19302360 NOx Sensor manufactured by WJIECO is the post-SCR downstream rear NOx sensor for GM 6.6L LML Duramax diesel trucks and vans from 2010 to 2015. This outlet NOx sensor measures residual NOx after the SCR, allowing the ECM to confirm SCR efficiency and prevent DEF dosing errors and ammonia slip.

A faulty downstream NOx sensor commonly triggers SCR efficiency codes, check engine light and engine derate. Common related DTCs include P20EE, P2201, P229F. Many Duramax owners experience intermittent faults under highway cruising and heavy towing loads, which are typical signs of degraded NOx sensing element. This sensor cross-references interchange numbers: 19302360, 5WK96645, 19301329, 12662972, 5WK96645F, 5WK96645H, NOX003 for fast lookup by repair shops and diesel technicians across the USA.

H2: OEM-Grade Construction & Strict Factory Testing

Our 19302360 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 towing and highway driving. 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 19302360 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.

Important note: This is the 12V DOWNSTREAM REAR OUTLET NOx Sensor, Continental 5WK96645. NOT compatible with 2017+ L5P Duramax, NOT compatible with Ford Powerstroke, Ram 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 19302360 NOx Sensor

Replacing your faulty downstream rear outlet NOx Sensor with the WJIECO 19302360 NOx Sensor restores accurate post-SCR NOx feedback for SCR efficiency monitoring. Reliable downstream NOx readings allow the ECM to validate SCR performance, clear NOx and SCR related diagnostic trouble codes, remove engine power derate restrictions, and complete emissions readiness monitors required for state inspection. For Duramax owners who tow and haul, 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 Duramax owners and professional diesel repair facilities.

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

This 19302360 NOx Sensor is a true direct-fit replacement for the factory downstream rear outlet NOx Sensor on GM 6.6L LML Duramax 2010–2015. 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 ECM can run its SCR efficiency self-test and reset emissions readiness status.

Every WJIECO 19302360 NOx Sensor is fully bench tested before shipment. If you need a reliable 12V downstream rear outlet NOx Sensor compatible with 19302360 and Continental 5WK96645 for GM 6.6L LML Duramax, this WJIECO NOx Sensor will return your SCR emissions system to normal operation.
