Keep tabs on nitrogen oxide in your diesel's exhaust with the Standard Ignition Diesel Nitrogen Oxide (NOx) Sensor NOX047. This downstream sensor reports NOx levels to the engine control system. It is a direct-fit replacement for many vehicles, among them the 2020-2022 Chevrolet Colorado 2.8L, 2020-2022 GMC Canyon 2.8L and 2020-2022 Chevrolet Express 2500 2.8L; see the "Vehicles it fits" section for the full list.
- Direct-fit OE replacement: Designed for easy installation and to support proper emissions-system operation on the listed applications.
- Built for harsh conditions: Made from high-quality materials intended to withstand extreme conditions.
- Tested for reliability: Each NOx sensor undergoes extensive testing aimed at dependable service.
- Controlled manufacturing: As a global manufacturer of aftermarket automotive products, Standard Ignition maintains complete quality control throughout its manufacturing process.
Specifications: The sensor has one rectangular female connector with six male pin terminals. It installs in the downstream position, and the listed applications use one sensor. Country of origin: United States.
Signs this part may need replacing: These include a check engine light, stored NOx sensor trouble codes, or emissions-system warning messages. If a failed downstream NOx sensor is the cause, NOX047 replaces it. Diagnose the fault first, because wiring or other emissions components can produce similar symptoms.
Interchange: NOX1047 · DNX1047 · 24001918 · 55499763 · 55509173 · 55509678 · DNX047

Frequently Asked Questions
What does a downstream NOx sensor do?
It measures nitrogen oxide levels in the exhaust at the downstream position. It sends that reading to the engine control system, which uses it to monitor how the emissions aftertreatment is working.
Which vehicles does NOX047 fit?
It fits many vehicles, among them the 2020-2022 Chevrolet Colorado 2.8L, 2020-2022 GMC Canyon 2.8L and 2020-2022 Chevrolet Express 2500 2.8L. See the "Vehicles it fits" section for the full list.
What are signs this NOx sensor may need replacing?
Watch for a check engine light, stored NOx sensor trouble codes, or emissions-system warning messages. Diagnose the cause first, because wiring or other emissions components can produce similar symptoms.
What connector does NOX047 use?
It uses one rectangular female connector with six male pin terminals.
How many sensors do I need, and what numbers does it interchange with?
The listed applications use one downstream sensor. It interchanges with NOX1047, DNX1047, 24001918, 55499763, 55509173, 55509678 and DNX047.
