Standard Ignition NOX051 nitrogen oxide (nox) sensor for the 2020-2021 Chevrolet Silverado 4500 HD V8 6.6L and other vehicles measures the nitrogen oxide level in diesel exhaust. It is made for the upstream position.
A failing NOx sensor can show up as an emissions warning light or a failed emissions test. Before you replace the sensor, rule out damaged wiring, a loose connector and other emissions-system faults that can set off a similar warning; a shop can test the sensor itself. The upstream position takes one sensor, and this listing is a single sensor.
Standard Ignition NOX051 is a direct-fit OE replacement for the 2020-2021 Chevrolet Silverado 4500 HD V8 6.6L, the 2020-2021 Chevrolet Silverado 5500 HD V8 6.6L and the 2020-2021 Chevrolet Silverado 6500 HD V8 6.6L.
