Standard Ignition NOX052 nitrogen oxide (nox) sensor for the 2021-2022 Chevrolet Silverado 4500 HD V8 6.6L and other vehicles measures nitrogen oxide in the diesel exhaust. Mounted downstream, it sends that reading to the vehicle's computer for the emissions system.
- Diesel NOx sensor for the downstream position
- Rectangular female connector with six male pin terminals
- Materials chosen to withstand extreme conditions
- Extensive testing for reliability
- Quality control maintained throughout the manufacturing process
Quick facts
- Part: Standard Ignition NOX052 nitrogen oxide (nox) sensor
- Fits: 2021-2022 Chevrolet Silverado 4500 HD V8 6.6L and other vehicles
- Position: Downstream
- Condition: New
A check engine light or an emissions warning can mean the NOx sensor is failing, but a damaged connector or wire can trigger the same lights. With the engine off and cool, look over the plug and wiring for corrosion, cracks or a loose fit before you replace anything. This listing is a single sensor, and the downstream spot on these vehicles takes one.

Frequently Asked Questions
Is the Standard Ignition NOX052 NOx sensor right for the 2021-2022 Chevrolet Silverado 4500 HD V8 6.6L?
Yes. Standard Ignition NOX052 is a downstream diesel NOx sensor that fits the 2021-2022 Chevrolet Silverado 4500 HD V8 6.6L.
Is the NOX052 an upstream or downstream NOx sensor?
Downstream. Standard Ignition NOX052 is listed as a downstream-position diesel NOx sensor.
How many pins does the NOX052 connector have?
This NOx sensor has one rectangular female connector with six male pin terminals.
Can a failing diesel NOx sensor turn on a warning light?
Yes, it can show up as a check engine or emissions warning light, though other emissions parts can light them too. A shop can scan the codes and test the sensor.
Does Standard Ignition NOX052 replace DNX1052?
Yes. Standard Ignition NOX052 is cross-referenced to DNX1052; the Interchange line lists the other numbers it replaces.
