Standard Ignition Nitrogen Oxide (NOx) Sensor P/N:NOX001
Standard Motor Products
Standard Ignition NOX003 nitrogen oxide (nox) sensor for the 2015 Chevrolet Express 2500 V8 6.6L and other vehicles measures nitrogen oxide in the exhaust of a diesel engine.
A dash warning light or a failed emissions test can mean this sensor has worn out, though a damaged wiring connector or an exhaust leak can be behind the same signs, so find the cause before replacing it.
This downstream diesel sensor is a direct-fit OE replacement for the 2015 Chevrolet Express 2500 V8 6.6L, the 2015 Chevrolet Express 3500 V8 6.6L and the 2015 Chevrolet Express 4500 V8 6.6L. It is sold individually, and the fitment calls for one per vehicle.
