The 84422750 is a genuine New Holland NOx (Nitrogen Oxide) sensor designed for precise emission monitoring and control in agricultural machinery. This critical component ensures compliance with emission standards and contributes to the efficient operation of the engine's exhaust aftertreatment system. It is specifically compatible with various New Holland T7 series tractor models, including T7.165S, T7.175, T7.190, T7.210, T7.225, T7.230, T7.245, T7.260, T7.270, and others, as well as Case IH Puma series tractors. Replacing a faulty NOx sensor with this OEM part helps maintain engine efficiency and prevents diagnostic trouble codes related to emissions.
