LAMBDA PROBE

The Hella 7.05271.67.0 is a downstream oxygen sensor designed for select Nissan and INFINITI vehicles. It directly replaces OE No. 226A0EN21A and covers multiple positions including downstream, downstream left, and downstream front. This sensor is part of the Pierburg line, distributed by Hella.

This oxygen sensor is crucial for emission control system service, providing accurate data on exhaust oxygen levels to optimize engine efficiency and reduce emissions. Common reasons for replacement include check engine lights related to sensor performance, fault codes tied to downstream sensor issues, or failed emissions inspections.
