2020 Buick Envision Oxygen Sensor HYR844VL

Product Description

This oxygen sensor is designed to monitor exhaust gas oxygen levels and help maintain the proper air-to-fuel ratio for efficient engine operation. A failing oxygen sensor may lead to reduced fuel economy, rough engine operation, increased emissions, or an illuminated check engine light. Replacing a worn sensor helps restore proper engine function and overall drivability.

Built with durable materials and precision sensing technology, this oxygen sensor delivers accurate readings under demanding driving conditions. The sensor responds quickly to changes in exhaust composition, helping the engine control module adjust fuel delivery for efficient combustion and reduced emissions.

Engineered as a direct replacement for select vehicles, this oxygen sensor offers proper fitment and straightforward installation. It helps support fuel efficiency and reliable engine operation.
