Are these upper or lower?Robin S.Sep 23, 2024
Best Answer:Hi Robin, thanks for initiating contact. This is an upstream sensor. Upstream oxygen sensors are typically located before the catalytic converter in the exhaust system and are responsible for monitoring the level of oxygen in the exhaust gases to help manage fuel efficiency and emissions.

Replaced the o2 sensor with this new one and it took care of the o2 sensor code. Works perfectly.
