Why O2 Sensors Need to Be Replaced
O2 sensors are an important component of a vehicle's emissions control system. They monitor the air-fuel ratio in the exhaust and send this information to the vehicle's computer, which then adjusts the fuel mixture accordingly. Over time, O2 sensors can become worn or damaged, leading to decreased fuel efficiency, increased emissions, and potential engine problems.
Replacing the O2 sensors at the recommended intervals is important for maintaining the vehicle's performance and meeting emissions standards.
