Oxygen Sensor Replacement

What is an Oxygen Sensor?

An oxygen sensor monitors the amount of oxygen in the exhaust gases of your vehicle. It helps the engine control unit (ECU) adjust the air-fuel ratio, optimizing fuel efficiency and reducing harmful emissions. A faulty oxygen sensor can affect engine performance, reduce fuel economy, and increase emissions.

Quality and Brand Differences

When replacing an oxygen sensor, you should consider both the quality and the brand. Here's a comparison:

• OEM (Original Equipment Manufacturer) Sensors: These sensors are designed to fit and perform just like the original ones. They offer a high level of reliability and typically come at a higher price.
• Aftermarket Sensors: These sensors are generally more affordable and may come from third-party manufacturers. While many meet or exceed OEM standards, there can be variability in quality.
• Top Brands: Popular oxygen sensor brands include Bosch, Denso, NGK, and ACDelco. Bosch and Denso are known for their high-quality, long-lasting sensors.

Labor Replacement Cost for Oxygen Sensor
