PAT EGO-138 Exhaust Gas Oxygen Sensor

Is your engine not running as smoothly as it should? Noticing poor fuel efficiency or an unexpected check engine light? A faulty Oxygen (O2) sensor could be to blame. These crucial components help maintain engine performance, fuel economy, and emissions control. We offer a wide range of high-quality O2 sensors to keep your vehicle running efficiently.

O2 sensors play a vital role in fuel-injected vehicles by analyzing the air/fuel mixture in the exhaust. This data is sent to the Engine Control Unit (ECU), which adjusts fuel injection for optimal combustion. The sensor continuously fine-tunes engine operation to ensure peak efficiency.

There are two main types of O2 sensors: narrow band and wide band. Narrow band sensors, commonly found in older vehicles, provide basic feedback on whether the fuel mixture is too rich or too lean. A failing sensor can cause poor fuel efficiency, rough idling, and cold-start issues.

Wide band sensors, used in modern vehicles, offer real-time, precise data to optimize engine performance across all RPM ranges. If a wide band sensor fails, it can trigger limp mode, reduce engine power, and activate the check engine light, requiring immediate attention.

We stock an extensive selection of O2 sensors compatible with nearly all fuel-injected vehicles. Whether you drive an older model or a late-model car, we have the right sensor for your needs.

Don’t let a faulty O2 sensor impact your vehicle’s performance. Shop our selection today for reliable solutions that help keep your engine running at its best.
