    Replacement for Malfunctioning Oxygen Sensor. The O2 sensor, also known as Lambda probe or sensor, is a critical component in modern automobiles. Your Jeep uses these sensors to check how well combustion is taking place inside the engine, maximizing performance while minimizing emissions and protecting the cats from the effects of poor fueling. This Oxygen Sensor from Crown Automotive is the perfect replacement if your 4.0L TJ Wrangler’s front pre-cat O2 sensor has stopped working properly.

    Premium Quality Materials. The Oxygen Sensor lives in a really tough place under your car on the exhaust system, where it deals with very high temperatures. Crown Automotive manufactures the Oxygen Sensor from premium-grade metal and plastic to ensure it lasts many years.

    Direct Factory Replacement. The Crown Automotive Oxygen Sensor is a direct replacement for the original stock component. It is designed simply to screw into the existing bung on your Jeep’s exhaust and connect to the vehicle wiring harness.

    Limited 12 Month Crown Automotive Warranty. The Oxygen Sensor is covered by the Crown limited warranty, which lasts for 12,000 miles or 12 months.

    Application. The Crown Oxygen Sensor fits the front, pre-cat position on the exhaust of the 4.0L Jeep Wrangler TJ models from 2001–2003.

            Perfect solution

            Jeep was running weird. Once I installed this, it completely fixed the idle and acceleration problems.
