Product Features
TRQ oxygen sensors are manufactured to precise specifications using premium raw materials to optimize your vehicle’s emission system. Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.

Yes, this is able to fit and it is only for the upstream.
These sensors will only fit the downstream position of your vehicle. The upstream sensor can be located under part number: WKEOS00037
Yes they are the same.

This will display parts guaranteed to fit your vehicle. Just be sure to verify all of the information shown in the Vehicle Fit tab before ordering.
There are four O2 sensors in total. There is an "upstream" and a "downstream" O2 sensor on each exhaust that extend from the engine. The "downstream" sensors are easy to locate by crawling underneath the vehicle (a foot or so behind the front tires). The "upsteam" sensors are further up, closer to the engine, & difficult (but not impossible) to reach. The "upstream" one on the drivers side was especially difficult as the plug is up in the engine bay. I accessed the plug from above in the engine bay. There are several helpful videos on Youtube. I used an offset wrench, no need to buy special O2 socket.
These sensors are not listed for the 4.7L.
These parts are listed to fit both the upstream and downstream location of the 2006 Jeep Liberty.
Thank you for your inquiry. The fit of these sensors will vary dependent on the vehicle. Please provide us with your year make and model so we can confirm the fitment, thank you!
