A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a malfunction indicator light, and other faults can produce the same signs. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage before replacing the sensor. This listing is one sensor, and each sensor position on the engine takes one.
Fits
This direct-fit oxygen sensor for the 2012-2021 Jeep Grand Cherokee V8 6.4L, the 2013-2022 Grand Cherokee V6 3.6L and the 2018-2021 Grand Cherokee V8 6.2L also fits the 2011-2013 Ram 1500 V6 3.7L or V8 4.7L, the 2011-2018 1500 V8 5.7L, the 2013 1500 V6 3.6L and many other vehicles. It also works as an oxygen sensor replacement for the 2012-2017 Jeep Wrangler V6 3.6L. If your car is not named here, open the "Vehicles it fits" section and look up your exact model and engine.

Frequently Asked Questions
Is Walker Products 350-34039 a Ram 1500 oxygen sensor for 2011-2018 trucks with the V8 5.7L?
Yes. Walker Products 350-34039 is listed for the 2011-2018 Ram 1500 V8 5.7L, and each sensor position takes one.
Will this work as a 2008 Jeep Wrangler oxygen sensor on the V6 3.8L?
Yes. It is listed for the 2007-2011 Jeep Wrangler V6 3.8L, which covers the 2008 model year.
What thread size does the Walker Products 350-34039 have?
Walker Products 350-34039 has an M18 - 1.5 thread. It is a four-wire narrow-band sensor.
Can a bad oxygen sensor turn on the malfunction indicator light?
Yes. A failed sensor can illuminate the malfunction indicator light, and newer vehicles may store a fault code in the ECU for the affected sensor.
How does the coating on this Walker Products oxygen sensor protect it?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes use a gas-permeable platinum layer.
