Walker Products 250-24253 oxygen sensor for the 2004-2006 Jeep Wrangler 6-cylinder 4.0L, the 2005-2006 Wrangler 4-cylinder 2.4L, the 2007-2011 Wrangler V6 3.8L, the 2012-2017 Wrangler V6 3.6L and other vehicles reads the oxygen content of the exhaust gas to show how efficiently the engine burns fuel. It is a narrow-band, 4-wire sensor made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace this sensor, rule out physical damage to its wiring harness and connector, which you can look over with the engine off and cool.
The vehicles it fits also include the 2011-2012 Ram 1500 V6 3.7L, the 2011-2013 1500 V8 4.7L, the 2011-2018 1500 V8 5.7L and the 2013 1500 V6 3.6L. It is also an 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.
Fit and size
Build and materials
This listing is one oxygen sensor, and the fitment lists one per application.
Is this the right Ram 1500 oxygen sensor for a 2011-2013 Ram 1500 V8 4.7L?
Yes, Walker Products 250-24253 is listed for the 2011-2013 Ram 1500 V8 4.7L. If your car is a different one, look it up on the Buyer's Guide tab.
Is this the right oxygen sensor for a 2008 Jeep Wrangler V6 3.8L?
Yes. The 2007-2011 Jeep Wrangler V6 3.8L is in the fitment, and the 2008 model year falls inside that run.
What thread size does the Walker 250-24253 oxygen sensor have?
Walker 250-24253 has an M18 - 1.5 thread. It is a narrow-band sensor with 4 wires.
How are the electrodes on this oxygen sensor protected?
The electrodes have a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
Can a bad oxygen sensor raise fuel use?
Yes, it can. A failed sensor can cause rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and newer vehicles may store fault codes in the ECU.
