O2

[Jakever]

I just got 04 Renegade and I need new O2 s my question is my wife had s Chrysler Pacifica and I Swaped all of them out and a couple days the light came back on and same codes after clearing the first time. The issue I was told was Chrysler's hated after market sensors. So I had to go to the dealer and pay a lot more for Dodge parts. It did fix it though. Has anyone had to buy O2 s like this for these jeeps or standard ones at the part store work?

Dealer O2 sensors aren't necessary but NGK sensors work well. DO NOT buy Bosch sensors - you'll deal with having to replace them in short order.

What bob said. Good luck on bank 1 sensor 1 though. That's a real pain.

OE O2 sensors for the KJ are made by NTK(part of NGK) so you can use NTK O2's from parts stores with no worries.

Well new issue the light went off had it scanned no active codes but did show bank 2 sensor 2 lean in history. I had to replace a fuse for the dash backlights this morning. Now no CEL. It comes on at start up then goes off just like it should. Weriod.

Hope it is not as bad a F150 spark plugs!

No - nothing like that job! :favorites68:

Have to contort yourself a bit to get to it but as long as the exhaust manifold is cooled down you can get in there.

I hear people complain all the time about replacing components in Jeeps but Ford's F-150 plugs and GM's diesel injector replacement projects make work on a Jeep look like playing with tinker toys. The injectors on my brother-in-law's GM 3500 Cummins needed replaced and they had to tear out the wheel well to get to them. It was a $4500 bill! And the way the plugs break off on the Ford engines is unreal...

I can't think of a single part of my Jeep that I can't replace in my garage and I've got nothing special as far as garage space, tools, etc. Probably the cheapest vehicle I've ever owned as far as cost of maintenance.

You all mentioning those nice Ford plugs that like to break,there is a new trick that you rarely ever have a plug break and it's fairly quick.

Run the engine for a good 20-25mins,so at operating temp,then shut off and start right away with passenger side rear most plug working your way forward on that bank.Then start on the drivers side rear plug and work forward.Only remove the plugs,do not install new plugs yet.Never broken a plug using that technique.

Same here, 'cept maybe lifting a motor or dropping a ******.

Agreed, Bob. Not much a set of jack-stands and basic mechanics hand tools cant take care of on the KJ.

Lifting the engine, not bad with an engine hoist. I paid $130 for a bright orange one at Harbor Freight about 8 or 9 years ago... pulled and dropped in about a dozen engines with it.

******? Nothing that a cheap hydraulic floor jack can't handle..

Probably the most difficult "repair" you could have to do on a KJ (and maybe other models too?) would be tracing down and correcting wiring and electrical gremlins. But that ***** on any vehicle.

I just replaced the downstream 02 sensor on the wife's car . I found the OEM NTK sensor on ebay for about half of parts store price .
