HOW TO: Jeep Grand Cherokee O2 Sensor Replacement (2005-2010 WK)

Replacing a faulty O2 sensor on your 2005-2010 Jeep Grand Cherokee WK is one of the easiest things you can do yourself, and I'll walk you through it. Don't spend $200+ on this at the dealer. Instead, watch this detailed video and save yourself some dough.

Part Needed:

Tools Needed:

As shown on a 2008 Jeep Grand Cherokee Laredo 4x4.

The Jeep has four total O2 sensors. And they tend to go bad around the same time.

Thanks for watching!

Great video. I really appreciate that you showed it was a push connection, in low visibility areas it can be hard to determine.

Tip: if you need to replace the O2 sensors after the catalytic converter for emissions B1/S2 or B2/S2 put the new O2 sensor in B1/S1 or B2/S1 which measure air/fuel ratio (if you have easy access to it), a new one will give you better fuel mileage, put the old working O2 sensor in B1/S2 or B2/S2 which only measure emissions and do not adjust air/fuel ratio..

Excellent video. Please keep it up, especially for this 05-10 Jeep Grand Cherokee generation.

My Jeep was going into limp mode because of the sensor and i was able to change it thanks to this video ! I ordered the same Bosch model you have in the video but they look different now but they’ll fit. Thanks !

Fyi, for others watching I don't believe you have go through the "code find" process with a device. Prior to getting getting OBDII devices (when a check engine light came on), I turned the ignition off and WITHOUT fully starting the engine, turned the key in the ignition. So flip on & off THREE times to the position just before igniting engine to where you see the dashboard light up and hear all the beeps and it should clear the dashboard and show you the code (P####) where you would normally see the temperature, distance, tire pressure, etc. This was with an 05 GC 5.7L. I'm not sure the range of models and trim this worked on.

However, a plug-in OBDII reader that connects to your smart is relatively cheap. I got one for $10 on Amazon. Since then, I have also purchased a handheld device which gives other pertinent information depending on how far you go into diy vehicle work. If I'm not mistaken, a device that plugs in is the only way to clear a code other than fixing the issue and driving enough miles for the computer to analyze and clear it itself. I have just recently jumped in diy stuff so if something is incorrect, please clarify. I don't care to be wrong, it's better to have as much correct info out there as possible for others to use.

Nice video and thank you. In my 2010 hemi WK, it wasn't that easy. Well, sensor 2, bank 1 was easy, the other three had the plugs buried up above the transmission and firewall. I was able to get Sensors 1, 2 bank 1, and sensor 2 bank 2 done, but sensor 1 bank 1 (passenger front) is impossible to get to without taking out the exhaust. I recommend just unbolting the exhaust from the header to the middle collector and do all four that way.

Thanks for the video keep doing more for this generation

[ОлегВасильев-бт]

Please !!!show how to remove sensor 1 bank1 (0032 error).

[Thatdudebigttv]

damn my boy even used a torque wrench . im impressed lol
hope this job goes this smooth for me . i gotta change all 4

[Bushmaster]

Thank you just finished, no telling how much you saved me. 3/8 to 1/2 is the way to go also.

[galaxie]

Great video, I think I'll try and do this. I like those ramps also.

[mathermp]

Cut wire on old to make life easy. NTK is oem match. I have heard of issues with bosch in mopar vehicles.JS.. Nice video. thanks

[robertweinstein]

I have no problem get the sensors out of the pipe. I can’t get the connectors apart

[livenfree]

Very clear. Through. And to the point.

[bennyreyes]

Good video 👍 Looking at it how do you did it with the socket then I had an idea... I'm going to buy a regular 22 mm socket and then I'll make a vertical cutting as the original !💪

[susanscovill]

My 5.7 has four. Are they all the same part and just located in four different areas?

[mickzupan]

Ahhh The upstream is crazy hard for me at least on the 3.7 the one on the driver side, I finally got it out, but I cant get at the connector.

[HarleyPebley]

Good, thorough video.
Doing a bit of research, looks like there's either 2 or 4 O2 sensors depending on whether it's Federal or CA emissions compliant. Need to go look to see what I have.
Thanks!

[pgreenlaw]

My 2010 with the hemi has the sensors DIRECTLY on the body of the cats themselves. I can't get to either of them for the life of me. The connector is right almost on top of the tranny and that's even worse. This sucks.
