Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello and welcome!My name isCustomerand I can assist you with your question.
Thanks for requesting me! I dont have a listing for this code. Could it be P0420 by chance?
I just looked in your history and saw the question were we worked together last time. It was a P0442 which is for the evap system. Is this what you are talking about? Are you trying to get an evap issue? Which sensor are you talking about? Vent valve, purge etc...?
Thank you for that information. Which sensors are you talking about? From what manual? Can you upload a picture? And what exactly is your question. Are you looking for the location of a particular sensor?
Sure, but I need to know what components or parts your talking about to provide you with their locations.
Got it! So you found one or two of them and you need to find the other one or two?
Please send me your VIN so I can get you some more detailed pics.
Sure thing.. one minute..
It looks like your vehicle only has two oxygen sensors. Only california emissions jeeps this year have three oxygen sensors. Here are the part numbers for yours.
I have attached a pic. It is the drawing on the left.
Keep in mind, the oxygen sensors are not for or related to the evap system. Replacing them will not fix your P0442 code.
Here is a diagram of your evap hoses.
Any of them should be able to get these parts. I would call around first to see if they have them in stock. If not, they should be able to get them the same day or next business day for you.
I am glad I can help!

Your welcome. Thank you and have a great night!
How many converters do you have?
Can you upload some pictures?
Does it look like the picture on the left or the right of the diagram I sent?
You bet! Your welcome!
Thanks for the heads up!
Ok, can you upload them or send me the links?
No sir I did not
YES, sending over my number now..
Ok, got the videos! Thank you very much!
It looks like you have california emissions.
Do you have two more oxygen sensors on top?
Look at the picture I sent you. Look at the diagram on the right. There are a total of 4 oxygen sensors. Two below and two after the converters.
NO sir. Not that I am aware of. I think if you lower the truck down and look on top, you will see two more oxygen sensors inside the exhaust system coming right out of the exhaust manifold.
Sounds good! You too!
