Hey guys new to this forum. I have a 2008 XB with about 43,000 miles on it. The check engine light came on about 1 month ago and I reset it by unhooking the battery hoping it was nothing. It stayed off for about 2 weeks but has come back. I pulled the codes today and they are:

P0354

P2237

P2238

I have e-mailed a local dealer to see what they have to say about it. Any insight as to what is going on? I half way consider myself a shade tree mechanic and would like to fix myself if possible. Any help is greatly appreciated.

 

Coil pack(s) and 02 sensor failures from what I found out using google.

 

Time for a new wiring harness?

 

is that what it is.. mines came on but never pull the codes yet..

It sputters for a while than it runs ok.. than the light goes off. I get back in the car and CEL and Traction light on.. and here we go again..

Wiring harness issue?

is your friend.

 

None of those shows any codes anywhere in them. So not sure what you are trying to say. I am not new to forums and I do search but random threads do not help.


edit:
Unless you are referring to the stuttering above your post then it makes a little more sense.

 

I have read about the wire harness problem. Is this a job that I could do myself? I have not found a part number for it yet. Does anyone know it? Would be nice if it was only a coil pack and an O2 sensor but I have my doubts after reading about the wire harness last night. Would the wire harness be covered under the 5yr 60k mile engine and powertrain warranty?

 

Yes, I was referring to the post above mine.


Yes, it would be covered.

 

Just got off the phone with a service rep. Going to take the car in Thursday morning for them to run the codes themselves. He said a C.E.L. may or may not be covered under the power train warranty. I asked him about the TSB for the wire harness and he said he was not familiar with it and that some TSB's are covered under warranty and some are not. I guess I will find out more Thursday. Now I just need to drive the car and get the light to come on again. I reset it with the code reader the other day and he said it is best if the light is still on.

 

The light finally came back on and the wife took it to the dealer today. He said the #4 coil pack needs replaced but he said it is not under warranty. I had her to ask about the powertrain warranty and he told her that anything that is touched by a liquid is not covered under warranty. I then informed her to get in the car and drive away. They never mentioned anything about the code for the O2 sensor that I got. I still think it is probably a bad wire harness. They wanted 2-$300 to do the repair. I have not seen the list but she said he was going to print everything out. She mentioned that he wanted to do some fuel cleaner process that cost over $100. From everything I have ever read that is one of the biggest rip offs they hit you with.

Anyways looks like I will be replacing the coil pack myself, anyone on here ever done it?
