OK, well ill start with this. I pulling codes p0134,p0135,p0154,p0155,p0101.
The problem being I have replaced the o2 sensors to start with but still getting the same codes. I'm wondering if i don't have a wiring gremlin somewhere or some fuse that i don't know about. I have checked fuse 2 under the hood and its fine. I was wondering if anyone has had the same problem or similar and what I could look for and where to look for it. Any suggestions are appreciated. Thanks

 

So you have 2 issues showing, both front 02 are dead as is your MAF.
When you installed the new 02, did you replace all 4, did you make sure the connections were free of grease or oil?
As for the MAF, you need a new one., make sure to not buy an aftermarket or Generic Bosch but one with matching part numbers or it won't work.

 

Yes i replaced all 4 and yes i cleaned them up with electrical cleaner but still the same codes thats why i have not replaced the maf. Im thinking they are linked in some way, far as wiring goes.

 

They aren't linked together. I know this will be a silly question, did you clear the codes after replacing the 02's, whos did you install and were they generic or did they have plugs on the wires?

 

Just out of curiosity...Which code pointed you to the MAF? I have a similar problem P0134, 135, and 155. I have replaced all the o2 sensors with Bosch that had plugs on them. My next move was the MAF. I also have P1590 but think it's unrelated.

 

I did a test on my MAF by pulling plug from it, and it stayed running..
Then I tried again a few minutes later and the truck died immediately...

MAF is a $200 part.. how can I be sure this is the faulty component??

 

IS this a simple arrow pointing to my problem??
