I was getting P-0133. Slow responce from oxygen sensor. I had the O2 sensor replaced and still get the same code. Any other ideas. They told me it's usually the catalytic converter. They want $500.00 to replace the converter. I hate to just start replacing things. The thing that sucks is I have to go through emissions testing this month.
Thanks,
Craig

 

Got any specs on the truck ( your profile is empty ).

Engine size.
MY
Trim level just in case there is a wiring difference.
Cab type.

PS : Fill out your profile, so next time the info is available straight away.

 

Done. It's a 2000 5.4 2wd XLT Supercab.

 

which o2 sensor which bank was it bank 1 or 2

 

It ain't the coverter. The cat cannot cause this code.

Assuming they replaced the correct (Upstream, passenger side) side, you'r left with a possible vacuum leak or an exhaust/manifold leak that is specific to bank 1 only.

If this was an independent shop that did the previous, I'd suggest taking to a Ford dealership that has a good diagnostic technician who actually understands the systemand has the proper tools and test procedures to diagnose and repair it properly.

I'm sorry I am getting P-1331 code now.

 

P-0133 is bank 1 sensor 1 which is the front o2 sensor on the drivers side.. you replaced the wrong one if you already replaced one

 

hang on i have a list of all codes let me boot it up

 

I was getting P-0133 and i was told it's the passenger side one. So that was replaced. Now I am getting P-1131.

 

I also read this http://autotechrepair.suite101.com/a...r_flow_sensors

 

its on the drivers side... i know what im talking bout

 

I am not trying to argue or anything, but all the searches here say bank 1 is the passenger side.

 

after looking at this diagram i got... turns out i was wrong.. your right its on passenger side... but which did you replace... the front or back... the each are different ones heated and ones not...

 

I replaced the front one.

 

if you still gettin a o2 code on the passenger side your back one has gone bad also.. replace it to... me i just replacedall 4 of mine at once so i didnt have hunt anything with a good buddy working at partstore and a cousin working for ford i get one hell of a discount so it just money ... spend it
