P0133/p0153 codes

[5.0 Hatch]

I have P0133/p0153 codes that I can't seem to get rid of. From what I read is that it means the o2s are slow to respond. This showed up after I swapped in a 05 aviator long block. Zero changes outside of that.

I triple checked wiring, o2s are ntk brand with maybe 200 miles at most. I'm also running stock manifolds.

I also loaded the stock tune and no change.

I'm at a loss. Car runs great though.

Mine did the same thing. Switch the upstream O2 sensors to different sides and see if the code changes if it does the sensor is bad. Even then that is no guarantee. I never did solve my problem and eventually had my driver side run hot and break ringlands on #5 piston. Pull your plugs just for giggles and see if one side or the others plugs look different.

P0133 Possible Causes:

• Exhaust leaks
• Incorrect fueling
• Damaged MAF sensor (if equipped)
• Intake air leaks
• Contaminated HO2S11 (if equipped)
• Deteriorating universal HO2S11 (if equipped)

P0153 Possible Causes:

• Exhaust leaks
• Incorrect fueling
• Intake air system leaks
• MAF sensor (if equipped)
• Contaminated HO2S21
• Deteriorating HO2S21

I would think intake air leakage or MAF is something you haven't considered yet. Whatever it is, it is affecting both banks.

I had the 0153 flipped around the sensors and the code changed to 0133. Not sure what the cause was I replaced sensors and still no good. When I called ford they said in the oem sensors there was a right and left sensor not sure if that means you have to get an actual left and right side only or if they interchange. Anyway few months later my driver side was running hot/lean and ended up breaking ringlands. Hopefully after this rebuild we can figure this out.

Okay so I replaced my brand new ntk O2 sensors with Bosch. Cleared codes and still getting the exact codes. I'm convinced it's not the o2's at this point.

I'm not finding any exhaust leaks, intake leaks or anything obvious. Is it possible it's tune related now that I'm running 03/04 cams and still on the 01 tune?

Did you pull your spark plugs and see if one bank looks different from the other?

All looked the same. I replaced them as well

That’s a good thing as long as they all looked ok. When I had this code trouble the driver side bank looked slightly more lean than the passenger which resulted in broken ringlands. And could have also been bad or just inadequate fuel running 10:7.1 compression on 15# of boost.

These are from a key on engine off test,


From reading ford's manual on Po133/153

Says to run a second test.

Key on engine running.

Asked if p0040/0041
Po1127/1128

These are for

Upstream 02 plugs crossed and down stream plugs crossed. .

Wiring diagram will have these answers.

Rear is a lot easier to cross.

The color of the main wiring plug will determine location

It's certainly possible they are crossed since I did remove the engine. Maybe I should try disconnecting one and see which bank throws the code?

It says to run a koer,test

What everyone has already posted were common things to cause 02 codes ,

You already switched parts .and still have this code for both sides
These codes for 02 aren't for them actually being bad .
It's telling you what it's reading and what's happening,,

I'm just mentioning what Ford test would do .

It goes 2 ways ..

From if getting code or not with engine running test

No code it goes into having a short..
I see it hard to have a short for both sides ,,

Getting code and those saying swapped plugs is very much
The rear ..

If me ,,I would swap rear O2 plugs ,clear pcm and than see what you get. ..
If more codes it's easy to go back .

Look at this wiring diagram.
4 O2s,they all share 2 circuits than the other 2 circuits go to pcm .
Look at how yours is when under car.

Manual I used didn't show connectors for 01,
I'm familiar with 03 ,where the drivers rear is blue and passenger is purple

I'm sure the circuit numbers are still the same ,
But connector numbers are different than posted for 01

Issue resolved... I changed the o2s to OEM sensors which cycle way faster than the aftermarket. Also found a vacuum leak that was throwing off my stft on one side.

Where did you get oem sensors. Do you have a part number?

 

[DSG2003Mach1]

i was gonna say i managed to swap the front O2 harness around when I had the motor out, once it went open loop it would run like total shit for a minute or two before it stalled out and wouldn't start back up until coolant temps dropped enough to go closed loop again.

I pulled them out my trash pile of left over parts from when I did my aviator swap. They came with the engine I got from the salvage yard. Crazy that 20 year old OEM s nsors work better than brand new aftermarket

Part number Xc2f-9f472-a1a

 

[hotcobra03]

Crazy,,

Google search says OEM is made by Bosch ..

Keep up posted if codes reappear,
