What does DTC PO153 mean?

[bjbrowder]

Ive looked up what the code means, upstream circuit slow response bank no 2. But i dont know what that means.
Both my o2 sensors are fairly new, and they are from Ford ( $75 each ). I replaced them both when i put on the JBA longtubes.

Did you get a tune for the longtubes? If not, do you have an exhaust leak? If it's neither of those problems, swap o2 sensor from bank one and see if it follows the sensor or stays on bank 2.

If you have never run leaded gasoline it is most likely a tune related issue.

 

[bjbrowder]

Yes I have a tune for the long tubes, and I run 93 oct Non Ethanol gas in every tank.
I get that DTC code about once a week.

I get that same code from time to time after my LT install.

Probably from the placement of the rear O2's in the header - further away from the exhaust port.

 

[bjbrowder]

So its not something to worry about?

 

[rayS197]

I dont lose any sleep over it if thats what your asking. Ill bring it up to my tuner next time im there for my converter etc..

It just means that due to the move of the front O2 sensor from the stock manifiold to farther away with the longtubes, it didn't heat up as fast, you may see it every so often when cold, I have seen it once in 2 years, cleared it and it never came back. You are fine, nothing to worry about

 

[bjbrowder]

Ok, thanks guys i appreciate it.

WOULDN'T you know it, a day after commenting, I got the code today. Code cleared, back to running like a champ!!

Thanks for the curse BJBROWDER!!

I've had mine since day one of my long tubes..... Bbr sent me a updated tune and I still get it........ Hope they can get it right when I put the cams in ... I have some faith

It may have been a tune issue with you guys and BBR, but it is not always directly related with a tune being off
