o2 Sensors

[Ayee__Jay]

May be a dumb question but do people who are catless usually run into o2 sensor problems more than those who are catted?

Yes, they are very sensitive so when you are running "off-road" there's more carbon build up that will lessen the lifespan of the O2 sensor.

Rears ? No. Mines been like this for a year on E10, with octanium on occasion. Typical P0420 / P0430 codes. I couldn't care less if the CEL light is on so I don't use o2 extenders.

I had a ton of OEM o2 sensor problems when catted but running e85, now im catless whippled running e85 and switched to NTK 27079 for both upstream o2s and havent had any problem since.

Are you guys having issues with bank 1 or 2? I just noticed that bank 1 is out on my nGauge during a drive yesterday and I’m only at 5300 miles. Running catted LTHs.

From what I have gathered, E85 with LTHs is what often leads to increased 02 issues. This is usually due to the angle of the O2 sensor in the header as some brands have less of an angle which can lead to more moisture remaining on the sensor and subsequently leading to issues. Ideally you want the O2 sensor angled up slightly rather than parallel to the ground.

I had both banks fail 3x each on e85 before I switched to the NTKS, one side then the other with OEM cats and manifolds. No failures since I put in the NTKS , and I went catless and added a whipple but stayed on e85. Over 10k miles on NTKS these too.

Are the NTKS sensors the exact same, in terms of physical appearance, harness length and connector design?

I just did a search for vehicle compatibility and it says thst the NTK 27079 does not fit the 2019 Bullitt.

They have longer leads for header installation to eliminate extenders.
The part# is for Ford F-150’s. Guys have been swapping in these sensors for several years with zero issues.

They have excess wire but fit both upstream bungs and connectors and work great. I think they are more durable since F150 are flexfuel vehicles from the factory.

I may have spoke too soon, just had one o2 sensor go out. Running a burble tune on e85 boosted though. Still these lasted longer than the OEM type. I think I will be putting in the same ntk sensor anyway.

Just curious if you’re changing the both at the same time?

 

[Andy13186]

Ill just be changing one this time. its the bank 1 sensor 1. Ill have to see if somehow the wiring got messed up or try to find out what happened.

Did you have any luck getting it corrected? I'm running into this issue. P2251 code- O2 sensor negative current control circuit open...replaced the O2 with an OEM unit and the extensions look fine. No sign of excessive heat or anything and no other DTC's. Still getting the same code even with the new O2. Thinking it's a wiring issue somewhere. If anyone has any advise, I'd appreciate it.
