2019 Mustang GT O2 sensor caused interesting codes

[Timken500]

My Edelbrock 2650 supercharged mustang wideband oxygen sensor on the right side failed and I don't know why it failed but it never threw an O2 code. it did however cause the car to misfire all over that bank of of cylinders. This is more of an FYI so others will know that the O2's do a lot on these cars. Car is now fixed with a new O2 sensor and everything is fine. Motor is fine and everything is good.

Codes that were thrown
P0300, P0302, P0304, P0306

Did your engine stall or have trouble starting?

Common. In certain failure manners they will not set dtc's, and the pcm will interpret the AFR reading as legitimate, and adjust fuel trims accordingly, which can cause a miss/missfire codes due to an excessively rich/lean condition.

Did it throw all these codes at once or did they pop up at different times. 19 gen5 whipple I'm have a po300 code and my tuners says it looks good in the logs and thinks it might be false positive. But no Specific cylinder just po300. Then the other day pulling out of gas station gave it a little nothing crazy. Look day a couple minutes later. Had po300 and o2 sensor reading slow code. My 19 is ridiculous with the codes. My 15 never had these problems. But the car runs great tho.

If you pull up the sensor data on a scanner, it will be pretty apparent that there is an issue even without a code for the failure present. An 02 sensor reading way to lean or way too rich will cause multiple misfires on the same bank, but not show a code for the sensor being bad. however if you look at datalogs you can see that there is an apparent issue with the readings.

My logs are clean. I'm just tired of the code. My car has some money In it and cant afford another problem. But the car does run great

What O2 sensor are you guys replacing it with? I assume the passenger side is longer so its best to have it on hand?
I have the same setup and no my MAF all of a sudden is going from a steady 1.08 at idle swingly wildly from .80 to 2.50 all of sudden.... I was gonna replace the brand new cars MAF ( since it's got a supercharger ford wont touch it ) then I thought what if my detonation issues were O2 sensor related not giving anything the right AfR? The car is even dying in me now because the lbs min swings do wildly its going from positive 15 to -31% on fuel trims....and yes I have misfire counts....
Trying to find a cheap alternative or something the parts store would have Rock Auto shows DY1442 but they are out....

No issues starting and it did not stall. Ran rough though

Yea threw them all pretty quickly

So, how do you know it is the sensor? In other words, did someone test and verify it failed?

I got mine at rock auto th

I saw it went to zero on my ngauge replaced the sensor and it fixed it.

I can second this. I had a bad O2 sensor replaced under warranty. Stock Mustang. NO CODES WERE THROWN. The only symptom was a slight misfire when idling. Took the dealership quite a while to diagnose. Ford sent an engineer down and everything. Lack of codes inhibits diagnosis since you really have to examine the logs.
