It has been a few months so, what the hell... My vehicle decided to light up those same lights! I wish I could just rip the entire ABS system out of this thing! I F'ing hate it!
To add a new twist to the problem... I just bought a Bosch Scan 1150 tool to look in to some ABS codes. I had 3 codes present but it says "No DTC definition found. See service manual" for each of them.
I cleared the codes but they just came right back when I started driving. (I did start another thread about this) I will go to Advance Auto after work to try their code reader to see if mine is not working properly. I will let you guys know.
I am willing to bet it is the same damn front right speed sensor/metal stuck to bullshit I have been dealing with for some time. But I do not know... Hopefully the scanner is working right.
If it is, I am willing to bet it is a bad wheel bearing or hub causing some wobble which eats my sensors. Could this be accurate? At this point, whop knows.
All I know is that I am sick of throwing money at this BS ABS system for the same damn problem over and over.

Wow, I’d be losing it if I were you. This IS ridiculous.
There is a ring in there that gives the sensor its input. Wonder if that could be it? Just a wild guess. I’d say odds of that are pretty low.
99% of intermittent electrical problems are due to shorts. Seems stupid, but mine was caused by a loose/broken harness connector. Duct tape and a zip tie keep it together. Juggle the harnesses. Any looseness you find, secure it. Would only take 5 minutes and can’t hurt.
You may have a short in the wires between the sensor and the ABS unit also. Hard to diagnose these intermittent problems.
Electrical problems are the most frustrating ones!

After an hour on the phone with Bosch's tech support I said screw it and just returned the scanner.
I had the codes read at Advance Auto and it is indeed the front right ABS wheel speed sensor. AGAIN! "Metal stuck to"
Now the plan is to look in to the bearings and hub. It must be a mess in there or on the verge of failing. That is my best guess anyways as to why this sensor needs replacing after every 3 months or so.
How did you know exactly which one it was? All their scammer told me was sensor “A.” I’m fighting this problem now after buying from a small used dealership, prolly why it was there in 1st place. Thanks!

The scan tool I borrowed at Advance Auto Parts told me exactly which sensor it was on the display. Strange yours just said "A". I did end up buying another scan tool. It is Actron. I do not recall the model but this scan tool worked and gave me the same results. I will keep this one.
The hub assembly on mine ended up being the problem.

I totally understand your frustration, however it usually ends up being our stubbornness with these trucks when it comes to fixing them. When it said metal stuck to sensor it was your trucks way of literally yelling at you whats going on with it.
I recently rebooted by driver side CV.. when it buttoned it all back together by lights were on.. I was careful with the wires and everything and somehow it still happened. I replaced the harness assuming that was for sure the issue of broken wires inside with no luck. I popped the sensor out of the hub and noticed the sensor was sheered off on the tip clean.
Swapped sensors and the code changed to the other side, so it should be resolved when the sensor gets here from amazon.

Soooooooo... I have replaced the harness and the sensor.. The sensor I replaced was physically cracked.. so I was confident that would be the culprit.. the lights remain.. running out of ideas..
