I had a code pop up saying left front speed sensor not reading.
I replaced it.
Next day the lights where back on and said left front again - then the wheel bearing imploded!!! Like bad! so I replaced it. And the light came on again:
replace the sensor again thinking maybe it was collateral damage to the bearing going… same issue same wheel.
any ideas?
gap iid shows no speed being read on that wheel either.

thanks in advance guys and gals!

 

So how bad did the bearing go? I would take a really close look at all the wiring looms. You may also want to examine the half-shaft, it has the toothed ring. I may be possible the bad bearing caused the toothed ring to gouge into the knuckle.

 

if it was a buggered half shaft would it read sometimes and then go dead?
when it reads it’s right in step with the other wheels- not off or sporadic
also now it’s saying my transmission is overheating and slow down when I start the truck up

 

Irrelevant, check for damage.....

 

trans temp is irrelevant or sporatic readings?

 

Well if you add info AFTER I respond....

Good luck.

 

Must be a lag on my end- apologies.

 

After checking again and poking around and running through the steps of install… no visible damage on the halfshaft or knuckle. Wires are clean and connector is good and clicks on the speed sensor. Wires going into the harness look in new condition. No knicks or anything.
Sprayed it all with air. Put it back together and no lights.,, until 1/2km up the road. Then they all came back.
could this be trans temp related as that’s now popping up?
all my lights are working and the gap iid shows my brake switch functioning

 

Brake light switch and all tail light bulbs replaced… what else is there to eliminate?
it has started to engage the abs when making a turn from a stop- not allowing me to go anywhere…
any other suggestions with where to look?
