Tundra ABS/Wheel Speed Sensor

Took my 08 Tundra to a shop for my abs/traction/4 Hi/4 Lo etc .... On or flashing and they told me my backing plate wasn't there and that is what is causing my lights, but if I am thinking is the backing plate has nothing to do with my abs/wheel speed sensor

 

I just had and fixed this problem. There was some water build up in my front diff actuator.

Follow this youtube video and it should fix your problem.

Of note, the circled part comes off easily. Mine came off and I was lucky to find it. When you're reinserting the gear, you can use a ziptie to hold the hear in place, once you install the cover, cut the ziptie, pull it out, and then secure it to the front diff. If you need pictures I can provide some.

 

Thanks I'll have to try that, my lights is abs on traction on, 4hi 4 low and VSC flashing, they don't stay on constantly they just randomly come on.

When my lights aren't on 4wd hi and lo work as they should

 

Update, the shop I took it to is garbage they replaced the back 2 sensors like I asked but they said they couldn't do the front driver side cause it wasn't sitting right because it was missing a "backing plate" so I paid for what they did do came home slid the sensor right in the hole and no more lights (for now)
