ABS sensor issue.

I have traction control light on, BRAKE light on, ABS light on with the VSC light blinking. And my driver rear passenger caliper brake pads wears out quicker than the other 3 calipers. Does that show me that the sensor on the driver rear passenger is bad? This is 2nd time I replaced these pads. And they only last 2 months. Need help. And if it is the ABS or speed-sensor where do you guys recomend to get the sensors? Will RockAuto.com carries the right sensor that will work for this matters? I don’t want to go to the dealer for these parts because they are big time rip off. Thanks for all suggestion.

 

If you are handy with a computer and own a laptop I would download Toyota's TechStream software. With it and a cable you can get off of ebay for around $25 you can connect up to your Tundra and it will tell you what the computer is seeing. Otherwise you will have to pay someone to do the same. Most of the cheap OBD devices can't read subsystems so they may not tell you what's going on. But you need to find out what the computer is trying to tell you before you just replace parts.

On my 2000 Tundra the right front abs sensor had a problem. Using a multi meter I was able to test it and found out the sensor was fine. It turns out a small stick somehow damaged the wire going to the sensor. Since it only has anti-lock brakes the computer didn't think the wheel was slipping so it wasn't trying to apply the brakes.

 

Wheel bearings going bad have been known to cause ABS sensor issues.

If the pads are wearing quicker, could have a caliper issue....which also would cause the brakes to run hotter.....which could cause the hub to get hot and the bearing to fail quicker.

IMO there are still some diagnostics and other things to look at before throwing a new wheel speed sensor on, such as the obvious - brakes.

 

At first I thought it was the caliper but if it is the caliper than when I push back the piston, it should be seized up. But no the piston is freely push back from the last time I replace my pads. About the wheel bearing, I have no wable when driving to. Yes my wheels runs hotter because it seems like it’s been pressing on the rotors the whole time I’m driving it. I don’t know anymore. But thanks for the idea. I appreciate it bro.

 

Get those codes read first, go from there.
