2004 Taco Rear speed Sensor Prb - Need help

Hi Everyone,

I hope you're all doing well. I'm reaching out for some technical advice regarding an issue I've been experiencing with my ABS system.

I'm using Techstream to diagnose a persistent ABS light on my vehicle. I've noticed that the rear right passenger ABS speed sensor doesn't register any speed below 16 mph. It only starts reading at 16 mph and above, whereas all the other sensors begin registering from 1 mph upwards.

I've already tested the speed sensor and its wiring, both of which seem fine. I even replaced the sensor with a new aftermarket one, but the issue persists.

At this point, I'm unsure what else to check or try. Do you have any suggestions or insights on what might be causing this problem?

Thank you in advance for your help!

Best regards,

BTW wish everyone Happy Holidays!

 

Have you checked the tone ring for any debris? should be able to pop the sensor out, and spin the axle shaft to check down the sensor hole.
