2002 ABS Wheel speed sensor location and replacement
3 Attachment(s)
trying to help family by keeping this 4runner with 300K miles in service.
ABS error , the right front and rear sensor on the wheel show zero in Techstream when I drive here is the snap shot of data from techstream below found them both shipped from aliexpress for under 40$ the question is how involved is replacing them? could it be just dirty? how do you clean them? the problem came about after changing tires .. so the tire shop did something I have to check but a quick pick I don't see any major issues is it normal for these 2 sensors to read zero?

The wheel speed sensors are pretty easy to replace. 1 bolt holds each of them in then take a pair of slip joint pliers and twist/pull the sensors out. When you take the rear wheel speed sensor out spin the wheel if you can and look at the tone ring. If there is any oil on the tone ring then it's time to do rear axle seals and possibly rear wheel bearings.
I have no experience with those sensors. Sorry |

I can get it done by going under the car while the car on a ramp, no need for full on lift? |

I'm not entirely sure about the front wheel speed sensor. You may need to remove the wheel and possibly the rotor to get to the wheel speed sensor bolt and clearance to pull it out. |
