Hopefully someone can offer some advice to help me out. Vehicle is a 2006 Toyota Sienna AWD. The Brake, ABS, VSC and Low Tire Pressure lights came on after I noted some ABS activation when pulling away from a stop. I researched this and came to the conclusion that I have an ABS problem. I removed the two front ABS sensors, cleaned them up, Checked the tone rings, checked for sensor resistance (roughly 1,000 ohms each), checked for system voltage at the connector (roughly 4 volts on both sides), and reinstalled. Then I attempted the same procedure on the rears. I removed the ABS sensor bolt and bracket, but the sensor was stuck tight. This vehicle has 240,000 miles in the salty northeast, so corrosion is always an issue during repairs. I tried tapping, twisting, prying, etc. Evenutally I wedged a thin screwdriver under the ABS base, but I broke off the sensor. The base of the sensor is still in the mounting hole. I have applied liberal amounts of PB Blaster to this side and the other side and I am letting it sit overnight. Probably should have done this BEFORE breaking off the sensor. Does anyone have any advice fro getting the remaining part of the ABS sensor out of the mounting hole? There is a short metal core that I was thinking of grabbing tightly with a Vice Grips and twisting while prying up. Also, any advice for keeping me from breaking off the other side? Finally, is anyone familiar with where the sensor plugs into the vehicle wiring harness after it enters the vehicle body in the wheel well? I looked for a two wire connector under interior panels in multiple places without luck. The front sensors were easy because I could simply follow the wire under the wheel well liner with my hand and unplug. The rear connector has me stumped right now. Thanks in advance.
