Rear wheel speed sensor problems
Good day, everyone!
My wife's '05 Sienna LE, FWD started having some problems a few weeks ago after running over something in the road. The Brake and ABS lights were on solid, the tire pressure light was flashing. I took the van to a Ford dealer where my brother works and he hooked up their Snap On scan tool. The right rear wheel speed sensors was dead, no signal at all.
Since the van has over 210K miles on it, I decided to replace the entire bearing hub assembly, rather than just the sensor. It was rusted in there pretty good, but I did finally get the old one out. Afterwards, the lights were still on for a while, ~10 miles or so, then they went off briefly, then they were back on again. Do I need to have the codes cleared, or will they eventually clear after driving a while longer?
I inspected the speed sensor harness from the sensor back up to where it goes thru a grommet and into the inside of the van. I did not see any obvious signs of damage. Is the harness serviceable where I can just replace it? Is there a connector inside the van and if so, how do I access it? Thanks and have a good day!
