This is not true - the P/O also told me that it was the right front ABS speed sensor that was causing the issues (solid light ABS on all the time). I installed new speed sensor but there was no change in the dash light.
Then I found a a thread here that mentioned shorting certain pins on the OBDII port to actually visualize the ABS codes (which can't be read by the rental OBDII scanner at the local autoparts store). After following the directions on the thread the code that flashed on the dash (the ABS light flashes a certain number of times) indicated that the module was dead.
If you're ABS is solid on, you're module is the most likely cause.
If someone has a spare broken module lying around, I would love to dremel into the casing and see if there are some broken caps or resistors. It is known to begin functioning in very cold weather, only to stop once warm.
If the module can be rebuilt for 100, the issue should also be fixable by an amateur at home. If anyone has a spare, let me know.
