nope,i dont think this is a speed sensor, i get this code alert "service stability system"
i got my car to the dealer and its a sensor behind steering wheel, (steering wheel positioning sensor) the sensor that detect the position of the steering,
and when alert come on, the electronic steering system is disabled.
the sensor is 78$ canadian + 1 hour labour.
hope this help
and for the speed sensor(in wheels) its the "ABS" light that will come on..
i know it because it happen to me
(note..: the steering will still run good, its just the electronic thing disabled, i run with mine
disabled like 6 month)
i got practically all available problem relative to bonnie on my car.
BUT.. i still love her, she never feel that good.. now! (everything repaired)
