what kind of speed sensors? the abs sensors that go on each wheel, or the rear and front speed sensors, that are located on the tod it self on the rear sise of the tod, 1 on the top part and the other on the bottom? have you cheack the tod computer? eather u could have a loose wire, or a broken connector, or upluged. or you might have need a new tod computer, it might be that its fried and u need to replace it? or a fuse of your TOD? the tod computer is under the passenger side seat the american version, but i would think the tod should be under the driver for you, i don't think they would move it somewhere else. cheak and see if its under the driver fist and if not under the passenger. Have you taken it to get the code, to see whats really wrong? If you get it cheaked they will tell you whats the code the Vehicakl is throughing to indacate wahts wrong. or I can say 1 more thing. probley everything is working good, just probely when you had your VX fixed before, they connecting things wrong. OH and also 1 more thing, never try to clean the sensors your self. if they are new to try cleaning them, cuz that can mess up the sensor its self. just try it with not cleaning it. Hope i could help, i have the same problem, but mine is the rear speed sensor, that is located on the Tod itself.
