I recently imported a used Toyota Corolla Fielder 2007 model. However, the "check engine" light could come on as you drive. Sometimes, the car just revs on its own; like its engaging a lower gear. I took it for computerized diagnosis and the report indicated that the vehicle speed sensor had a problem and that the output speed sensor circuit had no signal. What could be the best way to handle this? What needs to be replaced; if at all; and how much is that likely to cost?
