Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** you have a check engine light with no codes then either the code reader is not compatible with this vehicle or there is a problem with the computer. Most of the time if you have a check engine light with an erratic speedometer it is caused by a bad speed sensor. This commonly occurs on this vehicle. If you have access to another scan tool see if it will read the codes. If not then you may have a computer problem.
