Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. When a check engine light is on it must be reset after the repair is made. The light will not turn off on its own. If you replaced the sensor and the light was not reset then a computer scan tool must be used to reset the computer. If it was reset and the light came back on then there is another problem. Did they happen to give you the code number?
