Reseting the On-Board Diagnostics System (Cars Computer)
My car was operating perfectly until I disconnected a connector near the oil flter (believe the wire to the connector comes from the manifold) so that I could replace the oil filter. I drove with the wire off for over 50 miles and the Check Engine Light came on. My Question is: Can I reset the On-Board-Diagnostics System (Computer) to distinguish the Check Engine Light, assuming there is no other problem. Also, what must I do to reset this System (computer) and will it harm or cause other problems with the car. Also, when I reset the system what must I do to return the car to normal.
If you reconnected the connector, the system will reset itself given about 100-150 miles of driving with the connector in place and working. You can get Advance Auto parts to reset your computer for free, or you can have it done at a dealership. It should cause no other problems, however, if the problem was NOT your disconnected connector, the light will come back on if the root cause is not fixed.
