How do you reset the check engine light on a 1994 Chevy Beretta?

Answer 1

The check engine light indicates a problem with the emissions system so to permanently clear the code you must have the codes read and correct the problem, it is most likely a faulty sensor. Auto parts stores at least the big chains can read the codes for you and also help in clearing them when you are done, however you can disconnect the neg battery cable to reset the computer but be careful GM radios will go into security lock when power is interrupted and need to be unlocked at a dealer. If you are trying to get a smog certicicate on the vehicle and it wont pass due to the check engine light simply resetting it wont help because you will have to log around 100 miles before the smog computer will test it again and by then the light will be back on.
