How to Reset the Service Engine Soon Light on My 1997 Monte Carlo

If the "Service Engine Soon" light comes on inside the dashboard of your 1997 Monte Carlo, you can turn it off by disconnecting the battery. Service engine lights can come on inside of a car if you have recently changed an oxygen sensor in your fuel tank, for example. Dealerships and mechanics might tell you to drive the car for about 20 miles to clear the service engine light, but there is another way.

Instructions

1

Turn the car off. Pop the hood to your 1997 Monte Carlo, and locate the battery.

2

Disconnect the red terminal from the battery with a socket wrench. Disconnect the black terminal from the battery with a socket wrench.

3

Go to the ignition switch inside your Monte Carlo, and put your key inside. Turn the ignition switch three times. Turn the ignition switch to "OFF", and then reconnect the battery to the terminals.

4

Turn the ignition switch to "ON" without starting the Monte Carlo. Leave the ignition switch on for one minute.

5

Start the car and the "Service Engine Soon" light will be off.
