Question about 2003 Nissan Sentra
Disconnecting the battery might reset the check engine light on your car.
However, keep in mind the following:
- not all cars will clear the code after disconnecting the battery
- some problems, if not repaired in time may cause a serious damage and more costly repair.
- the radio, if code-protected, may be locked after disconnecting the battery
- the "check engine" light will come back anyway if the problem still exists.
But by all means try disconnecting the battery (for at least 1 minute) first.
