A P0147 is caused by a failure in the O2 sensor heater circuit. The heater circuit is used to allow a more accurate reading (for O2 sensor) while system is below normal operating temperature. The only way to properly fix this problem is to replace the O2 sensor, however you can clear the code and it may be a few days before it comes back [and sets check engine light]. This condition is somewhat common on GM vehicles of that age.

Even a loose fuel cap or distributor cap can bring up the light . Without codes it will be like shooting in the dark to identify why it is light up. Any fault , anywhere in the car can cause the engine light to come on.
Unless you face any problem in your car dont break your mind over that.
