I went down to Oreillys and checked this cars codes. It stored a code po141 oxygen senser heater, I cleared codes and it went about a week to two weeks before light came back on. Any help would be appreciated. Thanks Jerry

Hello and thanks for donating

This is a common trouble code and normally is caused by a failed oxygen sensor, however you will want to inspect the wiring to the sensor first before replacing the sensor itself.
