It has a diagnostic code of DTC PO141 Oxygen sensor heater circuit bank 1 sensor 2.I had already replaced the oxygen sensor I buy from Toyota.I reset the engine check by disconnecting the negative battery terminal but when i run the engine check engine light on again.What other things i need to check to clear the check engine light.Is there a fuse or relay connected to Oxygen sensor heater circuit?
