Check engine light came on, plugged in my scan tool, found the code P0135 Heated Oxygen Sensor Heater circuit malfunction(bank 1, sensor 1). Bought a new sensor, put it in, cleared the malfunction, next day, check engine light was on again. Let it ride for a few days, it went out, a week later, came on again. It's doing this over and over, on and off. What's the prob? New sensor was bad? Circuit prob? HELP! Car has 114,000 miles and engine overhauled by Toyota dealership 10,000 miles ago under Sludge warranty program.
