I have an 01 is300 auto with 58k on it. Its my first lexus and therefore i have no idea if this is pretty common or not for these cars. The "check engine" light came on not too long ago and then turned off the next day. Just last night it did the same thing, came on at night and turned off by morning. I took it to autozone to get a reading on it and the receipt said "the PCM has determined that a malfunction exists in the heater circuit for oxygen sensor 2 in bank 2." Im assuming i just need to get that oxygen sensor replaced and it should be fine? Like I said, im pretty new to these cars so any help would be appreciated. thanks

yeah i think your o2 sensor has gone bad and needs to be replaced
