So my car through 3 codes last night once I started it up. And that through them again this morning when I started it up. I clear them and the salt light on the dash goes away one of the Cubs seems to still be there. PO141 O2 heater circuit bank 1 sensor 2. I don't recall the numbers of the older two codes but they were pertaining to heater resistance they're basically all three were the 02 sensor heater. my question is is this normal sometimes with a combination of the cold weather and defouler. I left the rear O2 sensor active on my stage 3 tune. Does it sound like I just need a new O2 sensor.
