    I had a check engine light and i got a p0141 code. I tried searching online to figure out what sensor i need to buy and i got a bunch of different answers. This is the first car i have ever owned that had o2 sensors so any help as to what sensor this is and where i could buy it online would be greatly appreciated Thanks

    A code P0141 may mean that one or more of the following has happened:
    open or short to ground in the wiring harness
    O2 heater circuit wiring high resistance
    O2 heater element resistance is high
    Internal short or open in the heater element


    Long story short I would check the wiring from the wire harness the the plug that connects the O2 sensor, if it is good buy a new upstream O2 sensor.
