Thank you guys for the help, I'm still a bit lost; I can't figure out which sensor I need to change, the code is asking me to change 'bank 2 sensor 2' which I assumed was the one on the bottom (because this started while I was driving through a storm and hit a big puddle of water). Do you know which one that might be? and if possible could you give me a part#? I appreciate all your help. Ralph

The code I got was P0057 'HO25 Bank 2 Sen 2 Heater Circuit Low' my understanding is this is the O2 Sensor at the bottom of the exhaust. My next question is, when I went to pick up an O2 sensor there were to types OE Bosh (not in stock) and Universal Bosh (in stock and cheaper); is there a mechanical difference or are they basically the same other than the fact I have the splice the wire?

Can some one help me? I have a 2003 IS300 (manual) and yesterday I was driving through a thunderstorm and at some point I think after hitting a puddle my CEL came on and the 'Trac Off' light began flashing. I tried to disconnect the battery and reconnect but that only work for about 10 mins then the CEL came back on and the trac light was flashing again. I have not done any mods to the car (yet); It's stock, and it has about 40,000 on it. What is causing this and how can I fix it? Thanks
