'07 ES350, 70,300miles

I replaced bank 2 sensor 2 with a Denso part, will the check engine light turn off by itself or do I need to clear the codes myself?

Which fuses do I check as part of the troubleshooting for P0057?

think the answers are here, efi fuse, clear dtc and check for recurrence

Thank you very much, this is the first time I have seen this document. Every time I did a search, the only solution I could find was to replace the sensor. I'll go to Autozone to see if they can clear the code for me and I will work with the document from there.

this gives you the prob causes of the P0057 dtc also

Autozone and O'Reilly won't clear my check engine light with any of their scanners. It's CA law now that only ASE certified mechanics can clear check engine lights.

Can I just disconnect the negative battery cable to clear the check engine light on the '07 ES350? Or will that screw up the computer?

Looks like I don't have to disconnect the battery. The check engine light went out by itself after not driving it for a week. I drove about 20-miles and the check engine light did not come on.

I replaced my bank 2 sensor 2 with a aftermarket part. Denso 234-4260

Codes typically clear themselves once the problem causing them has been fixed. It usually takes a bit of time/mileage for the ECU to confirm the problem is no longer occurring though.

You can also get yourself a cheap scanner from ebay. Most of them have the ability to clear codes.

i got the Oxgord code reader for $15 on Walmart.com. Pretty sure it's how the Chinese government is spying on me... anyway, i tried clearing the code but it errors out. No worries though, the light went off after replacing with the above mentioned Denso part.

when taking the old part out, it's a good idea to find a 6 point 7/8" flange wrench... as long as you can find. A closed end 7/8" 12pt works ok (that's what I used. Don't bother with the o2 socket they sell at the parts store.

Or from Autozone; they won't clear the code for you, but they'll sell you one to do so. I bought my first OBDII reader from them when it was on sale for $20. Still have it, but have a fancier one for most readings.
