In October 2014 my car threw a code P0125 and later at Toyota also threw P1135. They diagnosed a faulty A/F sensor B1S1 and charged me $400 to diagnose and replace.

I have noticed when a sensor fails on one bank, they are likely wearing out and the other may follow. That's what happened with my VVT's a couple of years ago.

Got a check engine this week and it came up P0125, P1155, P1153P and P1155P. I don't know what the "P" is after the code but do you all agree this is a faulty A/F sensor B2S1?

And if so, Amazon is selling what appears to be OEM for $98 and I can have a local indy install it - a DYI is impossible as I'm severely mechanically impaired.

Any advice would be greatly appreciated and also let me know what you think what labor charge would be fair just to install. Thank you.

The P means pending.

And, yes I agree it's time to replace the A/F sensor on B2 S1. You can reset the code once if you want and see if it returns to confirm. The amazon part is correct!

Here's my personal experience with when sensors die, two of them decided to die almost together on my RX.
Bank 1 Sensor Sensor 1 died at 215,000 miles about one month ago.
Bank 1 Sensor Sensor 2 died at 158,700 miles.
Bank 2 Sensor 1 died at 150,000 miles.
