16825 - EVAP Emission Control Sys: Incorrect Flow
P0441 - 35-00 - -
17521 - Oxygen (Lambda) Sensor: B1 S1: Internal Resistance too High
P1113 - 35-10 - - - Intermittent
Readiness: 0000 0000

I changed out the driver side primary and secondary... and passenger side secondary O2 sensors with Bosch sensors. Still getting that 17521 code. Help.

Also, I have parktronic on my 2002 4.2, but when i try to read channel 76, it says that it cannot read the computer. Do i have a loose connection somewhere? maybe a fuse?
can anyone help?

Thanks!

or will only the 16825 code give me a CEL.

The stupid yellow light is killing me!

I know it seems screwy, but bank 1 is the right bank in every car I've ever worked on, other than an 01 Toyota Land Cruiser. Replace that sensor also, and you should be fine.

Still looks like you need to do some diag work on the EVAP problem as well.

I was told it was the driver side - Did replace a good sensor?

unless you're working on an '01 Landcruiser. Seems as though Toyota did their best to **** me off on that one.

so pissed off after replacing (what I thought was) B1S1 on this Landcruiser, and having the light come on during the second drive cycle with the same code.
