I replaced the bank 2 sensor because the shop that installed a new clutch, etc. pinched the wire and it was measuring 5.8 ohms. I figured that it was sending a low signal back to the PCM which was richening the fuel mixture then causing the PO172 code. So while I was under the car one day I decided to switch the two.
The freeze frame I have is:
RPM 2713
CALC Load % 12.2
Coolant temp. 183
LT FTRM 1 % -24.2
ST FTRM 1 % -6.3
LT FTRM 2 % -18.8
ST FTRM 2 % -7.0
Veh. speed 45
Fuel sys 1 CLSD
Fuel sys 2 N/A
I don't have a clue what all this means.
