PO141 Sensor Heater Circuit Malfunction Bank (1) Sensor (2)

Hey all,

I have a '00 CLK 430 and have had my Check Engine light on. It's been fluctuating on and off lately. I had my mechanic run a diagnostic and the error message was "PO141 Sensor Heater Circuit Malfunction Bank (1) Sensor (2)"

I'm wondering if this is something I can do myself, and what part(s) I would need. Any information would be extremely helpful.

Thanks!

Figured out that Bank (1) Sensor (2) means Passenger Side Rear sensor. Bosch Part Number 15092 (dealer charges $290; Amazon has it for $<90 - gotta love online shopping!)

I'm guessing I might be able to replace it myself. Any advice or DIY instructions would be appreciated!
