LAMBDA Sensor Bank 2 error

[D0nni]

Hi,

Just hopefully a quick few question. I've a Lambda sensor error "61 Activate Lambda Probe Heating after KAT Bank 2"

1) Will replacing the Lambda sensor resolve this issue?
2) Which part number is the Lambda Sensor for the Bank 2? (11781742051 or 11781739845)

TIA

Looks to me its number 5 for post cat bank 2, difference being the cable length between 1 and 2 sensors. Probably the heater circuit in the sensor has given up.
