INPA code 2CA9 / P0161 - lambda sensor

[rjhl64]

Is the code for the pre or post set of lambda sensors. Any pointers would be appreciated.

01/11/22 - reset the EML on Sunday afternoon, no issues so far, but i do believe the lifetime of the lambda sensors is about 250,000 Km, the car has done over that ~272,500 Km, so im guessing i will need to replace the two pre-cat, or play around with INPA to get better understanding of where the issue lies.

You certainly dont want the post cat sensors as one of them has been unavailable in UK for some time. But sorry I cannot translate that. I have to reset my EML periodically as my lambda sensor is the unavailable Bosch sensor. Strangely the light only comes on when using E5 fuel and not when I splash out on E10.
Might be worth changing your fuel if for instance you are using supermarket E10

Sorry got that wrong way round E10 is the newer fuel, and my car seems ok on E5

Using google translator it seems that your after cat sensor bank 2 heater is not working.

Light came back last night on the way home from work, had another look at the error (more detail - Code P0161). I will try the suggested method of improved quality fuel (Mike6 suggestion), failing that i will need to source a replacement lambda sensor.

update - as per the suggestion from Mike6, i ran the car over the weekend and covered ~160 miles+ (2 x 25 liters of super unleaded) and no light, so it seems my car doesn't like E10. Any changes and i will update, so far so good.

update - no EML lights so far, but will load up fire up the laptop to see if there are any errors.
