WTF? I never had this one in 23 years on the old car.
Now with the new car witrh less than 40K miles this keep coming up.
As read with Launch scanner
G3/2(O2 Sensor Upstream of KAT) : Sensor Signal in Case of interia Fuel Shutoff IMPLAUSIBLE (P0130)|
Also there's a drop down that says P2031-032.


Huh? Has anyone had this error on their W203 and what was the fix? I've read all the generic stuff online.
The car is getting great mileage and runs fine.
This is a new one on me. Had a weak 02 sensor on the other car once. it never has this error.
So like I said, Has anyone else had this error on their W203 ?

 

And just like that the EDIT button is GONE! I wanted to add that this car has NO corrosion, appears to have always been stored in garage
in NorCal car it's whole like so like I said no corrosion. It's a 'joy' to be underneath how clean it is or at least was when
I bought it a few months back( if ever being under a 1.5 ton+ car can be called 'joyful' NOT!)
