Thats not the code. The code should start with a P.
Most likely causes are MAF or broken Lambda
Hi,
Thank you for your answer. Code is p0420.
Can leak exhaust cause also this?
Also my second Lambda seems damaged outside but obdii shows voltage change

Update:
There was a leak at exhaust. We fixed it with pasta and metal clamp.
Now the second sensor is stable. After that we have cleared the Fault by OBDII adaptor. It is gone since 2 days!
Lets see if it will come back
