'02 Volkswagen Beetle 2.0L

sensors

#1

The car has an O2 sensor code. The car also won’t rev past 3000 rpm. Is the O2 sensor code related. The sensor before the cat, heater circuit failure.


#2

Posting the actural code would be helpful It should be in the form (P0123)

I am not sure what you mean “The sensor before the cat, heater circuit failure.” Do you mean it is a code for a bad sensor reading from the first sensor?

How is everything else and how long has this been a problem?
