On my 2004 Volkswagen Jetta 1.8L, how do I fix the code P0030? Causing misfire
HI there
This code means there is a problem with the heater element in the bank 1 front O2 sensor. This is the sensor BEFORE the catalytic converter. This doesn't typically cause a misfire. If you have a misfire I would look for other possible reasons. Here is some more info on the code for you.
