Hey guys,

P0030 H02S Heater Control Circuit

Possible cause of fault

- Open circuit

P0134 02 Sensor Circuit No Activity Detected

Possible cause of fault

- Short circuit in oxygen sensor wiring

- Oxygen sensor faulty (heater coupling or heating)

- DME control module faulty

You could erase the faults and see if they come back.

Thanks for the response! It's a 2002 and because of the low miles i did erase the faults thinking it was a false alarm, but unfortunately it came back. Are any of these difficult fixes? I am thinking of attempting to fix myself. Thanks again. BTW i have been trying to donate but the system has not been accepting my cc. Can i send a check?
