Is this blown code important?
Haven't seen a CEL for a couple of years but my Z just blew a 0030 or a "heater control circuit" code. Went to erase but the CEL stayed on. (maybe I didn't wait long enough). Is this code important and do I need a trip to the dealer? Thanx...

P0030 is "HO2S Heater control circuit bank 1, sensor 1.
Drivers side upstream O2 sensor is reporting wrong data to the ECM.
You've tried the battery diconnect/reconnect? Thereare 3 pages of sequential tests for the Dealer to perform to check this code. One of the tests is "Check the fuse that supplies the applicable HO2S sensor".
