I'm new to this forum, and i'm looking for a little help.
I have a 2004 Legacy, with cal emission (EJ259 engine code I think), bought it in Maine. The car has 3 cats and 5 O2 sensors. Today, the "check engine" light came on, I got the code, P0043, I checked in my manual, MY2005, and it doesn't list this code? I googled it and it seems to be " heater control circuit low, bank 1 sensor 3" Anyway looking for the Subaru diagnostic test procedure for this code, This is the step by step follow through that shows you to check all points in the system to eliminate things that could also cause this code to be set. If someone knows where I can find it, that would be great. Thanks in advance, I'll check back tomorrow.
