http://engine-codes.com/p0030.htmlHi,
I have a 2003 Subaru Legacy, I replaced the Oxygen sensor and the code is still there. I checked the wiring and the voltage is there for the heater bank. I believe this to be the upstream before the Cat 02 sensor air/fuel. Any help appreciated.
Moved to Bizarro? That's Bizarro. This is a real problem.
