Hi guys, I realise this topic has probably been done to death but I've been searching extensively and can't seem to find any conclusive answers.
I'm brand new to Subaru, I've just picked up an 09 Liberty Sport Edition (2.5) Gen 4 and whilst driving down the highway I momentarily flashed my high beams and instantly the traction control light and engine light came on solid and cruise control light started flashing.
I pulled the codes up and got P0420, C0042 and C0071. I tried resetting the codes by disconnecting the battery for half an hour but it all remains.
Are there any recommendations of what I can look at to remedy this issue? The car is still driving absolutely fine, you wouldn't know anything is wrong with it.
I've seen a bunch of threads regarding the P0420 codes relating to O2 sensors and disabling it in the tune, but very little regarding the other two codes.
Any help would be much appreciated. Cheers!
