The day before I got this obd code I changed clutch and gear box oil. 15 minutes before I got this code one of my brakes pads completely wore out. I read a bit about the code and I guess they are not related but I am still learning so please let me know if they could be related.
As for the code, other than for the environment, is it something serious or something I need to worry about, can I just clear and continue to drive? I plan to sell after a 1-3 months so if nobody notices should be ok.
I suppose if I get some symptoms such as low gas mileage, misfiring or loss of power, only then should I do something?
Is this an easy diy repair, what is the difficulty of diagnosing and fixing this task, might i be better off going to a mechanic?
Can you give me some directions or are there any resources to show me how to diagnose the problem so I know what needs to be done.
