I paid 180 from Ford its brand new only coverd .3 of a mile so make me an offer its in the original packaging ready to goWell, I thought I'd try the unplugging method. EML came back on 3 days after resetting. Still showing the same codes. I reset the codes, and they started showing straight away on the reader. Reset them again, unplugged the front lambda, and scanned it again. This time no codes showing live. Plugged the lambda back in, and this time no codes shown.
