O2 sensor on 06 explorer
CEL came on and showed P2195 o2 sensor upstream running lean. Ive also noticed that when the truck is cold, there is a pretty noticeable whistling sound coming from the engine bay. Could there be a leak somewhere that is also throwing off this code? Taking it to my mechanic on Tuesday but would love others opinions as well. Thanks.
