I took it to AAMCO for a free diagnosis and they told me this

p0131 o2 ckt. low voltage (b1s1)
p0137 02 ckt. low voltage (b1s1)

Just to mention as well i recently had a transmission oil leak through the electronic connector( ive seen it on the forum as a common problem) I recently got that fixed and was wondering if maybe the oil that was dripping could have damaged these two sensors? Because i really doubt they both went bad at the same time.
