I have a 95 4runner California version v6 with 143K miles. I got the famous code 25 and it is driving me crazy. I checked the resistance values of O2 sensors per (Toyota 4runner manual)front of catalytic is 5.6 ohms and rear of catalytic is 16.2 ohms. are these reading within normal range? can anyone verify this for me? i hate buying O2 sensors if i don't have to. any other tips will be greatly appreciated.
Please advise.
