'99 UZJ100 w/ 80000+ miles
I posted awhile back about O2 sensors going bad and CEL kept coming back with the same code (0155). This time I brought the 100 to a refutable independent service and had the whole thing checked. It turned out the front sensors were bad too! So, I got them replaced. Cost $138/ea plus $150 labor. So, the shop owner told me that using gas additives (to purge carbon deposits, etc) and cheap gas (Costco) just kills the O2 sensors. And driving with the CEL on can ruin the catalytic converter. So, all you folks out there putting a black tape over the light, and/or ignoring the CEL, it's pay now or pay (much more) later. There, my 2 cents. Thank you
