I live in WV, so I guess the replacement Denso O2 sensor should work fine. I might do both of them since they're $79 each. Can these sensors be tested by using an DMM with the car running? I wasn't sure if the harness could be unplugged and a meter used to check for fluctuating voltage readings...

Thanks for the link for new O2 sensors. That's the best price that I've seen. Has anyone else got the same code when the O2 sensor goes out? I'm sort of confused as to why the other codes are showing up. ' Just wanted to make sure something else isn't wrong with it. Thanks, Dave

Thanks for the code lists, guys. I think it needs a new O2 sensor, but am unsure of which one. Also, I don't understand why it would be giving a coolant temp sensor and pedal position sensor code. Thanks, Dave

The CEL on my '99 4Runner 3.4 L 5 speed came on the other day. I read the codes with my OBD II reader. They are: P0125, P1135, P1133,P1135. I couldn't find a listing of these to describe what they mean. I was hoping that someone on here could help. Thanks in advance. Dave
