Air fuel ratio sensor location
I have an "00 3.4L Runner (Canadian spec - single cat) and am cosidering buying URD's Air fuel ratio calibrator. Not sure if this will work on my truck though. The truck has two O2 sensors and looking in the factory manual it most likely has an air fuel ratio sensor but the manual does not show where it is located. URD has not been able to clearly tell me whether their new calibrator will work on my truck.
Btw, the truck is S/C'd with 305 cc injectors, Walbro fuel pump, SAFCII etc and I am just trying to get my AFR's adjusted while in closed loop and this device looks like it is just what I need.
Can anyone help ID the location?
Thanks

Your truck is listed on this page:

I don't think Canadian spec makes any difference. Look on the exhaust downpipe right after the crossover joins and the first sensor you come to is the AF sensor.
