4AGZE O2 sensor

[sleepyfellow]

hi all,


how many o2 sensors are there on the 4AGZE. I've seen pics that there is one at the exhaust manifold. On my car, I can see one close or maybe on the cat but none on the manifold. Is there supposed to be one there?

Damn. Thanks dude. That might explain my high fuel consumption in heavy traffic. Anybody know where the o2 sensor wires connect from? It would be great if someone out there has pics.

cheers

very easy... look at your extractor & search all along it until
the mid box if u have to. Found a wire coming out of anywhere?
If yes, follow that wire... where it connects to? Your wiring loom
in engine bay... right? ....oh, but u cant find any wire coming out
from your exhaust... darn... are u in trouble? yes u are.. because
on close loop/ non WOT (wide open throttle) calculations, your
ecu uses the o2 sensor to tweak the riching or leaning of your
fuel... Heavy Traffic = close loop, non WOT.... trouble? yes
u are... very deep.... MUAAHAHAHAHA... O2 O2 O2.... MUAHAHAHAHA
.... O2 O2 O2... MUAHAHAHAAA.. blardi lan pepet....
