O2 sensor, what type do i need?

[danny_ke70]

Hey guys quick question, i have a 4agze in a ke70 and im trying to find out what o2 sensor to run. All i could find in the forums was a four wire o2 sensor. Is this all i need to say? whats the difference between two wire and four?

Cheers

4 wires are heated. 2 wires are normal, toyota use single wires and they ground out thru the body/exhaust/headers/ground strap.

if you dont have a fitting for your o2 sensor you can get whatever you want. otherwise get what you can fit on/in the fitting. Only 20v's had 4 wire o2's

you should get a 4 wire sensor as this is what 4AGZE'S used.

single wire it is!!! thanks for the reply

Forget i said anything, my 4agze bigport shitty aw11 only had a single wire.

But seriously, it an 02, it will heat up eventually.

oh true, no worries 4 wire it is then. Thanks for the reply!!!

Yeah thats sort of true biggo. Depends on location. If you put a one-wire where a four-wire is meant to go, it will never get to temp...
