as in title
heated 02 sensor, screw in type (not flanged). doesnt matter what plug is on it really.
i will say 'to suit toyota' but i think theyre pretty interchangable.
new or used - just need to get one in and working - i need to fiddle...
cheers

sorry to hijack the post. whats the go with the heated type? I have a single wire one (non heated obviously) on an MT-4 ecu and it's terribly inacurate and i'm sure it's because it gets too cold (have extractors) can I get a heated type (I assume all multi wired ones) and use that? do they just have one signal wire, and a +ve and -ve for the heater element? Any dangers/problems with using one and does anyone have one left

hey glenn,
turns out mt AFR meter was drawing a load and thus making it look like the 02 sensor wasnt working. all fixed now, thanks 
as for willwal: youre pretty close to the money with what youve suggested. if a single wire is too far away from the head, it may not get hot enough to operate properly (minimum 550degC)
3 wire is:
+ve heater
-ve heater
signal
4 wire is:
+ve heater
-ve heater
signal
signal ground (rather than just earthing the signal wire through the body of the sensor, it has a dedicated wire to earth back at the ecu)

Ed's on the money there. dangers? you have another power wires running around?
they last for a long time. the Bosch ones i have are meant to last for 100,000km (according to Bosch, assuming ideal conditions or something)
i have a couple each of both Bosch and NTK 4 wire heated sensors. they have 18x1.5 thread (standard type)
they are $63 including postage, $60 for pickup.
pm me and i'll link ya to a pic of them.
Cya, Stewart
