Heated oxygen sensor
Hello all a quick question,
I have an L Reg 94 model and wanted to get 2 new HO2 sensors LH and RH and wanted to know if there a 3 wire or 4 wire can anyone help? Oh and I have a haynes manual for an MX6 are they in the same place so I can use this book?
go onto fordprobestore.co.uk and email the owner (Mark) stating all your relevant car spec, he'll sort you out :)
Yea same approximate place I'd imagine. Slightly different headers of course. They're pretty obvious though, they stick out about 2.5"s out of the exhaust manifolds.
get the mx3 manual in general section.
done that but couldn't find the section on Heated Oxygen Sensors :shock:
Dont want to sound like a plum but have you looked under the car at the looms that plug onto the sensors and counted how many wires there are?
Took the one at the front out and its a 4 wire. I have got the sensors from the probe store but have to crimp to the old plug. The problem is that they are different colours. 2 blacks a blue and a white on the original and 2 whites a gray and a black on the new. I have what the wires are for on the new sensor as it came in the box but don’t know what the wires on the old are, can any one help?
