Different O2 Sensors Front To Back Of Turbo B Series?

Just replaced my o2 sensors on the ute & noticed the one behind the cat had a blue connector on the loom & the other at the turbo had a green one. The plugs were basically the same save for the indexing tabs on the sensors themselves. I snapped the tabs off the sensor & just plugged it in to the loom. My understanding is that o2 sensors are pretty much to a standard & they should work when plugged in. So far, no warnings/limp, economy seems better, power is good.

Anyone know if there is a difference? (couldn't imagine they would use two different sensors like that surely? I'll ask a former FPV sparky I work with tomorrow as well)

I looked into this some time ago. It seems on the surface that there is little difference however why would they be a different colour and indexed differently. I am currently running a blue on the front green, however now that you mention it, it does not seem to always go into closed loop at idle so I think I need to look into again.

I disconnect the rear sensor via HP Tuners as do most tuners to avoid error codes.

I have a blue connector sensor that I got with a cat I had. I have a BA xr6t which has one green sensor only (no blue). ford told me the blue ones are 250 new and green 140

if your after a blue one I have one for $40 works perfect as it did on the donor car

Probably keep that in mind actually mate. Ute's starting to drink a bit of fuel which I wasn't expecting, trying to figure out what's going on. Could be likely that rear sensor

Well, just did a long distance drive & got 8.7L/100k. So not real sure whats going on. Thought is at this stage the temp probe in the rear is a little more sensitive & effects the tune in town situations

Replaced both my O2 sensors with green VDO ones off eBay, pulled the little locating lugs off with a pair of pliers, whacked em in.

2 weeks later no issues, improved fuel consumption and runs smoother. I'd give it the go ahead.

My old ones were stuffed btw (5.0L/hr at idle) so they had to be replaced and the eBay ones seemed legit enough.
