I would like a narrowband lambda sensor, but with a Subaru plug. Sources except Subaru?

 

John,

The contacts in the Subaru OE plug can be released with a small screwdriver.
I un-clipped some from an MY95 and refited to an MY00 which uses a slightly different plug.

So you can wire any 3 wire sensor to them and re-insert them into the OE plug

 

BRD, TSL, Powerstation resell OE ones.

The Subaru plug would probably be expensive to source on it's own unless you can get a duff sensor and remove the wiring.

Previously I found that soldering wires to the Subaru plug was unsatisfactory - solder didn't take at all well, plug was dodgy afterwards. Think I'll just get an OE one.

 

I have a duff sensor somewhere in my garage, would that help?

 

John,

The lambda wires are heat resistant, not sure what but not copper, possible high nickel content copper or even stainless steel. This is why the universal sensor has crimps to join to plug tails.

Alternative is to use silver solder with flux and a very hot iron or small gas torch.

The standard Subaru connector has a gold plated pin for the signal wire.

Even if you silver solder a different (not gold plated) connector on then it doesn't seem to work quite as well as an OE one.

 

could you not cut the wires and then use bullet connectors as per hifi equipment??

 

All a bit dodgy for high temperature/vibration environment. Think I'll get the OEM one.

 

While i dont particularly agree, most info I get suggests that a crimped connection is superior to a soldered one.
Its very rarely in industry soldered joints are used. Any big power joints or cable terminations are all crimped.

Even in automotive, most connections are crimped.

 

Its not superior but a mechanical jojnt is beneficial where it would be subject to vibration, the lambda wires are nickel based which is why they won't solder.

fwiw the crimps used in automotive or aircraft applications are far superior to anything you could do with the kit readily available in the commercial arena. I crimp AND solder where I can.

solder joints fracture quicker than crimp joints
afaik its illegal to solder aircraft and trains
(still prefer a soldered joint meself)
is it not possible to buy these high quality cmimps from the likes of rs or farnell

I would give Job at automotive services a call , he was saying he keeps sensors in stock when I asked him last week. I think mine is on it's way out.

as I told you when you got the last one , do not solder but use heat shrink crimp connectors with my crimping pliers

 

Does anyone know if the OE sensor has a Bosch part# (or is it just a Subaru one)?

Stefan

 

T-uk we never got your crimping pliers to crimp securely though when we tried it with the J&S - it just fell apart, or am I just a muppet?

 

Are you using the correct crimping pliers and not just universal jobs?

How is the Subaru plug wired to the sensor?
