850 Petrol 1995 2,5 L 20 V Lambda sensor Regulating probe issue

Post by manovlov »

Hy Guys,

I continue to rebuild my 850. After the replacement of the exhaust line, came the time to replace the Lambda sensor Regulating probe. It was a pita to get the unique sensor out. But it finally arrived. The issue is on the other way. The security red plastic brake has been broken, and the connection between the plug 2 parts was realized with zip ties... under a tonne of black scotch (also a mess to get unglued).

How could i repair this connection. Shall i buy a used harness with the plug in good state ? Re-use the principle of zip tie (that doesn't convince me) ?

Drown the all stuff in a kind of glue ?

Find someone who would have an old harness and who could send me the part of the harness with the functional plug to receive mine (it has a little side "butcher action, no ?), or at the occasion could pick up for me this part on an unusable harness in a junkyard ?

I've searched on internet her , in France, but guys ask so much for the all harness that it looks like they count on me to pay their retire...

Thanks to those who will answer to me.

So the secondary locking device is missing from the receptacle? AMP part number in your picture is 4-965101-1, I guess if you look at the other side of the housing it should be Volvo part number 3545976? Just replace the receptacle housing...
