temp sensor connector

Post by mapdoc »

I was changing out the temp sensor on my '97 850 T5 and discovered that the plastic connector that the temp sensor plugs into has disintegrated and I cant keep the temp sensor plugged in.What type of connector housing do I need? It's black plastic that holds two female wire terminals.

Thanks

It really isn't something that you can source off the shelf. If you can find a good one at a pick n pull you can splice it in place of the bad one. Push comes to shove, you can just splice around the connector altogether and it will work fine but it sets up a real PITA later on.

Volvo does sell the connectors but you will need to work with the dealership to get the right one. They don't call them out by function in VIDA but they do have pictures and you can match it that way. They typically come with pins that you crimp on and then slip the pins into the plastic shell.

It's a vital connection and can wreak havoc if it isn't solid. Nice post recently on all this. As stated above look for a good connector at Pic-N-Save, I'm going through having to deal with this and it's a PIA because in order to have really good access to this part in order to repair you have to move the power steering hose and upper rad hose out of the way. Next time I have to drain coolant I'll do this. I am now tuned in to looking for these connectors when I'm on a mission @ Pic-N-Save. Along with all the hose clamps I can find (Mercedes clamps are the best).

Yes, yours was the one I was referring to. Scared me into thinking I need to do this right sooner rather than later. When I went to do this I backed off realizing this is not a quick fix. But I have a hackneyed job in place now!

Thanks. More of a hassle than difficult. You need to be good with a hot iron. Adding a bit of length to the female end allows one more flexibility to move the harness wires further away from the hot IM and improves future access.

I've learned than on '98's there is only ONE engine temp sensor and that's it. EVERYTHING temp-wise depends on and is based off of the ECT. I think 99 and onward use at least two sensors. Indy has said that a faulty ECT will tank your mileage, make it hard to start, trigger a O2 sensor warning and shorten the life of the cat-con if not quickly fixed!!

Yikes......
