No. On the intake, just past the throttle body. It is usually hidden under the cover over the throttle cable attachment.

I wonder if it would make any sense to pull the connector off the ECT sensor and plug in a potentiometer or resistor in its place for testing.

One screw clamp at the throttle body. It is also easier to remove the cover (one screw over the vacuum tree) to get at the accordion screw clamp. You would be amazed at how much gunk is on the butterfly valve in the throttle body anyway, once you get clamp and tube off.

Ohok, so i guess you have to take that one big hose clamp off.
I’ve been driving a Volvo long before anyone ever paid me to drive one.
That's probably because I've been driving one since 2015 and nobody has offered to pay me yet.

What is a vacuum tree?

The vacuum tree is the plastic piece that fits in the top of the intake manifold and has multiple vacuum ports. It's on the right on my 96.

You can see it in the middle of the right edge of this picture. Right were that white vacuum line comes into the picture. You need to remove the cover that's over all of this mess to get at it.

Nice pic BTW.

Yeah, that will do it, it'll still get sucked in.MrAl wrote: ↑07 Jan 2023, 09:41Ok i guess that ECT will have to be checked again at some point. Just had it replaced about a year ago.Chuck W wrote: ↑07 Jan 2023, 06:40 There's also a vacuum tree on the intake you could shoot some in, without having to mess with opening the throttle.
I'm also going to suggest (re)checking the ECT sensor and connector. I had a bad one that really gave me fits when it was cold. It ran marginally bad when it was cool, but when it got cold, it wouldn't start, and was unhappy with any attempts to make it start.
You mean shoot some in where the air filter is?
