Howdy! "Long time listener, first time caller" here. A couple years ago I was lucky enough to get one of my dream cars, a 300zx, and all was well until it wasn't. A long story made not so long..
A friend of mine received a 1992 300zx NA 2+2 from his dad. He already had a good running car and doesn't know how to use a manual transmission, so he sold it to me. When I got the car it ran good, not great, but well enough to travel about 1500 miles back to my house. I've done a bunch of minor stuff like spark plugs, ignition coils, air filter, fuel filter and so on. The issue I am attempting to tackle now seems to be centered around the speedometer. Last year the cruise control stopped working and the speedometer became intermittent, at the time I didn't notice any issues with the power steering. Eventually the speedometer stopped displaying anything completely, but power steering continued to work until about 6 weeks ago.
I want to go back to using to using the car as a semi-daily driver, but its difficult without power steering (health issues). I've been trying to understand this wiring diagram I had found, unfortunately I don't recall exactly where I found it, maybe here? Anyways, before I go way off-topic, is anyone aware of which pin actuates the power steering solenoid or is it completely isolated from the ECU? I don't really trust the "Online AI Search Tools" which are telling me that it is Pin 4 on the ECU connector since that should be part of the Idle Air Control system.

Not off a Z hence why I thought I'd post here.
It's off a 92 peugeot 205 1.8 diesel.
Done some research online and the consensus seems to be that the best way to test a coolant sensor is to measure the resistance with a multimeter.
Video of soime chap doing it here:
From what I can make out, I should be testing the resistance across the two pins on the back of the sensor.
When I took the sensor out the car and did this I got no result, zip. Aha I thought it's bust! Bought a new one but that does the same :blink:
After poking around a bit I found I can get a measurement if I touch one of the pins and the brass casing.
Does this sound right or are both my sensors bust?
When my multimeter leads are not in contact with anything they show the same as the top pic e.g. '1'
