Looking for temperature sensor parameters, vacuum solenoid pinout?

Hello, there are 7 wiring diagrams in total that are listed for different system types, I'll just post them all and you can go through and see what wire colors you have, there is also a vacuum diagram with the solenoid block that shows the different routes vacuum would be applied for panel, defrost, floor, etc. I'll post that as well. These older diagrams can be somewhat limited, but it sounds like you have an idea of what you're doing, ill also search for any additional info on the temperature sensors, there are a couple different ones. But they should use a 5volt reference I'd think, just as temperature sensors do now. So unplugged you would read 5volts on one of the temperature sensors 2 wires, then plugged in the resistance of the sensor would pull the voltage lower for a signal back to its control module.

On most outside Ambient temperature sensors, they usually show up on the Cluster once the key is On. Or there is a small display somewhere on the dash. Because I don't see any outside temp reading on the ATC display panel, I'll post all the information I found so far, it does show the location of the Ambient outside temp sensor, the temp sensor in the vehicle is labelled as "In-Car Sensor". But there's 16 pages so far you can go through.

Here's all the wiring diagrams, operations, a diagnostic flow chart, the ATC display and the Vacuum routing diagrams. I'll look for the outside temperature display location as well but see if any of this helps.

If you're looking for a resistance value per temperature, I would think on an older vehicle like this the inside temperature sensor is probably the same resistance. The only temp sensor that might be different that reads air temperature would be the intake air temperature sensor, since that reads air being drawn into the engine and is in a much different environment. But an ambient temperature sensor for a display on this is most likely going to be the same resistance value as the In-Car, I didn't see any different part number for those 2 sensors, the coolant temp sensor is a different story, those cannot read air temperatures correctly, they are designed for coolant readings only.

I will check on that right now.

Sorry for the delay, they had a page for each code, but check out pages 14 and 15, it shows the resistance value of the temperature sensors at different temperatures.

Glad to help, Poland huh. Well, keep warm up there. We get people from all over the world, it is always interesting to hear where they are from. Hope your build goes well.

Gotta be creative sometimes like this. I know I end up building my own testing equipment sometimes when I don't want to spend a thousand dollars. But I hope for the best for you.
