Hello!

When I test my AFM air temp sensor, it comes back at 170 ohms, which is way too low. I looked through my spare parts and I found an old AFM with part number A31-622 420 

 

Would this AFM work in my 78?

Your test result sounds suspiciously like the AFM's built in 180 Ohm (ish) resistor. Are you sure you're measuring the correct terminals for the temperature sensor?
