I have a 90 Chrysler New Yorker. I have replaced the temp sensor twice, but no reading and throwing a code. What is the best way to check for voltage and what should it be reading? I know it's not the actual sensor at this point, but not sure how to remedy this issue.
I'm used to working on a Ramcharger where I have more room, and no electrical gremlins like this car.

Welcome To TD!!!
I am a little bit confused by the wording in your post "no reading" but "throwing a code".
I assume we are working with the Coolant Temperature Sensor for the Engine Controller since you stated Code 22 and not the Temperature Sending Unit for the Gauge.

Diagnosing a Code 22 is fairly simple...
You will need to determine actual CTS voltage, if the 5 volt reference is present,if the signal return line has continuity back to the engine controller and is not shorted to ground.
I can post all of this in detail and walk you through the diagnostics, just need to know...
What engine is in this car?
