Voltage reading on circuit board

Hi there,

I have a prr error code on my panel which suggest the temerature regulation probe. If I disconnect the probe at the circuit board and put a volt meter on each of the 4 legs on the board where the connector block goes; should I expect a reading? I've tried and have nothing, does this suggest the circuit board needs replacing?

very many thanks for help

You probably wont get a reading there. Usually when you get an error code like this it is best to replace the sensor.
