Getting delta p warning again. New valve and sensor last year. Want to know if there is a way to check the sensor before digging the valve out of its cave?

On a CM871, I will sometimes check EGR valves by removing the venturi pipe. With the pipe removed, unplugging the EGR temperature sensor will close the valve fully, should stop egr gas flow, and having it plugged in will cause egr valve to open full blast and have a ton of egr gas flow.
