No need to pull it out.

Carefully disconnect the wire clip and disconnect the plug on the WUR. It's a little tricky, use a tiny screwdriver.

Set your OHM meter to a low scale OHM reading and carefully touch each probe to the 2 pins inside the plug connection. It doesn't matter which way the probes go on the 2 pins. The internal battery in the meter sends a current through the WUR to check resistance of the inner winding.

You may want to check calibration on your meter first by letting the probes touch each other and using the adjusting feature to calibrate to zero.

Hope it's a digital meter and not analog? With a fresh battery?

Let us know how many OHMS you find.

Even if the range is good, it doesn't mean proper function of the WUR. For that, use CIS pressure gauges like John says.
