The next step will give you general guidance on how to test a new high pressure sensor.

Install your replacement pressure sensor and reassemble the pressure cooker.

Add 3 cups of water to the pressure cooker and set it to cook on high pressure for five minutes.

If the emergency vent begins to leak or vent during the heating cycle, the pot is over-pressurizing. Immediately unplug the pressure cooker and perform a quick release.

Once the five minutes are up, vent using quick release.

There should be a strong pressure release. If there isn't, the pressure cooker is not reaching sufficient pressure.

If the emergency vent didn't leak during the cycle and the quick release vented with strong pressure, your new pressure sensor is working as intended. You don't need to calibrate the sensor.
