Cavity 1 temperature in unlocked cavity too

From Service Manual 973973, p.25:

1.Check element operation; check temperature sensor resistance; check for stuck relays; replace control module if necessary.

2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).

3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
