Measure the resistance of each pressure control solenoid (PCS) between terminals.

IMPORTANT: The resistance of the solenoid can become infinity ohm when the resistance measurement is made at high temperatures.

If the resistance value is not between the minimum and maximum resistance plot lines, then measure the solenoid resistance at 20°C (68°F).
If both resistance measurements are not between the minimum and maximum resistance plot lines, then replace the PCS.
