For 1990-2009 cars only
- Measure the resistance of each pressure control solenoid (PCS) between terminals.
- 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.
Important: The resistance of the solenoid can become infinity ohm when the resistance measurement is made at high temperatures.
