Check the resistance between EVT control solenoid valve terminals as per the following.

EVT control solenoid valve		Condition		Resistance
Terminal		Condition		Resistance
1	2	Temperature	20°C (68°F)	6.7 – 7.7 Ω

Check the resistance between EVT control solenoid valve terminal and solenoid valve body.

EVT control solenoid valve	—	Resistance
Terminal	—	Resistance
1	Solenoid valve body	Not existed
2	Solenoid valve body	Not existed

Is the inspection result normal?
