2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   18 (THO1) - 17 (E2)	Always	79 Ω to 156 kΩ
   18 (THO1) - Body ground	Always	10 kΩ or higher
   17 (E2) - Body ground	Always	10 kΩ or higher

   HINT: 

   If the resistance is out of the specified range at any of the ATF temperatures shown in the table below, the driveability of the vehicle may decrease.

   Resistance (Reference)

   ATF Temperature	Specified Condition
   10°C (50°F)	5 to 8 kΩ
   25°C (77°F)	2.5 to 4.5 kΩ
   110°C (230°F)	0.22 to 0.28 kΩ
