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

   Standard Resistance

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

   HINT: 

   If the resistance is out of the specified range with the ATF temperature shown in the table below, the driveability of the vehicle may decrease.

   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
