1. Disconnect the connector from the wiring harness connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   E26-120 (THO1) - E8-13 (OIL)	Always	Below 1 Ω
   E26-119 (ETHO) - E8-12 (E2)	Always	Below 1 Ω
   E26-120 (THO1) or E8-13 (OIL) - Body ground and other terminals	Always	10 kΩ or higher
   E26-119 (ETHO) or E8-12 (E2) - Body ground and other terminals	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the wiring harness connector from the transaxle.

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

   Standard Resistance

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