Repair Procedures: Inspection

[Resistance Inspection] 

1. Turn the ignition switch OFF.
2. Remove the OTS. (Refer to "REMOVAL ")
3. After immersing the thermistor of the sensor into engine coolant, measure resistance between the OTS terminals 1 and 2.
4. Check that the resistance is within the specification.

   Temperature		Resistance (kΩ)
   °C	°F
   -40	-40	52.15
   -20	-4	16.52
   0	32	6.0
   20	68	2.45
   40	104	1.11
   60	140	0.54
   80	176	0.29
   100	212	0.16
   120	248	0.10

[Voltage Inspection] 

1. Connect the GDS to DLC.
2. Turn the ignition ON or idle.
3. Check the OTS temperatuere in the GDS service data.
4. Check that the resistance is within the specification.
