Repair Procedures: Inspection
[Resistance Inspection]
- Turn the Ignition Switch OFF.
- Remove the OTS. (Refer to "Removal" procedure below).
- After immersing the thermistor of the sensor into engine coolant, measure resistance between the OTS terminals 1 and 2.
- Check that the resistance is within the specification.OTS TERMINALS 1 & 2 RESISTANCE
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]
- Connect the GDS to DLC.
- Turn the ignition ON or idle.
- Check the OTS temperature in the GDS service data.
- Check that the resistance is within the specification.
