Lexus RX (RX 350L, RX450h) 2016-2026 Repair Manual: Inspection
INSPECTION
PROCEDURE
1. INSPECT NO. 1 COOLER THERMISTOR
(a) Measure the resistance according to the value(s) in the table below.

| *a | Component without harness connected (No. 1 Cooler Thermistor) | *b | Sensing Portion |
| *c | Resistance (kΩ) | *d | Temperature (°C (°F)) |
| *e | Allowable Range | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 1 - 2 | -10°C (14°F) | 7.30 to 9.10 kΩ |
| -5°C (23°F) | 5.65 to 6.95 kΩ | |
| 0°C (32°F) | 4.40 to 5.35 kΩ | |
| 5°C (41°F) | 3.40 to 4.15 kΩ | |
| 10°C (50°F) | 2.70 to 3.25 kΩ | |
| 15°C (59°F) | 2.14 to 2.58 kΩ | |
| 20°C (68°F) | 1.71 to 2.05 kΩ | |
| 25°C (77°F) | 1.38 to 1.64 kΩ | |
| 30°C (86°F) | 1.11 to 1.32 kΩ |
If the resistance is not as specified, replace the No. 1 cooler thermistor.
NOTICE:
- Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.
- When measuring, the sensor temperature must be the same as the ambient temperature.
HINT:
As the temperature increases, the resistance decreases (see the graph).
