[QUOTE="wallypiper, post: 176129, member: 2685"] I don't know what value you changed, but according to the service manual I have (LIT-11616-FJ-02), the fan swtich point is not adjustable. The sensor is a swtich, not an analog transmitter or transducer. On temperature rise, it should close at 105C. On temperature fall, it should open at 100C. So, whatever it was you changed, it should not affect the operation of the fan. Although the ON/OFF signal is processed by the ECU, the switch points are fixed by the sensor and not adjustable. The ECU sees the sensor/switch close and turns on a relay which turns on the fan. When the ECU sees the sensor/switch open again, it turns the relay off which turns the fan off. [/QUOTE]
