(b) Dismount the coolant temperature sensor.
04
CAUTION

Engine coolant temperature sensor shall be dismounted in cold vehicle status (or
water temperature ≤ 40℃).

(c) Use a multimeter to measure the resistance
of engine coolant temperature sensor at
different water temperature, and its reference
value shall conform to the items listed in the
table below.

Temperature
50 85 110 115
(℃)

Resistance
226 ± 35 64 ± 8 28 26.4 ± 2
（Ω）

Check whether the result is normal?

Yes> go to step 2
No > Replace the coolant temperature sensor

2 . Check the signal circuit of engine coolant temperature sensor.

(a) Ignition Switch: OFF.

(b) Disconnect the connector E09 of engine
coolant temperature sensor.
(c) Ignition Switch: ON.
