This is out of the 03 manual.Should be the same as yours unless yours is efi. Should be the same process for efi but maybe differnt ohm vaules. Hope this helps
1. Disconnect the main wiring harness connector
from the temperature sensor.
2. Connect an ohmmeter between the sensor terminal
and any convenient chassis ground (or any brown
wire). The ohmmeter must read less than 20 ohms
of resistance with the water temperature more than
+230°F. The ohmmeter must read no resistance
with the water temperature less than +190°F.
NOTE: It may be easier to remove the sensor
from the water manifold for testing purposes.
Immerse the sensor body (only up to the threads)
in automatic transmission fluid and slowly heat
the fluid. The ohmmeter must indicate the above
resistances when connected between the sensor
terminal and the sensor body/chassis.
