Temp sensor test (
test
)
This menu will allow you to check the resistance the control box is reading from the water
temp sensor. This can be used for a diagnostic tool if you are having troubles or feel that the
reading is incorrect. For the Dakota Digital SEN-04-5 the resistance decreases as temperature
increases. Typical values for the Dakota Digital SEN-04-5 sensor are:
100F - 500 ohms
200F - 75 ohms
300F - 19 ohms
If the message display is showing “
EEE
” this is an open connection or no sensor connected. If it
is reading “
---
” this is indication of a short.

” is displayed press and hold SW1 until the message screen changes.
Release SW1 and the current resistance from the fuel level sensor will be displayed as
“ test temp ” “ xxx ohms ” where xxx is the resistance seen at the control box.
