2) Check battery voltage at (+) terminal of harness cou-
pler.
If no battery voltage, check the fuse and continuity of
wireharness.
Sample data is 0.979V.
3) Water temperature sensor check
• Disconnect the coupler from the water tempera-
ture sensor and measure the resistance referring
to the figure at right.
The temperature vs. resistance curve must meet
the criteria listed below.
