Sensor Resistance at Various
Temperatures
If a sensor error is suspected, perform the following:
1. Examine the wiring, ensuring continuity from con-
troller to sensor(s).
2. Using a multimeter, measure resistance of sen-
sor(s) and compare the value with the Table L
below.
3. If all okay, replace main control board.
