Inspection Of Throttle Position Sensor; Inspection Of Water Temperature Sensor - TOHATSU TLDI MD 115A SERIES Service Manual

Electrical System

12) Inspection of Throttle Position Sensor

1. Measure resistance between terminals.
Replace throttle position sensor if the resistance is out of
specified range.
This test can be made without removing parts.
When lever is at position A (wide open throttle) :
Between a - c
Between e - g
Between a - b
Between e - f
When lever is at position B (fully closed throttle) :
Between a - c
Between e - g
Between a - b
Between e - f

13) Inspection of Water Temperature Sensor

Remove the part and test it as a separate unit.
1. Remove water temperature sensor from engine.
2. Put water temperature sensor in the water, and warm up
water slowly.
3. Measure water temperature sensor resistance. Replace if
other than specified value.
Water Temperature Sensor Resistance
