Inspection Of The Throttle Position Sensor (Tps); The Starting System (Except For Mf); Inspection Of The Fuse; Inspection Of The Starter Solenoid - TOHATSU MFS 25D Service Manual

5) Inspection of the Throttle Position
Sensor (TPS)
1. Check the throttle position sensor resistance. Replace the
entire throttle body if the value is not as specified.
Resistance Between Terminals:
Apply a voltage of 5 V between Vta 1 and E2 2 and
2.
check the change in voltage between 2 and Vc 3.
The TPS output is proportional to the degree the
main valve is open, from fully closed to fully open.
6. The Starting System
(Except for MF)

1) Inspection of the Fuse

1. Check the conductivity of the fuse. Replace it if it is not
conductive.
A flat, compact blade fuse is used.

2) Inspection of the Starter Solenoid

1. Connect the lead wires of the tester to the terminals of the
starter solenoid.
2. Connect the green (G) lead wire to the battery's positive
terminal.
3. Connect the black (B) lead wire to the battery's negative
terminal.
4. Check the conductivity between the terminals of the starter
solenoid. Replace it if it is not conductive.
5. Remove the green (G) or the black (B) lead wire from a
battery terminal and check that there is no conductivity
between the terminals of the starter solenoid. Replace it if
it is conductive.
