Inspection Of Mat (Manifold Temperature) Sensor; Inspection Of Map Sensor (Manifold Air Pressure Sensor); Inspection Of Starter Solenoid - TOHATSU TLDI MD 115A SERIES Service Manual

Electrical System
17) Inspection of MAT (Manifold
Temperature) Sensor
1. Measure MAT sensor resistance. Replace if other than
specified value.
This test can be made without removing parts.
MAT (Manifold Temperature) Sensor
Temperature (Reference Value) :
2.35 - 2.55kΩ at 20˚C (68˚F)
0.30 - 0.35kΩ at 80˚C (176˚F)
18) Inspection of MAP Sensor (Manifold
Air Pressure Sensor)
Apply 5V between terminals b and c, and measure
1.
output voltage between terminals a and b.
Replace MAP sensor if the output voltage is out of
specified range.
This test can be made without removing parts.
Output Voltage between a and b : @25˚C
(77˚F) and atmospheric pressure
3.1 - 4.6V

19) Inspection of Starter Solenoid

This test can be made without removing parts.
1. Connect tester lead wires to both terminal of starter
solenoid.
2. Connector green (G) lead wire to battery positive terminal.
3. Connector black (B) lead wire to battery negative terminal.
4. Check electrical conductivity between terminals of starter
solenoid. Replace if no conductivity.
5. Remove battery terminal from green (G) or black (B) lead
wire, and check there is no conductivity between starter
solenoid terminals. Replace if conductive.
