"C23" TO SENSOR CIRCUIT MALFUNCTION

DETECTED CONDITION
The sensor voltage should be the following for 2 sec.
and more after ignition switch turns ON.
0.2 V Sensor voltage
INSPECTION
Step 1
1) Remove the seat. ("7-4)
2) Turn the ignition switch OFF.
3) Check the TO sensor coupler for loose or poor contacts.
If OK, then measure the TO sensor resistance.
4) Remove the TO sensor.
5) Measure the resistance between A and B terminals.
% TO sensor resistance:
! 09900-25008: Multi circuit tester set
& Tester knob indication: Resistance (Ω)
Is the resistance OK?
YES Go to Step 2
NO Replace the TO sensor with a new one.
4.6 V
19.1 – 19.7 kΩ (A – B terminals)
