FI SYSTEM DIAGNOSIS 4-49
“C15” (P0115-H/L) ECT SENSOR CIRCUIT MALFUNCTION
INSPECTION
Step 1 (When indicating C15:)
1) Turn the ignition switch OFF.
2) Lift and support the fuel tank. (
5-3)
3) Check the ECT sensor coupler for loose or poor contacts.
If OK, then measure the ECT sensor voltage at the wire side
coupler.
4) Disconnect the coupler and turn the ignition switch ON.
5) Measure the voltage between B/Bl wire terminal
A
and
ground.
6) If OK, then measure the voltage between B/Bl wire terminal
A
and B/Br wire terminal
B
.
ECT sensor voltage: 4.5 – 5.5 V
