“C15” (P0115-H/L) EOT SENSOR CIRCUIT MALFUNCTION
INSPECTION
Step 1 (When indicating C15:)
1) Turn the ignition switch OFF.
2) Check the EOT sensor coupler for loose or poor contacts.
If OK, then measure the EOT sensor voltage at the wire side
coupler.
3) Disconnect the EOT sensor coupler and turn the ignition
switch ON.
4) Measure the voltage between B/Bl wire terminal
1
and
ground.
5) Also, measure the voltage between B/Bl wire terminal
1
and
B/G wire terminal
2
.
