7. Place ignition switch to OFF
position
and
disconnect
actuator harness connector
from engine ECU.
a. Inspect harness connector
and engine ECU connector
for dirty, corroded, bent,
broken, pushed back, and
extended pins.
Clean and repair connector(s) as
required (WP 0111 00).
b. Check harness and engine
ECU for dirt or moisture in

missing
or
damaged
connector seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP
0111 00).
8. Place ignition swtich in OFF
position, disconnect actuator
harness
connector
from
engine ECU, and disconnect
fuel inlet restriction sensor
from engine harness.
9. Measure resistance from
actuator harness connector
pin 27 to pin B (or 2) of 3 pin
connector
at
sensor.
Resistance should be less than
10 ohms.
a. If resistance is as specified,
repair or replace connectors
(WP 0111 00).
b. If engine harness requires
replacement, notify SRA.
