Circuit Failure - Continued
10.Place ignition switch in OFF
position, disconnect actuator
harness
connector
from
engine ECU, and disconnect
fuel inlet restriction sensor
from engine harness.
a. Measure resistance from
actuator harness connector
pin 27 to engine block
ground. Resistance should
be greater than 100k ohms.
a. If resistance is as specified,
repair or replace connectors
(WP 0111 00).
b. If engine harness requires
replacement, notify SRA.
b. Measure resistance from
actuator harness connector
pin 28 to engine block
ground. Resistance should
be greater than 100k ohms.
a. If resistance is as specified,
repair or replace connectors
(WP 0111 00).
b. If engine harness requires
replacement, notify SRA.
c. Measure resistance from
