d. Measure resistance from
actuator harness connector
pin 28 to all other pins in
sensor
connector.
Resistance
should
be
greater than 100k ohms.
a. If resistance is as specified,
replace fuel inlet restriction
sensor (WP 0093 00).
b. If resistance is not as
specified, notify SRA to
replace engine harness.
e. Measure resistance from
actuator harness connector
pin 29 to all other pins in
actuator
connector.
Resistance
should
be
greater than 100k ohms.
a. If resistance is as specified,

CORRECTIVE ACTION
Error Code 1582 - Fuel Inlet Restriction Sensor
Circuit Failure
1. Place ignition switch to OFF
position and disconnect fuel
inlet restriction sensor from
engine harness (WP 0093 00).
a. Inspect fuel inlet restriction
sensor
connector
and
engine harness connector
for dirty, corroded, bent,
broken, pushed back, and
extended pins.
Clean and repair connector(s) as
required (WP 0111 00).
b. Check fuel inlet restriction
sensor and engine harness
for dirt or moisture in or on
connector and for missing
or
damaged
connector
seals.
Remove dirt and moisture from
connector. Replace missing or
damaged connector seals (WP
0111 00).
