Error Code 1581 - Fuel Inlet Restriction Sensor
Circuit Failure - Continued
11.Place ignition switch in OFF
position, disconnect actuator
harness connector and sensor
harness
connector
from
engine ECU, and disconnect
fuel inlet restriction sensor
from engine harness.
a. Measure resistance from
actuator harness connector
pin 27 to all other pins in
actuator
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.
b. Measure resistance from
actuator harness connector
pin 27 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.
c. Measure resistance from
actuator harness connector
pin 28 to all other pins in
actuator
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.
