connector. Resistance should
be more than 100k ohms.
If
engine
harness
requires
replacement, notify SRA.
b. Measure resistance from
sensor harness connector pin
25 to all other pins in
connector. Resistance should
be more than 100k ohms.
If
engine
harness
requires
replacement, notify SRA.
c. Measure resistance from
sensor harness connector pin
45 to all other pins in
connector. Resistance should
be more than 100k ohms.
If
engine
harness
requires
replacement, notify SRA.
d. Measure resistance from
actuator harness connector
pin 19 to all other pins in
connector. Resistance should
be more than 100k ohms.
If
engine
harness
requires
replacement, notify SRA.
e. Measure resistance from
actuator harness connector
pin 29 to all other pins in
connector. Resistance should
be more than 100k ohms.
If
