b. Measure resistance from
sensor harness connector
pin 39 to all other pins in
connector.
Resistance
should be more than 100k
ohms.
a. If resistance is as specified,
replace
intake
manifold
pressure sensor (WP 0093
00).
b. If resistance is not as
specified, notify SRA.
9. Turn ignition switch to OFF
position, disconnect intake
manifold pressure sensor
from engine harness, and
disconnect sensor harness
from engine ECU.
10.Measure resistance from
sensor harness connector pin
39 to intake manifold pressure
sensor connector pin C.
Resistance should be less than
10 ohms.
If engine harness requires
replacement, notify SRA.
