b. Check engine ECU and
sensor harness connector
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).
6. Disconnect sensor harness
from engine ECU and place
ignition
switch
in
ON
position.
7. Measure voltage from engine
ECU connector pins 17 and
37 to ground. Voltage should
be 4.75-5.25V.
If voltage is not as specified,
replace engine ECU (WP 0078
00).
8. Place ignition switch to OFF
position
and
disconnect
sensor harness from engine
ECU, ambient air pressure
sensor, and intake manifold
pressure sensor.
9. Measure resistance from
sensor harness pins 17 and 37
to engine block ground.
Resistance should be greater
than 100k ohms.
If engine harness requires
replacement, notify SRA.
4.75-5.25V
