10.Measure resistance from pin
6 of sensor harness connector
to all other pins in connector.
Resistance should be greater
than 100k ohms.
a. If resistance is as specified,
replace ambient air pressure
sensor (WP 0093 00).
b. If engine harness requires
replacement, notify SRA.
11.Place ignition switch in OFF
position. Disconnect sensor
harness connector from ECU.
12.Inspect sensor harness and
ECU connectors for dirty,
corroded,
bent,
broken,
pushed back, and extended
pins.
Clean and repair connector(s) as
required (WP 0111 00).
13.Check sensor harness and
ECU 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).
