CAUTION
Use care when testing electrical connectors.
Do not damage connector pins or sockets
with multimeter probes. Failure to comply
may result in damage to equipment.
NOTE
Inspect connector pins/sockets for damage,
corrosion, and serviceability. Check that
connector pins are not pushed back and
are capable of making good contact.
RESISTANCE TEST
(1) Set multimeter to ohms.
(2) Connect positive (+) probe of multimeter on
P119a.
NOTE
Transmission sump oil temperature sensor
resistance reading is affected by temperature.
Refer to Table 2-19. Transmission Sump
Oil Temperature Sensor Resistance Readings
for details.
(3) Connect negative (-) prove of multimeter on
P119d and note reading on multimeter.
(4) Connect negative (-) probe of multimeter to
all other pins in connector P119, one at a
time, and note reading on multimeter.
(5) Connect negative (-) probe of multimeter to
ground and note reading on multimeter.
(6) Connect positive (+) probe of multimeter to
connector P119d.
(7) Connect negative (-) probe of multimeter to
all other pins in connector P119 (except
(P119a), one at a time, and note reading on
multimeter.
(8) Connect negative (-) probe of multimeter to
ground and note reading on multimeter.
(9) If correct resistance is not present in step 3,
or continuity is present in step 4, 5, 7, or 8,
notify DS Maintenance.
(10) If correct resistance is present in step 3 and
continuity is not present in step 4, 5, 7, or 8,
replace WTEC II TEPSS (para 8-2).
