5. Disconnect connector 751,
connector
X173,
and
connector on transmission
ECU.
6. Check for continuity to
chassis at connector 751 pin 7,
connector
X173
pin
6,
connector 751 pin 8, and
connector X173 pin 7.
a. If continuity is present, repair
or replace connectors (WP
0111 00).
b. If wiring harness must be
replaced, notify SRA.
7. Perform internal resistance
check on turbine speed sensor.
Resistance should be 1050 +/-
100 ohms.
If resistance is not as specified,
replace turbine speed sensor (WP
0095 00).
8. Perform continuity check
between turbine speed sensor
pin 1 and pin 2 and chassis.
If continuity is present, replace
turbine speed sensor (WP 0095
00).
