POWER STEERING OIL PRESSURE SWITCH
1) Power steering oil pressure switch is mounted on power
steering pump. Disconnect single wire connector at switch. Start
engine.
2) Connect ohmmeter between switch terminal and ground. If
continuity is present with steering wheel in straight-ahead position,
replace switch. If continuity is not present while turning steering
wheel, perform POWER STEERING IDLE-UP SYSTEM TEST. See IDLE-UP SYSTEMS
under IDLE CONTROL SYSTEM.
THROTTLE POSITION SENSOR
1) TPS is mounted to throttle body, at end of throttle shaft.
Disconnect TPS connector. See Fig. 6. Using ohmmeter, measure total
resistance between TPS connector terminals as specified in TPS
CONNECTOR TERMINAL IDENTIFICATION table. If resistance is not 3500-
6500 ohms, replace TPS.
2) Using an analog (needle-type) ohmmeter, measure variable
resistance between TPS connector terminals as specified in TPS
CONNECTOR TERMINAL IDENTIFICATION table.
3) Operate throttle valve from closed to wide open throttle.
If rate of resistance does not change smoothly within 3500-6500 ohms
throughout range of throttle valve movement, replace TPS.

REMOVAL & INSTALLATION
Removal
1) Remove negative battery cable. Remove transfer case skid
plate (if equipped). Scribe alignment marks and remove both drive
shafts. Drain oil from transfer case. Disconnect wiring harness from
back-up light switch, all 4WD switches and any other electrical
connectors (if equipped).
2) Disconnect speedometer cable from drive. Unclip cable from
case. Place transfer case shifter in "2H" position and transmission in
Neutral. Remove 6 bolts holding control lever assembly. Remove control
lever assembly and gasket.
3) Remove select plunger bore plug at right side of case.
Remove select spring and plunger. Remove change shifter spring pin.
Remove change shifter. Remove transfer case mount. Remove 4 bolts and
2 nuts holding transfer case to adapter. Remove transfer case from
vehicle.
Page 1155 of 1333
Installation
1) Position transmission shifter in Neutral and transfer case
lever in "2H" position. Install neutral return plungers and springs in
holes on top of adapter. Tighten plug until it is flush with adapter
surface. Cover plug threads with sealant.
2) Coat inside of change shifter with grease. Ensure change
shifter pin protrudes 1/8" above change shifter when installed. Mount
detent plunger spring and install plug (if equipped). To complete
installation, reverse removal procedure. Fill transfer case with API
GL-4 or higher 75W-90 or 75W-85W gear oil.
