Mitsubishi Montero (1998+). Manual - part 42

         Disconnect electrical connector from coolant temperature

sensor. Using ohmmeter, check resistance between terminals of coolant

temperature sensor. Resistance should be as specified in accordance

with the TEMPERATURE-TO-RESISTANCE VALUES table. Replace coolant

temperature if resistance is not within specification.

TEMPERATURE-TO-RESISTANCE VALUES

Temperature 



F (



C)                                               Ohms

32 (0)  .........................................................  5.8

68 (20)  ........................................................  2.4

104 (40)  .......................................................  1.1

176 (80)  .......................................................  0.3

         INPUT SPEED SENSOR

         Disconnect solenoid and sensor connector. Using ohmmeter,

measure resistance between terminals No. 9 and No. 10. See  Fig. 9.

Resistance should be 560-680 ohms at 68



F (20



C). If resistance is not

as specified, replace No. 2 speed sensor.

         OIL TEMPERATURE SENSOR

         Disconnect solenoid and sensor connector. Using ohmmeter,

check resistance between sensor connector terminals No. 1 and No. 2.

See Fig. 9. Resistance should be 10 k/ohms when oil temperature is

77



F (25



C). With oil temperature at 248



F (120



C), resistance should

be 615 ohms. If resistance is not as specified, replace oil

temperature sensor.

         OUTPUT SPEED SENSOR

         Disconnect solenoid and sensor connector. Using ohmmeter,

measure resistance between terminals No. 3 and No. 4. See  Fig. 9.

Resistance should be 560-680 ohms at 68



F (20



C). If resistance is not

as specified, replace output speed sensor.

         OVERDRIVE SWITCH

         Using a screwdriver, remove overdrive switch from selector

lever, located below selector lever button. Using a DVOM, check

continuity between overdrive switch terminals No. 3 and 5 with switch

in ON position. Continuity should exist. With switch in OFF position,

check continuity between terminals No. 3 and 4. Continuity should

exist. If continuity is not as specified, replace switch. See  Fig. 10.

         PARK/NEUTRAL POSITION (PNP) SWITCH

         Disconnect PNP switch harness connector. Using ohmmeter,

check continuity between specified terminals. See  Fig. 11. Replace as

needed.

         PATTERN SELECT SWITCH

         Using a screwdriver, remove pattern select switch from

console. Switch is located at rear of selector lever, to right of

emergency brake handle. Using a DVOM, check continuity between pattern

select switch terminals No. 1 and 2, with switch in HOLD position.

Continuity should exist. With switch in POWER position, check

continuity between terminals No. 1 and 6. Continuity should exist. If

continuity is not as specified, replace switch. See  Fig. 12.

         SOLENOIDS

         For solenoid testing, refer to the appropriate DTC under

DIAGNOSTIC TESTS. To check solenoid operation, apply battery voltage

to appropriate terminal of TCM connector and ground. Ensure operating

sound can be heard when battery voltage is connected. Replace solenoid

if operating sound cannot be heard.

         THROTTLE POSITION (TP) SENSOR

         For diagnostic and testing information, see appropriate SELF-

DIAGNOSTICS article in ENGINE PERFORMANCE section.

         4WD LOW RANGE DETECTION SWITCH

         For location and testing information on 4WD low range

detection switch, see appropriate article in AXLE SHAFTS & TRANSFER

CASES.

         TCM PIN VOLTAGE CHARTS

         Access TCM. See Fig. 1 or 2. Turn ignition on. Using DVOM,

backprobe TCM connector. See Fig. 13. Check voltage between designated

terminals on TCM connector and ground. See TCM TERMINAL VOLTAGE

SPECIFICATIONS table. Voltage should be as specified.
