Throttle Valve Body/A/T Clutch Pressure Control
Solenoid Valve
Test
1. Connect the No. 4 (RED: +) terminal of the shift
solenoid valve/A/T clutch pressure control solenoid
valve harness connector to the battery positive ter-
minal and the No. 3 (WHT: -) terminal to the battery
negative terminal. Check that the throttle valve
moves.

NOTE: Do not adjust or remove;
this is adjusted at the factory.
2. Disconnect the battery terminals, and check that the
throttle valve releases.
3. Repeat steps 1 and 2.
NOTE: You can see throttle valve movement
through the fluid passage in the attaching surface of
the throttle valve body.
4. If the throttle valve binds, or moves sluggishly, or if
the A/T clutch pressure control solenoid valve does
not operate, replace the throttle valve body/A/T
clutch pressure control solenoid valve assembly.
5. If the A/T clutch pressure control solenoid valve
does not operate, disconnect the A/T clutch pres-
sure control solenoid valve harness from the A/T
clutch pressure control solenoid valve. Connect the
battery terminals directly to the A/T clutch pressure
control solenoid valve.
6. If the A/T clutch pressure control solenoid valve
operates after connecting the battery, and the throt-
tle valve movement is OK, replace the shift solenoid
valves A and B.

Throttle valve moves in this
direction while connecting the
battery.
Replacement
NOTE: Throttle valve body/A/T clutch pressure control
solenoid valve must be replaced as an assembly.
1. Check the throttle valve body passages for dust or
dirt, and replace as an assembly, if necessary.
2. Clean the mounting surface and fluid passages of
the throttle valve body.
3. Install the throttle valve body/A/T clutch pressure
control solenoid valve onto the secondary valve
body, and tighten the bolts to the specified torque.
