REPLACEMENT OF THE ENGINE THROTTLE ACTUATOR
Removal:

See Figure 5.
Loosen the actuator throttle cable Anchor Hardware
(A)
and also loosen the wire cable end connection Screw
(B)
as shown.
2 Remove the P-clamp
(C)
at the radiator shroud that is used to route the cable.
3 Note the location of the actuator wiring harness wire connections at the bottom of the Actuator Control Module
(D)
for correct reassembly, then
remove the wiring (see Figure 6).
4 Remove the (4) hex head Screws
(E)
that secure the actuator at its mounting plate and complete the removal of the actuator/cable assembly
from the engine.
Installation:
Follow the above removal steps in reverse to install the new actuator.
Actuator Throttle Speed Adjustment:
Start the engine and run engine to its normal operating temperature. Use a digital tachometer to check and set the correct engine idle and high speed
running specification. Place the tachometer target tape onto the engine crankshaft pulley and aim the meter to pick up the crankshaft speed.
WARNING!
When checking the engine RPM do not allow any loose clothing, hands, tools or test instrument to make contact with the moving engine
fan, pulleys and belt.
Reference Figure 5 that shows the Idle Adjustment Screw
(F)
. The 3 cylinder Exterra’s engine idle speed is to be set at 1500 RPM + or – 20 RPM.
Adjust to the correct speed using a small Phillips screwdriver.
To set the high speed setting first loosen the Lock Nut
(G)
as shown at the actuator then turn the large adjustment sleeve in or out to 2800 RPM +
or – 20RPM. Turn the nut CCW to increase the RPM and CW to lower the RPM. Double check both speeds to confirm the correct settings then
tighten the lock nut at the actuator. Note also check the other end of the cable Wire Screw
(B)
that it is tight, preventing the cable from loosening
and slipping out of adjustment.
