(4)Connect a jumper wire to the positive terminal Number 2 of the injector harness and touch the battery positive post for no longer than 5 seconds.

This releases system pressure.

(5)Remove jumper wires.

(6)Continue fuel system service.

THROTTLE POSITION SENSOR (TPS)

REMOVAL

(1)Disconnect the negative cable from the battery.

(2)Disconnect harness connector from throttle position sensor (Fig. 3).

(3)Remove throttle position sensor mounting screws.

(4)Lift throttle position sensor off throttle shaft.

Fig. 3 Throttle Position Sensor

INSTALLATION

(1)Install throttle position sensor on throttle shaft. Install mounting screws. Tighten screws to 2 Nzm (17 in lbs.) torque.

(2)Attach harness connector to sensor.

(3)Connect negative cable to negative post of the battery.

AUTOMATIC IDLE SPEED (AIS) MOTOR

REMOVAL

(1)Disconnect negative cable from battery.

(2)Disconnect harness connector from AIS (Fig. 4).

(3)Remove AIS motor mounting screws.

(4)Remove the AIS motor from throttle body (make certain that the O-ring is on the AIS motor).

INSTALLATION

(1)New AIS motors have a new O-ring installed on them. If pintle measures more than 1 inch (25

mm)it must be retracted by using the AIS MOTOR OPEN/CLOSE mode of the DRBII (battery must be reconnected for this operation).

(2)Carefully place AIS motor into throttle body.

(3)Install mounting screws. Tighten screws to 2 Nzm (17 in. lbs.) torque.

(4)Connect harness connector to AIS motor.

(5)Connect negative cable to battery.

THROTTLE BODY REMOVAL

(1)Disconnect negative cable from battery.

(2)Remove clamp from air hose. Remove hose (Fig.

5).

(3)Remove accelerator cable.

(4)Disconnect automatic idle speed (AIS) motor and throttle position sensor (TPS) electrical connectors (Fig. 6).

(5)Disconnect vacuum hoses from throttle body.

(6)Remove throttle body to intake manifold attaching nuts (2).

(7)Remove throttle body and gasket.
