THROTTLE ACTUATOR INSPECTION [L3 Turbo]

Note

• Perform the following inspection only when directed.

Resistance Inspection

1. Disconnect the negative battery cable.

2. Disconnect the throttle body connector.

3. Measure the resistance between the throttle actuator terminals using a tester.

• If not as specified, replace the throttle body. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)

• If as specified, carry out the "Circuit Open/Short Inspection".

Specification

Ambient temperature (°C {°F})	Resistance (ohm)
Approx. 20 {68}	0.3-100

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)

2. Inspect the following wiring harnesses for an open or short circuit (continuity check).

Open circuit

• If there is no continuity, there is an open circuit. Repair or replace the wiring harness.

- Throttle actuator terminal F and PCM terminal 4Y

- Throttle actuator terminal E and PCM terminal 4AB

Short circuit

• If there is continuity, there is a short circuit. Repair or replace the wiring harness.

- Throttle actuator terminal F and power supply

- Throttle actuator terminal F and ground

- Throttle actuator terminal E and power supply

- Throttle actuator terminal E and ground
