THROTTLE BODY INSPECTION [L8, LF, L3]

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 throttle actuator terminals E and F.

• If not as specified, replace the throttle body. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].) (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].)

• 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 [L8, LF, L3].)

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

Open circuit

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

- Throttle actuator terminal F and PCM terminal 2A

- Throttle actuator terminal E and PCM terminal 2B

Short circuit

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

- Throttle actuator terminal F and power supply

- Throttle actuator terminal F and GND

- Throttle actuator terminal E and power supply

- Throttle actuator terminal E and GND
