THROTTLE ACTUATOR INSPECTION [L3 Turbo]

id0113b5801300

  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
