THROTTLE BODY INSPECTION [L8, LF, L3]

id0113z1802600

  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
