Electronic Throttle Actuator: Testing and Inspection

THROTTLE ACTUATOR INSPECTION[L3]

NOTE: Perform the following inspection only when directed.

Resistance Inspection
1. Disconnect the negative battery cable.
2. Disconnect the throttle body connector.

Specification:

3. Measure the resistance between the throttle actuator terminals using an ohmmeter.
- If not as specified, replace the throttle body.
- If as specified, carry out the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection
1. Disconnect the PCM connector.




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

Open circuit
- If there is no continuity, there is an open circuit. Repair or replace the harness.
- Throttle actuator terminal F and PCM terminal 2A
- Throttle actuator terminal E and PCM terminal 2B

Short circuit
- If there is continuity, there is a short circuit. Repair or replace the 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
