Throttle Actuator Inspection
THROTTLE ACTUATOR INSPECTIONNOTE: 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
- 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 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
