Electronic Throttle Actuator Relay Repair Procedures
Diagnosis
Before beginning any repair, confirm the electronic throttle actuator relay is faulty through these steps:
- Scan for diagnostic trouble codes (DTCs)
- Check for power at the relay terminals
- Listen for clicking sound when relay is energized
- Inspect for visible damage or corrosion
Basic Relay Replacement
Step 1:Locate the electronic throttle actuator relay
- Usually found in the main fuse/relay box under the hood
- Consult vehicle manual for exact location
Step 2:Remove the old relay
- Disconnect the negative battery terminal
- Remove any covers or panels protecting the relay box
- Carefully pull the old relay straight out of its socket
Step 3:Install new relay
- Verify the new relay matches the specifications of the original
- Insert the new relay into the socket, ensuring proper orientation
- Press firmly until seated
Step 4:Test the repair
- Reconnect the battery
- Start the vehicle and verify proper throttle operation
- Clear any stored DTCs
- Test drive to confirm fix
Advanced Repair (Circuit Issues)
If problems persist after relay replacement:
- Check wiring harness for damage or corrosion
- Test circuit continuity
- Inspect connector terminals
- Verify proper voltage at all relay terminals
Note: Some vehicles may require programming or adaptation procedures after relay replacement. Consult manufacturer specifications for your specific model.
Important Safety Notice:Always follow proper safety procedures when working with electrical components. If unsure, consult a professional technician.

Common Signs of Electronic Throttle Actuator Relay Failure
Check Engine Light
One of the first indicators of a failing throttle actuator relay is an illuminated check engine light. The vehicle's computer system will detect irregular voltage or performance issues and trigger this warning.
Inconsistent Idle
When the relay begins to fail, you may notice:
- Rough or unstable idle
- Engine RPMs fluctuating without input
- Stalling at stoplight or when stationary
Acceleration Issues
A faulty relay can cause:
- Delayed throttle response
- Sudden acceleration surges
- Hesitation when pressing the gas pedal
Starting Problems
The vehicle may:
- Have difficulty starting
- Require multiple attempts to start
- Exhibit a delayed start
Maintenance Schedule
Regular Inspection
While there's no specific replacement interval for the electronic throttle actuator relay, it should be inspected:
- During routine maintenance (every 30,000 miles)
- When performing diagnostic tests
- If any of the above symptoms occur
Preventative Maintenance
To maximize relay life:
- Keep electrical connections clean and free from corrosion
- Protect from excessive moisture and heat
- Address check engine lights promptly
- Consider replacement around 100,000 miles if experiencing issues
Note: Specific maintenance intervals may vary by vehicle make and model. Consult your vehicle's manual or speak with our certified technicians for model-specific guidance.
