how to fix the throttle response issue in my Honda Accord Eleventh Generation (2023-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle battery to ensure safety during repairs.
• Allow the engine to cool if it has been running.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, soft cloth, socket set.
• Remove the air intake duct connected to the throttle body.
• Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
• Wipe clean with a soft cloth to remove any buildup.
• Reattach the air intake duct securely.

3. Inspect and Replace the Throttle Position Sensor (if faulty)

• Tools Required: Multimeter, socket set, torque wrench.
• Locate the throttle position sensor on the throttle body.
• Unplug the electrical connector and remove the mounting bolts.
• Measure the voltage output using a multimeter; it should vary smoothly as the throttle is opened.
• If readings are outside specified parameters, replace the sensor with a new one.
• Reinstall the sensor and tighten bolts to manufacturer specifications.

4. Test the Accelerator Pedal Position Sensor

• Tools Required: Multimeter.
• Locate the accelerator pedal position sensor under the dashboard.
• Disconnect the electrical connector and test the voltage output at idle and full throttle.
• If readings are inconsistent or out of range, replace the sensor.

5. Reconnect Battery and Clear Codes

• Reconnect the vehicle battery terminals securely.
• Use the OBD-II scanner to clear any trouble codes that may have been generated.
