my Honda Pilot YF3 (2016-2022) has an unusual delay in throttle response, what is the issue?

Solution

1. Preparation

• Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent any electrical shorts during the repair.

2. Throttle Body Cleaning

• Remove Throttle Body:

  • Disconnect the electrical connectors from the throttle body.
  • Remove the intake ducting connected to the throttle body using a socket set.
  • Unbolt the throttle body from the intake manifold (typically 4 bolts).

• Clean Throttle Body:

  • Use throttle body cleaner and a soft cloth to clean the throttle plate and bore. Avoid using abrasive materials.
  • Inspect the throttle plate for proper operation; it should move freely without sticking.

• Reinstall Throttle Body:

  • Reattach the throttle body to the intake manifold and tighten bolts to manufacturer’s torque specifications (typically around 16-20 ft-lbs).
  • Reconnect the intake ducting and electrical connectors.

3. Accelerator Pedal Position Sensor Check

• Remove and Inspect Sensor:

  • Locate the accelerator pedal position sensor, usually mounted near the pedal assembly.
  • Disconnect the electrical connector and unbolt the sensor.

• Test Sensor:

  • Use a multimeter to check the resistance across the sensor terminals while slowly pressing the accelerator pedal. Compare readings to manufacturer specifications.

• Replace if Necessary:

  • If readings are outside specifications, replace the sensor with a new one and secure it in place.
