Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the battery to ensure safety while working on electrical components.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, microfiber cloth, socket set.
• Sub-steps:
  1. Remove the air intake duct connected to the throttle body by loosening the clamps and disconnecting any electrical connectors.
  2. Use the throttle body cleaner to spray the inside of the throttle body while moving the throttle valve open and closed.
  3. Wipe the interior surfaces with a microfiber cloth until free of carbon deposits.
  4. Reconnect the air intake duct and ensure all clamps and connectors are secure.

3. Test and Replace Throttle Position Sensor (if needed)

• Tools Required: Multimeter, socket set.
• Sub-steps:
  1. Locate the throttle position sensor on the throttle body.
  2. Disconnect the electrical connector from the TPS.
  3. Use a multimeter to measure the resistance across the sensor terminals as you manually open the throttle.
  4. Compare the readings to the specifications in the service manual. If readings are out of spec, replace the sensor.
  5. If replacing the TPS, remove the old sensor using a socket and install the new one. Torque to manufacturer specifications.

4. Check and Replace the Accelerator Pedal Position Sensor (if needed)

• Tools Required: Socket set.
• Sub-steps:
  1. Locate the accelerator pedal position sensor near the accelerator pedal assembly.
  2. Disconnect the electrical connector.
  3. Inspect the sensor for any physical damage or corrosion.
  4. If faulty, remove the sensor using a socket and install the new unit. Ensure it is aligned properly before securing.
