Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Clean the Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reinstall the air intake duct securely.
3. Inspect and Replace the Air Filter
  • Open the air filter housing and remove the old air filter.
  • Inspect for dirt and debris.
  • Replace with a new air filter that meets manufacturer specifications.
  • Close the air filter housing securely.
4. Check Fuel System
  • Attach a fuel pressure gauge to the fuel rail test port.
  • Start the engine and monitor the fuel pressure; it should meet manufacturer specifications (typically around 50-60 psi).
  • If pressure is low, check the fuel pump and fuel filter for issues.
5. Inspect the Accelerator Pedal Position Sensor
  • Locate the accelerator pedal and disconnect the electrical connector.
  • Use a multimeter to measure the voltage output while pressing the pedal; it should vary smoothly from idle to full throttle.
  • If readings are inconsistent or out of range, replace the accelerator pedal position sensor.
6. Transmission Fluid Check
  • With the engine running, check the transmission fluid level using the dipstick.
  • If fluid is low, add the correct type of transmission fluid (typically ATF WS for Toyota).
  • If the fluid is burnt or discolored, consider a transmission fluid change.
