Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect Throttle Position Sensor (TPS)
  • Locate the TPS on the throttle body.
  • Disconnect the electrical connector from the TPS.
  • Use a multimeter to check the resistance values according to the specifications in the service manual.
    • If the TPS is faulty, replace it with a new unit.
3. Check Accelerator Pedal Assembly
  • Remove the screws securing the accelerator pedal assembly.
  • Disconnect the electrical connector from the pedal.
  • Inspect for any physical damage or wear and tear.
    • If damaged, replace the accelerator pedal assembly.
4. Fuel System Check
  • Connect a fuel pressure gauge to the fuel rail service port.
  • Turn the ignition to the "ON" position without starting the engine to check the fuel pressure.
    • Compare the reading with the manufacturer’s specifications.
    • If pressure is low, inspect the fuel pump and fuel filter for blockages or failure.
5. Transmission Fluid Inspection
  • Check the transmission fluid level using the dipstick while the engine is running.
  • If the fluid is low, add the recommended transmission fluid type.
  • If the fluid is discolored or has a burnt smell, consider a complete fluid change and filter replacement.
