Solution
1. Preparation
  • Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the battery to avoid any electrical shorts during the repair.
2. Throttle Cable Inspection
  • Locate the throttle cable connected to the throttle body.
  • Inspect for fraying, kinks, or binding. If damaged, replace the throttle cable.
  • Make sure the throttle plate operates smoothly and closes fully when released.
3. Fuel Pressure Check
  • Connect the fuel pressure gauge to the fuel rail.
  • Turn the ignition key to the "On" position without starting the engine and check the pressure reading.
  • Compare the reading to the manufacturer's specifications (typically around 30-50 PSI for most RAV4 models).
  • If the pressure is low, check the fuel pump and filter for issues.
4. Air Intake System Inspection
  • Inspect the air filter for cleanliness and replace if dirty.
  • Check for any visible cracks or leaks in the intake hoses leading to the throttle body.
  • Ensure the MAF sensor connector is secure and clean the sensor with MAF cleaner if necessary.
5. Transmission Fluid Check
  • Locate the transmission dipstick (if applicable) and check the fluid level and condition.
  • If the fluid is low, add the recommended type of transmission fluid.
  • If the fluid appears dirty or burnt, consider performing a transmission fluid change.
