why is my Toyota RAV4 XA50 (2019-2024) losing power going uphill

Solution

1. Preparation

• Gather tools and parts required.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Air Intake

• Remove the air filter and inspect it for dirt and debris.
  • If dirty, replace with a new OEM air filter.
• Check the intake ducts for blockages.
• Clean any dirt from the throttle body using throttle body cleaner and a soft cloth.

3. Fuel System Service

• Attach a fuel pressure gauge to the fuel rail.
• Start the engine and monitor the pressure.
  • If pressure is below specification, consider replacing the fuel pump.
• Inspect and replace the fuel filter if it hasn't been changed recently.

4. Transmission Check

• Locate the transmission dipstick (if applicable) and check the fluid level.
  • If low, add the correct type of fluid as specified in the owner's manual.
• If the fluid is dirty or burnt, perform a transmission fluid change.

5. Throttle Position Sensor (TPS) Replacement

• Disconnect the electrical connector from the TPS.
• Remove the TPS mounting screws and replace it with a new unit.
• Reconnect the electrical connector and ensure it clicks securely.

6. Exhaust System Inspection

• Check for any visible signs of damage or blockages in the exhaust system.
• If necessary, replace damaged components such as catalytic converters or mufflers.
