why does my Toyota RAV4 Fifth Generation (2019-present) have poor acceleration

Solution

1. Preparation

• Gather required tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before beginning work.

2. Replace Air Filter

• Remove the air filter cover using a socket set.
• Take out the old air filter and inspect the air intake for dirt or debris.
• Install the new air filter (ensure it fits snugly) and secure the cover.

3. Inspect and Test Throttle Position Sensor (TPS)

• Locate the TPS on the throttle body.
• Disconnect the electrical connector.
• Use a multimeter to test the TPS; ensure it shows a smooth voltage change as the throttle is opened.
• If faulty, replace the TPS with a new unit and reconnect the electrical connector.

4. Test and Replace Fuel Pump if Necessary

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition to the "ON" position without starting the engine to check the pressure.
• If the pressure is below specifications, replace the fuel pump.
• To replace, remove the fuel pump access panel, disconnect the fuel lines, and replace the pump.

5. Replace Ignition Components

• Remove the engine cover if necessary.
• Disconnect the ignition coils and remove the bolts securing them.
• Replace worn spark plugs with new ones and install new ignition coils.
• Reattach all components securely.
