my Toyota RAV4 Fifth Generation (2019-present) feels like it's losing power while driving

Solution

1. Preparation

• Gather necessary tools and safety equipment.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Air Filter

• Locate the air filter housing.
• Remove the screws or clips securing the housing.
• Take out the old air filter and inspect it for dirt or blockages.
• Install a new air filter, ensuring it fits snugly in place.
• Reassemble the air filter housing and secure it with screws or clips.

3. Fuel System Inspection

• Attach a fuel pressure gauge to the fuel rail test port.
• Start the engine and observe the fuel pressure reading; it should match the manufacturer's specifications.
• If pressure is low, inspect the fuel pump and fuel filter for clogs or failure.
• Replace the fuel filter if necessary and consider testing or replacing the fuel pump.

4. Ignition System Check

• Remove the spark plug wires and inspect the spark plugs for wear.
• Replace any worn spark plugs with OEM or equivalent parts.
• Test ignition coils with a multimeter; replace any faulty coils.

5. Throttle Position Sensor Replacement

• Locate the TPS on the throttle body.
• Disconnect the electrical connector.
• Remove the screws securing the TPS and carefully remove it.
• Install the new TPS in the same position and secure it with screws.
• Reconnect the electrical connector.

6. Reassemble and Test

• Reconnect the battery.
• Start the engine and allow it to idle.
• Take the vehicle for a test drive to ensure the power loss issue is resolved.
