why does my Toyota RAV4 Fifth Generation (2019-present) have excessive fuel consumption

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Air Filter

• Remove the air filter cover using a socket set.
• Take out the old air filter and inspect for dirt and debris.
• Install the new air filter, ensuring it fits snugly, and replace the cover.
• Reconnect the negative battery terminal.

3. Clean or Replace Fuel Injectors

• If cleaning, use a fuel injector cleaning kit; connect it to the fuel rail.
• Follow the kit instructions to clean the injectors.
• If replacing, disconnect the fuel line and electrical connectors for the injectors.
• Remove the old injectors using a socket set, and install new ones, ensuring proper seating and connections.

4. Check and Adjust Tire Pressure

• Use a tire pressure gauge to measure the pressure in all four tires.
• Inflate or deflate tires to the manufacturer-recommended PSI found in the owner's manual or on the driver’s side door jamb.

5. Replace Spark Plugs

• Remove the ignition coil using a socket set.
• Unscrew the old spark plugs using a spark plug socket.
• Install new spark plugs, tightening them to the specified torque (usually around 13-15 lb-ft, check manufacturer specs).
• Reinstall the ignition coils.
