why is my Toyota Camry XV40 (2007-2011) losing power when I accelerate

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Clean Air Intake

• Remove the air intake duct by loosening the clamps and disconnecting any sensors.
• Inspect the air filter; replace if dirty.
• Clean the throttle body with throttle body cleaner and a soft brush.
• Reinstall the air intake duct and reconnect sensors.

3. Check Fuel System

• Connect the fuel pressure gauge to the fuel rail test port.
• Turn the ignition to the “ON” position (do not start the engine) and check the pressure.
  • Ensure it meets manufacturer specifications (typically around 30-40 psi for the Camry).
• If pressure is low, inspect the fuel pump and fuel filter; replace if necessary.

4. Inspect Ignition System

• Remove the spark plugs using a spark plug socket.
• Inspect spark plugs for wear or deposits; replace if needed.
• Test ignition coils with a multimeter; replace any that are out of specification.

5. Check Transmission Fluid

• Locate the transmission dipstick, remove it, and check the fluid level.
• If low, add the correct type of transmission fluid (typically Toyota ATF WS).
• If fluid is burnt or dirty, consider a transmission fluid change.
