why does my Toyota RAV4 XA40 (2013-2018) feel like it's losing power going uphill

Solution

1. Preparation

• Gather the necessary tools and parts, ensuring the vehicle is parked on a level surface.
• Disconnect the negative terminal of the battery to ensure safety.

2. Address Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the old air filter and inspect it for dirt and damage.
• Replace with a new air filter if necessary.
• Reassemble the air filter housing cover securely.

3. Fuel System Inspection

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition key to the "on" position (do not start) and check the pressure reading against manufacturer specifications.
• If pressure is low, inspect the fuel pump and fuel filter for potential replacement.

4. Exhaust System Check

• Inspect the exhaust system visually for any signs of damage or blockages.
• If a clogged catalytic converter is suspected, use a back pressure gauge to confirm.
• Replace the catalytic converter if the back pressure is above the acceptable limit.

5. Throttle Position Sensor (TPS) Testing

• Locate the TPS on the throttle body and disconnect the electrical connector.
• Use a multimeter to check the voltage output at the TPS while moving the throttle.
• Replace the TPS if the readings are outside of the manufacturer's specified range.

6. Transmission Fluid Inspection

• Remove the transmission dipstick and check the fluid level and color.
• If low, add the appropriate type of transmission fluid as specified in the owner's manual.
• If the fluid smells burnt or appears dark, consider a transmission fluid change.
