my Toyota RAV4 Fifth Generation (2019-present) is losing power going uphill what's wrong

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and set the parking brake.
• Gather necessary tools and parts, and wear safety gloves.

2. Fuel System Inspection

• Tools Required: Fuel pressure gauge, wrench set
• Sub-steps:
  1. Locate the fuel rail and attach the fuel pressure gauge.
  2. Turn the ignition to the "ON" position (not starting) and check the fuel pressure.
     • Compare the reading to manufacturer specifications (typically around 50-60 psi).
  3. If pressure is low, check the fuel pump and fuel filter for blockages or failures.
  4. Replace the fuel filter if necessary; consider testing or replacing the fuel pump.

3. Air Intake System Inspection

• Tools Required: Screwdriver set, vacuum gauge
• Sub-steps:
  1. Remove the air intake duct and inspect the air filter for dirt and debris.
  2. Replace the air filter if it is clogged.
  3. Inspect the intake manifold for vacuum leaks using a vacuum gauge to check for proper levels.
  4. Tighten or replace any damaged hoses or connections.

4. Exhaust System Check

• Tools Required: Wrench set, jack and jack stands
• Sub-steps:
  1. Lift the vehicle securely using a jack and jack stands.
  2. Inspect the catalytic converter for signs of blockage or damage.
  3. If blockage is suspected, perform a backpressure test using a pressure gauge.
  4. Replace the catalytic converter if backpressure is above acceptable limits (usually over 1.5 psi at idle).

5. Ignition System Check

• Tools Required: Multimeter
• Sub-steps:
  1. Remove the spark plug wires and check for visible damage or corrosion.
  2. Test each ignition coil with a multimeter for proper resistance (refer to specifications).
  3. Replace any faulty ignition components, including spark plugs, wires, or coils.

6. Transmission Functionality

• Tools Required: OBD-II scanner
• Sub-steps:
  1. Check transmission fluid level and condition (should be pink/red and not burnt).
  2. If fluid is low, top it up with the recommended ATF type.
  3. Scan for transmission-related error codes and address any issues found.
