how to fix my Toyota Corolla E170 (2013-2019) when it stalls while driving

Solution

1. Preparation

• Ensure you have the necessary tools and parts.
• Disconnect the battery to prevent electrical shorts.
• Allow the engine to cool if it has been running.

2. Addressing Fuel System Issues

• Check Fuel Pump:

  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the ON position (do not start the engine) and check the pressure; it should match the specifications (usually around 40-50 psi).
  • If pressure is low, replace the fuel pump.

• Replace Fuel Filter:

  • Locate the fuel filter (usually near the fuel tank or along the fuel line).
  • Use appropriate wrenches to disconnect the fuel lines.
  • Install the new fuel filter, ensuring correct orientation and secure connections.

3. Inspecting the Ignition System

• Replace Spark Plugs:

  • Remove the spark plug wires carefully.
  • Use a spark plug socket to remove old spark plugs.
  • Install new spark plugs with the recommended gap (usually around 0.043 inches) and torque to manufacturer specifications (about 13 lb-ft).

• Inspect/Replace Ignition Coils:

  • Remove bolts securing the ignition coils.
  • Disconnect the electrical connectors and remove the coils.
  • Install new ignition coils and reconnect the electrical connectors.

4. Cleaning the Throttle Body

• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
• Reinstall the air intake duct securely.

5. Reconnecting and Testing

• Reconnect the battery terminals.
• Start the vehicle and allow it to idle for a few minutes.
• Check for any leaks and ensure that the engine runs smoothly.
