why is my Toyota RAV4 XA40 (2013-2018) stalling while driving

Solution

1. Preparation

• Gather tools and parts; ensure vehicle is parked on a level surface.
• Disconnect the negative battery cable to avoid electrical shocks.
• Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, throttle body cleaner.

2. Address Fuel System Issues

2.1. Fuel Pump Test

• Connect the fuel pressure gauge to the fuel rail test port.
• Turn the ignition to the "ON" position without starting the engine to check pressure.
• Ensure pressure meets the specifications (typically around 50-60 psi).
• If pressure is low, replace the fuel pump.

2.2. Fuel Filter Replacement

• Locate and remove the fuel filter using a socket set.
• Replace with a new fuel filter, ensuring correct orientation and tight connections.

3. Inspect and Replace Ignition Components

3.1. Spark Plug and Ignition Coil Inspection

• Remove the ignition coils using the socket set.
• Inspect spark plugs for wear or deposits; replace if necessary.
• Replace ignition coils if they show signs of damage or wear.

4. Clean the Throttle Body

• Remove the air intake duct connected to the throttle body.
• Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
• Wipe clean with a lint-free cloth to remove carbon buildup.

5. Reassemble and Final Checks

• Reconnect all components removed during the repair.
• Reconnect the negative battery cable.
• Clear any error codes using the OBD-II scanner.
