what does it mean when my Toyota Camry XV70 (2018-2024) engine light blinks

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal for safety.

2. Scan and Identify Codes

• Use an OBD-II scanner to retrieve and document any stored trouble codes.
• Analyze the codes to pinpoint the specific malfunction (e.g., P0300 for random misfire, P0171 for lean condition).

3. Inspect Ignition Components

• Remove the engine cover if applicable.
• Check each spark plug for wear or damage; replace if needed (Torque: 13 lb-ft).
• Inspect ignition coils for cracks or sign of arcing; replace faulty coils.
• Reconnect all electrical connections securely.

4. Test the Fuel System

• Connect a fuel pressure gauge to the fuel rail to check pressure (specification: typically 30-40 psi for Camry).
• If pressure is low, inspect the fuel pump, filter, and injectors for proper operation.
• Clean or replace fuel injectors if clogged.

5. Inspect Air Intake and Vacuum Lines

• Remove the air intake duct and visually inspect the air filter; replace if dirty.
• Check for any cracks or loose fittings in the intake hoses.
• Inspect vacuum hoses for leaks; replace any damaged hoses.

6. Examine Exhaust System

• Visually inspect the exhaust system for any obvious signs of leaks or damage.
• Use a smoke test if necessary to locate hidden leaks in the exhaust.
