my Toyota Tacoma N300 (2016-Present) has a check engine light and no power, what do I do?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, cleaning supplies.
• Disconnect the battery to ensure safety while working on the electrical components.

2. Address Error Codes

• Use the OBD-II scanner to read trouble codes.
• Research the codes to identify potential faulty components (e.g., P0300 for random misfire).

3. Clean or Replace Components

• Air Filter: If the air filter is dirty, remove it and replace it with a new one.

  • Sub-steps:
    1. Open the hood and locate the air filter housing.
    2. Unclip the housing and remove the old filter.
    3. Install the new filter and secure the housing.

• Throttle Body: If there's buildup, clean it using throttle body cleaner.

  • Sub-steps:
    1. Remove the air intake duct connecting to the throttle body.
    2. Spray throttle body cleaner on a cloth and wipe the interior surfaces of the throttle body.
    3. Reattach the intake duct securely.

4. Check and Replace Spark Plugs

• Inspect spark plugs and replace if necessary.
  • Sub-steps:
    1. Remove the ignition coil or spark plug wire.
    2. Use a socket to unscrew the spark plug and inspect for wear.
    3. Install new spark plugs, ensuring they are gapped correctly (typically 0.044 inches for Tacoma).
    4. Torque the spark plugs to manufacturer specification (usually around 13 ft-lbs).

5. Inspect and Repair Fuel System

• Check the fuel pump operation and inspect the fuel filter.
  • Sub-steps:
    1. Access the fuel pump relay and check for proper operation using a multimeter.
    2. Replace the fuel filter if it shows signs of clogging.
