Different Ways To Get Check Engine Light Codes

When your Toyota’s check engine light comes on, it’s essential to determine the underlying issue promptly. Here are some methods to retrieve check engine light codes without a scanner.

The trip meter method involves a simple sequence of steps to access check engine light codes on your Toyota. First, ensure your ignition key is in the off position.

  1. Press and hold the trip meter reset button.
  2. Turn the ignition key to the on position without starting the engine. Keep holding the reset button until the trip meter reads “000000.”
  3. Release the reset button, and the check engine light will start flashing the codes in a series of short and long pulses.

The paperclip or wire method is another DIY approach to extracting check engine light codes. You will need a small piece of wire or a paperclip for this method.

  1. Locate your Toyota’s diagnostic connector under the dashboard near the driver’s side.
  2. Insert the paperclip or wire into the terminals TE1 and E1 to jump-start the diagnostic system.
  3. Observe the check engine light flashes to decode the fault codes, where a series of long and short pulses represent different numbers.

If your Toyota is an older model manufactured before 1996, you can utilize an OBD-I scanner tool to read the check engine light codes. This method provides more accurate results.

  1. Locate the diagnostic connector under the hood or dashboard, depending on your Toyota’s model year.
  2. Connect the OBD-I scanner tool and turn the ignition key to the on position to retrieve the error codes.
  3. Refer to the scanner’s manual to interpret the specific codes for troubleshooting your Toyota effectively.
