Resetting the check engine light on a Kia Sorento (Third Generation, 2015-2020) involves several steps. However, it’s crucial to understand that simply resetting the light does not address the underlying issue that triggered it. If you haven’t already diagnosed and repaired the issue, it’s advisable to do so to prevent further damage. Below are the detailed steps to both diagnose and reset the check engine light.

Symptoms
  • Check Engine Light (CEL) illuminated on the dashboard.
  • Potentially noticeable engine performance issues (e.g., rough idling, decreased fuel efficiency).
  • Error codes may be present if scanned.
Diagnostic Steps

  1. Obtain an OBD-II Scanner:

    • Tools Required: OBD-II scanner (available at auto parts stores or online).

  2. Connect the OBD-II Scanner:

    • Locate the OBD-II port under the dashboard, typically near the driver’s side, beneath the steering column.
    • Plug the OBD-II scanner into the port.

  3. Read the Diagnostic Trouble Codes (DTCs):

    • Turn on the ignition to the "ON" position without starting the engine.
    • Follow the prompts on the scanner to read the codes stored in the vehicle’s computer.
    • Note down any codes that are present (e.g., P0420, P0300).

  4. Interpret the Codes:

    • Use the scanner’s manual or an online resource to understand what the codes mean.
    • Investigate and address the root cause of the codes before resetting the light.
Repair Instructions
  1. Address the Issue:
    • Based on the DTCs, inspect and repair the relevant components (e.g., replacing faulty sensors, fixing leaks, etc.).
    • After repairs, double-check to ensure everything is functioning correctly.
Resetting the Check Engine Light

If you have resolved the underlying issue, you can reset the check engine light using one of the following methods:

Method 1: Using an OBD-II Scanner

  1. Reconnect the OBD-II Scanner: If you have disconnected it after reading codes, reconnect it.
  2. Turn on Ignition: Set the ignition to the "ON" position without starting the engine.
  3. Select 'Erase Codes' or 'Clear Codes':
    • Navigate through the scanner menu to find the option to erase or clear the trouble codes.
    • Confirm the action, and the check engine light should turn off.

Method 2: Battery Disconnect Method

  1. Turn Off the Engine: Ensure the vehicle is off.
  2. Disconnect the Negative Battery Terminal:
    • Use a wrench (usually 10mm) to loosen the nut on the negative battery terminal.
    • Remove the cable from the terminal and ensure it does not touch the battery.
  3. Wait for 15-30 Minutes: This allows the vehicle’s computer to reset.
  4. Reconnect the Negative Battery Terminal:
    • Reattach the negative battery cable and tighten it securely.
  5. Start the Engine: Check if the check engine light is off.
Conclusion

By following these steps, you can reset the check engine light on your Kia Sorento while ensuring that any underlying issues are properly addressed. Always remember that diagnostics and repairs should be prioritized over simply turning off warning lights.
