Symptoms
  • Check engine light illuminated
  • Possible oil leak noted under the vehicle
  • Engine running rough or with reduced performance
  • Increased engine noise or knocking
  • Oil pressure warning light may also be illuminated
Diagnostic Steps
  1. Scan the vehicle's OBD-II system for error codes using an OBD-II scanner.
  2. Check the engine oil level and condition to ensure it is within the recommended range and not contaminated.
  3. Inspect the oil filter and drain plug for leaks or improper installation.
  4. Verify that the correct oil type and viscosity were used during the oil change.
  5. Reset the check engine light and monitor if it reappears during a test drive.
Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Correct Oil Change Components

  • Oil Filter Inspection:

    • Remove the oil filter using an oil filter wrench.
    • Check the rubber O-ring for damage or debris.
    • If the filter was not installed properly, install a new filter, ensuring the O-ring is lubricated with fresh oil and seated correctly.

  • Drain Plug Inspection:

    • Recheck the drain plug for correct torque (typically 25-30 ft-lbs).
    • If leaking, replace the washer and re-torque the plug.
3. Check Engine Oil Level
  • Refill if necessary with the correct type of oil (API SN or higher, SAE 0W-20 or 5W-30 as specified).
  • Start the engine and let it idle for a few minutes to circulate the oil, then turn off the engine and recheck the oil level.
4. Clear Error Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to reset the check engine light.
  • Perform a test drive to ensure the light does not reappear.
