why does my Honda Accord have a check engine light on after oil change

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to clear any stored error codes.

2. Inspect and Verify Oil Change

• Recheck the oil level using the dipstick.
  • If low, add the correct type and amount of oil (check owner's manual for specifications).
• Inspect the oil filter:
  • Remove the oil filter if it is found to be leaking.
  • Replace it with a new filter if necessary, ensuring to lubricate the gasket with new oil before installation.
• Tighten the oil drain plug to the manufacturer's specified torque (typically around 20-25 ft-lbs for most Honda models).

3. Check Engine Components

• Reconnect any disconnected sensors or wiring.
• Visually inspect the engine for any obvious signs of oil leaks or damage.
• Reconnect the negative battery terminal and clear any error codes with the OBD-II scanner.
