why does my Toyota RAV4 XA40 (2013-2018) have a check engine light after oil change

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is turned off and cool.
• Disconnect the negative battery terminal to avoid any electrical issues while working.

2. Inspect and Tighten Components

• Oil Filter Inspection

  • Remove any plastic cover if necessary to access the oil filter.
  • Inspect the oil filter for proper seating and ensure it is not leaking.
  • If loose, tighten the oil filter according to manufacturer specifications usually found on the filter itself.

• Drain Plug Inspection

  • Locate the oil drain plug and check for any oil leaks.
  • If leaking, use a socket set to tighten the drain plug to the specified torque (usually around 25-30 ft-lbs for Toyota models).

3. Check Oil Level

• Oil Level Adjustment
  • Remove the dipstick and wipe it clean. Reinsert it fully and remove it again to check the oil level.
  • If the oil level is low, add the recommended oil type (typically 0W-20 for the RAV4) until it reaches the full mark.
  • If overfilled, drain excess oil from the drain plug until the correct level is achieved.

4. Reconnect Battery

• Reconnect the negative battery terminal securely.
• Ensure no tools are left in the engine bay.

5. Clear Error Codes

• Use the OBD-II scanner to clear any error codes and reset the check engine light.
