why does my Ford Explorer's engine light come on after changing the oil?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to avoid electrical shorts.

2. Inspect Engine Oil Level

• Sub-steps:
  • Remove the dipstick and wipe it clean.
  • Reinsert the dipstick and remove it again to check the oil level.
  • If the oil is low, add the correct type of oil as specified in the owner's manual.

3. Check Oil Filter Installation

• Sub-steps:
  • Visually inspect the oil filter for proper alignment and any signs of leakage.
  • If the filter is leaking, tighten it to the manufacturer's specifications or replace it.

4. Verify Oil Type and Viscosity

• Sub-steps:
  • Confirm that the oil used is the correct type and viscosity recommended by Ford for the specific Explorer model.
  • If incorrect oil was used, perform an oil change with the correct oil.

5. Check Engine Sensors

• Sub-steps:
  • Inspect the oil pressure sensor connector for any loose wires or disconnection.
  • If necessary, reconnect or replace the oil pressure sensor.

6. Test and Reset Check Engine Light

• Sub-steps:
  • Reconnect the battery after all inspections and repairs.
  • Use the OBD-II scanner to clear the check engine light.
  • Start the engine and monitor for any reoccurrence of the check engine light.

Tools Required:

• OBD-II scanner
• Socket set

• Dipstick

Parts Required:

• Engine oil (correct type and viscosity)

Estimated Repair Time: 1-2 hours

Safety Warnings:
