Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil catch pan, torque wrench, rags
Disconnect the negative battery terminal to reset the engine control unit (ECU).
Allow the engine to cool before starting any inspection.

2. Check and Reset the Check Engine Light

Use the OBD-II scanner to read any stored trouble codes.
Clear the codes from the ECU with the scanner, then reconnect the battery terminal.
Start the engine to see if the check engine light returns.

3. Inspect Oil Level and Quality

Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If the oil is dirty or the level is low, drain the oil and replace it with the correct type and amount.
Sub-steps:
- Place an oil catch pan under the oil pan.
- Remove the drain plug and allow the old oil to fully drain.
- Replace the drain plug and tighten to manufacturer specifications (usually around 30 lb-ft).
- Refill with the appropriate oil type (usually 0W-20 for Honda CR-V).

4. Inspect Oil Filter

Check the oil filter for proper installation; ensure it’s not loose or leaking.
If necessary, replace the oil filter:
- Use an oil filter wrench to remove the old filter.
- Apply a bit of new oil to the rubber gasket of the new filter.
- Install the new filter by hand-tightening it securely.

5. Check for Vacuum Leaks

Inspect hoses connected to the intake manifold for any disconnections or damages.
Use a smoke test if necessary to detect leaks.
