Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, compression tester, and safety goggles.
Disconnect the battery before working on any electrical components.

2. Remove Engine Cover

Use a socket set to remove bolts securing the engine cover.
Carefully lift off the cover and set it aside, ensuring no debris falls into the engine.

3. Inspect Camshaft and Components

Visually inspect the camshaft for wear, scoring, or damage.
Check the camshaft position sensor and electrical connectors for corrosion or damage.
If damaged, remove the camshaft sensor by unscrewing the retaining screws and gently pulling it out.

4. Replace Camshaft (if necessary)

If the camshaft is determined to be defective, remove the timing belt/chain as per the manufacturer's specifications, noting the torque values for reinstallation.
Remove the camshaft bearing caps and carefully lift out the camshaft.
Install the new camshaft, ensuring it is properly aligned and seated.
Reinstall the bearing caps with the correct torque specifications.

5. Reassemble Engine Components

Reinstall the timing belt/chain, ensuring correct alignment.
Reattach the camshaft position sensor and any other components removed.
Replace the engine cover and secure it with bolts.

6. Final Checks

Reconnect the battery and ensure all electrical connections are secure.
Start the engine and listen for unusual noises, checking for any leaks.
