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 prevent accidental short circuits.

2. Inspect and Replace Timing Components

Inspect Timing Belt/Chain:
- Remove any covers blocking access to the timing belt/chain using a socket set.
- Check for cracks, fraying, or signs of stretching.
- If damaged, proceed to the next step.
Replace Timing Belt/Chain (if necessary):
- Use a torque wrench to remove the tensioner and pulleys.
- Align timing marks on the crankshaft and camshaft.
- Install the new timing belt/chain, ensuring proper tension as per manufacturer specifications.
- Reattach all components and covers using the correct torque values.

3. Sensor Replacement

Replace Camshaft and Crankshaft Sensors (if faulty):
- Disconnect the electrical connectors from the sensors.
- Remove the sensors using a socket set.
- Install the new sensors, ensuring they are seated properly.
- Reconnect the electrical connectors.

4. Reassemble and Reconnect

Reinstall any covers and components removed during disassembly.
Reconnect the battery.
Ensure all tools are removed from the engine bay.
