P0024 – Exhaust Camshaft Position Timing Over-Advanced or System Performance (Bank 2)

P0024 – Exhaust Camshaft Position Timing Over-Advanced or System Performance (Bank 2)

The P0024 diagnostic trouble code (DTC) indicates that the Engine Control Module (ECM) has detected that the exhaust camshaft timing on Bank 2 is more advanced than expected. This problem is commonly related to the Variable Valve Timing (VVT) system, engine oil issues, or incorrect valve timing.

Symptoms of P0024

• Check Engine Light illuminated.
• Rough idle.
• Reduced engine power.
• Poor acceleration.
• Increased fuel consumption.
• Engine hesitation or stalling.
• Possible engine rattling noise.

Common Causes

• Dirty or low engine oil.
• Incorrect engine oil viscosity.
• Faulty VVT oil control valve (OCV).
• Stuck camshaft phaser.
• Stretched timing chain or worn timing components.
• Faulty camshaft position sensor.
• Damaged wiring or poor electrical connections.
• Engine mechanical timing out of specification.

How to Diagnose P0024

1. Check the engine oil level and condition.
2. Verify the correct oil viscosity is being used.
3. Scan for additional trouble codes.
4. Inspect the VVT oil control valve and wiring.
5. Monitor camshaft timing using a scan tool.
6. Inspect the timing chain and timing marks.
7. Test the camshaft position sensor if necessary.

Possible Repairs

• Replace engine oil and oil filter.
• Replace the VVT oil control valve.
• Repair damaged wiring or connectors.
• Replace a faulty camshaft position sensor.
• Replace the timing chain and related components if worn.
• Repair incorrect mechanical engine timing.

Can You Drive With Code P0024?

Driving with code P0024 is not recommended. If ignored, improper camshaft timing can reduce engine performance, increase fuel consumption, and eventually lead to severe engine damage.

Estimated Repair Cost

• Oil and filter change: $30–$100
• VVT oil control valve replacement: $100–$350
• Camshaft position sensor replacement: $50–$250
• Timing chain replacement: $600–$2,500
