OBD Diagnostics for Crankshaft and Camshaft Position Synchronization

Modern engines rely on precise synchronization between the crankshaft and camshaft. Any deviation can lead to misfires, poor performance, or engine failure. OBD crankshaft and camshaft diagnostics allow early detection of timing-related problems.

Role of Crankshaft and Camshaft Sensors

• Crankshaft sensor tracks piston position

• Camshaft sensor controls valve timing

• ECU compares both signals continuously
