Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify camshaft-related issues.
2
Inspect engine oil level and condition, as low or dirty oil can affect camshaft performance.
3
Perform a visual inspection of the camshaft for signs of wear or damage.
4
Check the timing chain/belt for proper alignment and tension.
5
Measure camshaft lift and duration using a dial gauge if accessible.
