What does this fault code mean?

This code concerns the camshaft position during catalyst warm-up after a cold start, on bank 1. It is set when the camshaft angle is less than requested. Poor engine oil, low oil pressure, or a fault in the control valve or the VVT unit may be behind it.

Possible causes

Poor engine oil quality
Low oil pressure
Damaged camshaft control valve
Damaged VVT unit

What you can do

1If a fault code for the correlation between crankshaft and camshaft position is stored, diagnose it first. Contaminants in the oil can damage the VVT unit
2Check that the engine oil is clean and of the right quality
3If you have a diagnostic tool, read the camshaft position in live data while the car is running steadily and check that it follows the requested position
4Clear the code and road test the car to see whether it returns
5If the code returns, have a workshop with diagnostic equipment check the camshaft control valve and the VVT unit

Symptoms you may notice5

Uneven idle
Reduced performance
The eco lamp is on
The check engine lamp lights or behaves abnormally
The car hesitates or surges, or runs unevenly
