- Comments Off on P0016: meaning, causes and solutions
Fault code P0016 means incorrect correlation between crankshaft and camshaft. The ECU detects that the camshaft position does not match the expected one relative to the crankshaft.
Typical symptoms
- Long or impossible starting
- Loss of power
- Rough engine
- Metallic noise when cold on chain engines
Most common causes
- Stretched timing chain or faulty tensioner
- Belt jumped one tooth
- Phase variator stuck by deposits
- Clogged variator solenoid valve
- Damaged camshaft sensor or reluctor ring
How it is checked in diagnosis
- Reading the actual and requested phase angles
- Checking the timing with the locking tools
- Checking oil pressure and quality (variators live on it)
Can you drive with code P0016?
Better not: if the timing is really out of phase the risk of mechanical damage is high.
How MasterTuning helps
We read the real values from the ECU, not just the code: that is the difference between identifying the component responsible and replacing parts by trial and error. After the repair we clear the fault and check that it does not come back. Centres throughout Italy.

Frequently asked questions
What does fault code P0016 mean?
Code P0016 means incorrect correlation between crankshaft and camshaft. The ECU detects that the camshaft position does not match the expected one relative to the crankshaft.
Can you drive with fault P0016?
Better not: if the timing is really out of phase the risk of mechanical damage is high.
Is clearing code P0016 enough to fix it?
No: if the cause is still present the code comes back after a few kilometres. Clearing should only be done after the repair, with the diagnostic tool.
How much does it cost to fix code P0016?
It depends on the component responsible: the diagnosis is precisely what identifies it with real measurements, avoiding unnecessary replacements that cost far more than the correct repair.
