Code P0016 reports that the camshaft position does not match the crankshaft position: it is a timing problem. It must always be taken seriously, because it may involve the timing chain or belt.
What code P0016 means
Crankshaft/camshaft position correlation (bank 1, sensor A).
Typical symptoms
- Check engine light on
- Hard starting or no start
- Loss of power and rough idle
- Chain noise or unusual rattling
- Higher fuel consumption
Most likely causes
| Cause | How common | What to do |
|---|---|---|
| Stretched or mistimed timing chain or belt | Common | Check timing and replace the kit |
| Variable timing actuator or control solenoid | Common | Test and replace |
| Dirty oil, low level or wrong viscosity | Common | Change oil and filter with the correct spec |
| Camshaft or crankshaft sensor | Less common | Check the signal and replace |
| Worn chain tensioner | Less common | Replace |
How it is diagnosed
- Check oil level and condition.
- Read live timing (actual versus requested).
- Test solenoids and sensors.
- Mechanical check of chain or belt.
Can you drive with code P0016?
Better not: out-of-time valve timing can damage valves and pistons. If it appears together with noises or starting problems, stop and have it checked.
How much does it cost to fix?
| Work | Indicative cost |
|---|---|
| Oil and filter change | €80-200 |
| Variable timing solenoid | €100-300 |
| Camshaft sensor | €60-200 |
| Chain or belt kit with pump | €500-1,500 and over |
Figures are indicative market ranges, useful for orientation: the real cost depends on model, engine, parts chosen and labour hours. For an exact quote we need the vehicle registration number.
How MasterTuning helps
We read the real values of the control unit, not just the code: that is the difference between finding the faulty component and replacing parts by trial and error. After the repair we clear the error and check that it does not come back. Find the nearest centre or contact us.

Frequently asked questions
What does P0016 mean?
That camshaft and crankshaft timing is not correct, on bank 1.
Is it serious?
It can be: with a stretched or out-of-time chain valves and pistons may be damaged. It must be diagnosed soon.
Can an oil change fix it?
Sometimes yes, if the variable timing actuator was affected by dirty oil or a low level; but it has to be verified.
How much does it cost to fix P0016?
From €100-300 for a solenoid to €500-1,500 and over for the timing kit.
