P0016: Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
High SeverityNot safe to driveIgnition
P0016 means the crankshaft and intake camshaft on Bank 1 are not in the correct rotational relationship. The ECU detects that camshaft position deviates from what it commanded based on crankshaft position. Causes range from low oil level to timing chain stretch.
What does P0016 mean?
P0016 means the crankshaft and intake camshaft on Bank 1 are not in the correct rotational relationship. The ECU detects that camshaft position deviates from what it commanded based on crankshaft position. Causes range from low oil level to timing chain stretch.
P0016 is a ignition-related diagnostic trouble code classified as high severity. When your vehicle's ECU detects this condition, it stores P0016 and illuminates the check engine light.
What are the symptoms of P0016?
If your vehicle has triggered P0016, you may notice one or more of these symptoms:
Check engine light illuminated
Rattling or clattering from front of engine on cold start
Rough idle or engine vibration
Reduced power and hesitation
Poor fuel economy
Engine may stall or fail to start in severe cases
What causes P0016?
Here are the most common causes of P0016, ranked by how likely they are to be the culprit:
highDegraded or low engine oil (VVT system relies on oil pressure)
highStretched timing chain (wear at 100,000+ km)
mediumFailed VVT/VCT solenoid (oil control valve)
mediumWorn or failed timing chain tensioner
lowCamshaft or crankshaft position sensor fault
lowTiming chain jumped one or more teeth
Is it safe to drive with P0016?
No - address this immediately. Drive only short distances to reach a shop. If the timing chain is stretched or the tensioner has failed, continued driving risks the chain skipping teeth, which can bend valves and destroy the engine on interference designs. If you hear a cold-start rattle, get it diagnosed immediately.
How do you diagnose P0016?
Follow these steps to pinpoint the root cause of P0016:
Check engine oil level and condition. If low, dirty, or overdue for change, start here. Correct spec oil resolves P0016 in 20-30% of cases
Listen for cold-start rattle from front of engine (1-5 seconds on startup). This is the classic timing chain stretch symptom
Read live data: check camshaft position deviation from commanded position. Deviation over 5-10 degrees indicates timing issue
Test VVT solenoid: check resistance with multimeter, inspect mesh screen for debris. A clogged screen is a common quick fix
If oil change and VVT solenoid check don't resolve, a timing chain kit replacement is likely needed. Have a shop confirm with a timing chain wear measurement
How much does P0016 cost to fix?
Repair costs for P0016 vary depending on the root cause and your vehicle. Here are typical estimates:

P0016 on specific vehicles
P0016 behaves differently depending on your vehicle. Select your car below for model-specific causes, known issues, and adjusted cost estimates:
P0016 on Toyota Camry
Toyota Camry • 2007-2024
The 2AR-FE 2.5L uses a timing chain with a hydraulic VVT-i system. P0016 on this engine is often caused by oil starvation to the VVT actuator from extended oil change intervals. Toyota recommends 0W-20 oil. Using heavier oil or going beyond 10,000 km between changes increases risk. The timing chain itself is robust on this engine and rarely stretches before 200,000 km.

P0016 on Honda Civic
Honda Civic • 2006-2024
The 1.5T (L15B7) in 2016+ Civics uses a VTC actuator that can fail, causing P0016 alongside a loud rattle on cold start. Honda issued TSB 18-074 for VTC actuator noise. The R18A in older Civics uses a simpler timing chain setup and rarely triggers P0016 unless severely neglected on oil changes.

P0016 on Volkswagen Golf
Volkswagen Golf • 2005-2024
The 1.4 TSI (EA111) from 2006-2014 is notorious for timing chain stretch, often as early as 60,000-80,000 km. VW revised the chain design multiple times. The EA888 2.0T is more reliable but can still develop chain issues at 150,000+ km. The tensioner is a known weak point on both engines. Budget for the full chain kit, not just the chain.

P0016 on BMW 3 Series
BMW 3 Series • 2006-2024
The N47 diesel (if applicable) and N20/N26 4-cylinder turbos are known for timing chain issues. The N20 chain is on the transmission side of the engine, requiring engine-out or transmission-out removal for replacement, dramatically increasing labour cost. The N52/N55 inline-6 engines have more robust timing chains but VANOS solenoid failures are common and trigger P0016.

Common questions about P0016
Is P0016 serious?
Yes. It indicates engine timing is off, ranging from a simple oil change fix to a stretched timing chain. If the chain skips teeth on an interference engine, valves can bend, causing catastrophic damage.
Can low oil cause P0016?
Yes. The VVT system uses oil pressure to adjust camshaft position. Low or degraded oil means the actuator can't respond fast enough. An oil change resolves P0016 in 20-30% of cases.
What does cold start rattle mean with P0016?
A 1-5 second rattle from the front of the engine after cold start means the timing chain has slack. Oil pressure hasn't built up yet to tension the chain. This worsens over time.
How much does a timing chain replacement cost?
The chain kit (chain, guides, tensioner) costs 150-600 euros. Labour is 500-2,000 euros because it requires significant engine disassembly. Total: 650-2,600 euros depending on the engine.
