P0016 — Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A)
Category: Powertrain Severity: High
Updated:
DTC code P0016 means: Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A). It falls under the "Powertrain" category, with an estimated severity of High. Common causes include stretched or jumped timing chain/belt, faulty timing tensioner and failed crankshaft or camshaft sensor; it's worth confirming the diagnosis before replacing parts.
Possible causes
- Stretched or jumped timing chain/belt
- Faulty timing tensioner
- Failed crankshaft or camshaft sensor
- Damaged reluctor wheel
- Sticking VVT solenoid
Symptoms
- Hard start or no start
- Timing chain noise
- Loss of power
- Rough idle
How to diagnose it step by step
- Check the oil and VVT solenoid.
- Check crank and cam sensor signals (an oscilloscope is ideal).
- Read cam deviation on the scan tool.
- Verify the timing marks.
- Replace the timing kit if stretched.
How to fix it
Rule out the sensors (cheap) and VVT solenoid first. If they are fine, check timing: on many engines (VW TSI, GM Ecotec, Mercedes) P0016 is the classic stretched-chain warning.
Estimated repair cost
Sensor: $30–150. Timing kit: $600–2,500 depending on the engine.
