P0016 on Volvo: How to Diagnose & Fix
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A

P0016 on Volvo by model: symptoms, diagnosis and fix
The Volvo V40 with the 1.9T engine (a Volvo modular engine) is an interference engine requiring strict timing belt maintenance. Belt failure causes catastrophic valve and piston damage. The belt and tensioner must be replaced together.
Common Symptoms
- Belt squealing
- Oil leak at the timing cover that can soak the belt
- Engine will not start if belt has snapped
How to Fix
Replace the timing belt together with the tensioner and idler (commonly the water pump at the same time) at the scheduled interval; a commonly listed interval for the 2000-2004 V40 1.9 L turbo is about 60,000 miles, and age, heat and an oil-soaked belt justify earlier replacement. Check your owner's manual or a Volvo dealer for the exact interval for your car. If the belt has already snapped, do not keep cranking the engine; have a compression or leak-down test done to assess valve damage before deciding on repair.

Frequently asked questions
What does P0016 mean on a Volvo?
P0016 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor A." P0016 means the engine computer found that the crankshaft and camshaft position sensors on Bank 1 (Sensor A) are not lining up the way they should — the timing 'correlation' between them is out of range. These two sensors tell the computer where the pistons and valves are so it can time fuel injection and spark precisely. When their signals don't agree within tolerance, the computer sets this code. It generally indicates an engine timing issue, which may be a worn timing chain, a sticking variable valve timing component, or a sensor problem, and can cause rough running, hard starting, or potential engine damage if ignored. On Volvo it is documented across 1 model: V40.
What are the most common causes of P0016?
The most common causes of P0016 are: Stretched timing chain or worn timing components (guides/tensioner), Faulty camshaft position sensor or crankshaft position sensor, Stuck or faulty variable valve timing (VVT/VCT) actuator or solenoid, Low or dirty engine oil affecting the VVT actuator, Clogged oil control valve or restricted oil passages, Timing chain/belt installed one tooth off after service, Damaged reluctor/tone ring on the crankshaft or camshaft, Wiring or connector faults at the position sensors. The specific cause varies by vehicle.
How much does it cost to fix P0016 on a Volvo?
Published repair estimates on Volvo range from $400 to $3,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
