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

P0016 on Land Rover by model: symptoms, diagnosis and fix
The Jaguar/Land Rover AJ-V8 5.0L engine suffers from timing chain tensioner failures. The hydraulic tensioners lose oil pressure on cold starts, allowing the timing chains to slap against the guides. Over time the guides wear and the chain stretches, leading to jumped timing and potential catastrophic engine damage. This is the single most expensive common failure on these engines.
Common Symptoms
- Rattling or whining noise on cold start lasting 2-10 seconds
- Check engine light with camshaft timing codes
- Rough idle after cold start
- Metallic rattling from front of engine
- Progressive worsening of startup rattle over weeks
How to Fix
Replace all four timing chain tensioners, timing chains, and chain guides. This is a major job requiring engine removal or substantial front-end disassembly. Use updated JLR tensioners (part number LR051013 superseded). Budget 20-30 hours labor at an independent specialist.

Owner tips & cautions
- WarningDo NOT ignore cold start rattle. Once the chain jumps timing, the engine is destroyed. Budget $5,000-$8,000 at a specialist. Dealer quotes of $12,000+ are common.

Frequently asked questions
What does P0016 mean on a Land Rover?
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 Land Rover it is documented across 1 model: Range Rover.
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 Land Rover?
Published repair estimates on Land Rover range from $4,000 to $8,000 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.
