P0019 on Jaguar
Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B
P0019 on Jaguar vehicles indicates crankshaft/camshaft position correlation - bank 2 sensor b. Au7o has documented this code across 2 Jaguar models — most commonly on XF, XK. This code means the engine computer detected that the crankshaft and camshaft positions on bank 2 (sensor B, typically the exhaust camshaft) are out of their expected correlation — in other words, the cam and crank timing don't line up correctly. The computer compares the crankshaft and camshaft position sensor signals to verify valve timing, which is often controlled by a variable valve timing (VVT) actuator. A correlation error points to mistimed valve events, frequently from oil-flow or VVT issues, a stretched timing chain, or sensor faults. You may notice rough idle, reduced power, poor fuel economy, or a check-engine light, and ignoring it can risk engine damage. Typical repair costs on Jaguar range from $4,000 to $8,500, depending on the specific model and root cause.
Common Causes of P0019
- •Stretched or worn timing chain (and worn guides/tensioner)
- •Faulty variable valve timing (VVT) actuator/solenoid (Bank 2)
- •Low oil level or dirty/sludged oil restricting VVT flow
- •Faulty camshaft or crankshaft position sensor
- •Clogged VVT oil control valve screen
- •Damaged sensor wiring or connector
- •Jumped/misaligned timing during prior service
P0019 on Jaguar by Model
Jaguar XF(1 issue)
- Timing Chain Tensioner Failure on AJ-V82009-2015
The Jaguar AJ-V8 engines in the XF suffer from hydraulic timing chain tensioner failure, causing chain slack on cold starts. The tensioner bleed-down allows the chain to rattle against the guides, and prolonged neglect leads to stretched chains and jumped timing, risking catastrophic valve-to-piston contact.
Jaguar XK(1 issue)
- Timing Chain Tensioner Failure on AJ-V82007-2015
The AJ-V8 engine in the XK shares the same timing chain tensioner weakness found across the Jaguar V8 range. The hydraulic tensioners bleed down when the engine is off, causing the timing chains to rattle on startup and progressively stretch until timing is compromised.

What does P0019 mean on Jaguar?▼
P0019 stands for "Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B." This code means the engine computer detected that the crankshaft and camshaft positions on bank 2 (sensor B, typically the exhaust camshaft) are out of their expected correlation — in other words, the cam and crank timing don't line up correctly. The computer compares the crankshaft and camshaft position sensor signals to verify valve timing, which is often controlled by a variable valve timing (VVT) actuator. A correlation error points to mistimed valve events, frequently from oil-flow or VVT issues, a stretched timing chain, or sensor faults. You may notice rough idle, reduced power, poor fuel economy, or a check-engine light, and ignoring it can risk engine damage. On Jaguar specifically, this code is documented across 2 models.
What causes P0019 on Jaguar vehicles?▼
Common causes on Jaguar: Stretched or worn timing chain (and worn guides/tensioner), Faulty variable valve timing (VVT) actuator/solenoid (Bank 2), Low oil level or dirty/sludged oil restricting VVT flow, Faulty camshaft or crankshaft position sensor, Clogged VVT oil control valve screen. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0019 on a Jaguar?▼
