P0019 on Ford
Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B
P0019 on Ford vehicles indicates crankshaft/camshaft position correlation - bank 2 sensor b. Au7o has documented this code across 1 Ford model — most commonly on F-150. 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 Ford range from $800 to $3,600, 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 Ford by Model
Ford F-150(3 issues)
- 3.5L EcoBoost cam phaser rattle on cold start2017-2020
Second-gen 3.5L EcoBoost engines develop a loud rattle/knock from the front timing cover for 2-5 seconds on cold start (and sometimes at idle). The variable-cam-timing (VCT) phasers have a lock pin that fails to engage on startup, allowing the phaser to rattle against the cam sprocket. Over time the phasers and timing chain wear, which can throw cam/crank correlation codes and, if ignored, lead to further timing component damage. Ford acknowledged it in service bulletins and a Customer Satisfaction Program with an extended warranty.
- 3.5L EcoBoost Primary Timing Chain Stretch — P0016 and Cold-Start Rattle2011-2017
Distinct from the cam-phaser cold-start rattle, the first-generation (2011-2016) 3.5L EcoBoost suffers genuine primary timing-chain wear ('stretch') because of its long chain routing and the high loads of a twin-turbo direct-injection V6. As the chain pins and rollers wear, the cam-to-crank relationship drifts and the PCM logs P0016 (and related correlation codes). The first symptom is usually a brief metallic rattle on cold start that worsens over time. Wear typically appears around 100,000-150,000 miles, often accelerated by extended oil-change intervals. Left unrepaired, the chain can skip teeth or break, causing catastrophic valve-and-piston contact. This is a high-demand search because the 3.5 EcoBoost is the volume engine in millions of F-150s.
- 5.4L Triton 3-Valve Cam Phaser / Timing Chain "Death Rattle"2004-2010
The 2004-2010 5.4L 3-valve Triton uses variable cam timing (VCT) phasers fed by clean, high-pressure engine oil. With infrequent oil changes or normal high-mileage wear, the phasers' internal vanes and locking pins wear out, the plastic timing-chain guides crack, and the hydraulic chain tensioners bleed down. The result is the notorious 'death rattle' — a loud rattle/knock on cold start and a metallic ticking at hot idle. Owners report symptoms as early as 50,000-100,000 miles. If ignored, a worn phaser or skipped chain can cause valve timing to drift (rough running, P0011/P0021/P0016 cam-correlation codes), loss of power, and in worst cases chain jump and valve-to-piston contact destroying the engine. This is one of the single most-searched, most-complained-about Ford truck engine problems of the era and a major shop money-maker.

What does P0019 mean on Ford?▼
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 Ford specifically, this code is documented across 1 model.
What causes P0019 on Ford vehicles?▼
Common causes on Ford: 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.
