P0019 on Saturn
Crankshaft/Camshaft Position Correlation - Bank 2 Sensor B
P0019 on Saturn vehicles indicates crankshaft/camshaft position correlation - bank 2 sensor b. Au7o has documented this code across 2 Saturn models — most commonly on Aura, Vue. 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 Saturn range from $1,500 to $3,500, 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 Saturn by Model
Saturn Aura(1 issue)
- 3.6L V6 (LY7) Stretched Timing Chains2007-2009
The early GM 3.6L high-feature V6 (used in Aura XR) is prone to premature timing chain stretch, sometimes appearing as early as 50,000-100,000 miles. As the chains wear, camshaft-to-crankshaft timing drifts out of spec, setting correlation codes and eventually causing rough running, reduced power, and potential engine damage if ignored. A cold-start rattle is a common early warning sign.
Saturn Vue(1 issue)
- 3.6L High Feature V6 (LY7) Timing Chain Stretch2008-2010
The 3.6L 'High Feature' V6 used in the redesigned 2008-2010 Vue (and shared with Aura/Outlook/Acadia/CTS) is prone to timing chain stretch, often aggravated by extended oil-change intervals. As the chains and plastic guides wear, cam/crank timing drifts out of correlation, triggering the check-engine light, rough running, and a rattle on cold start. GM issued Information Bulletin 12-06-01-009F covering timing chain kit and guide replacement for DTCs P0008/P0009/P0016/P0017/P0018/P0019.

What does P0019 mean on Saturn?▼
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 Saturn specifically, this code is documented across 2 models.
What causes P0019 on Saturn vehicles?▼
Common causes on Saturn: 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 Saturn?▼
Repair costs on Saturn range from $1,500 to $3,500, depending on the specific model and root cause.
