P0019 on Chevrolet vehicles indicates crankshaft/camshaft position correlation - bank 2 sensor b. Au7o has documented this code across 2 Chevrolet models — most commonly on Camaro, Traverse. 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 Chevrolet 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 Chevrolet by Model

Chevrolet Camaro(1 issue)

  • Timing Chain Stretch and Correlation Faults on 3.6L LLT/LFX V62010-2015

    The 3.6L direct-injected V6 used in fifth-generation Camaro is known for timing chain wear/stretch that can trigger cam/crank correlation faults, rough running, and reduced performance. GM issued service information and special coverage on related 3.6L timing chain concerns across multiple applications, and Camaro owners have documented the same issue in forums and complaints. Poor oil maintenance tends to accelerate wear because chain life is sensitive to lubrication quality and oil change intervals.

Chevrolet Traverse(1 issue)

  • Timing Chain Stretch and Failure (3.6L V6 LLT/LFX)2009-2017

    The 3.6L V6 (LLT and LFX variants) in the first-generation Traverse is notorious for premature timing chain stretch. The engine uses three timing chains — one primary and two secondary chains driving the variable valve timing actuators. The chains stretch beyond the tensioner capacity, causing the engine timing to slip. Symptoms progress from a rattle on cold start to a check engine light with camshaft correlation codes. If ignored, the stretched chains can skip teeth, causing catastrophic engine damage. The issue typically manifests between 80,000-120,000 miles.

Frequently Asked Questions

What does P0019 mean on Chevrolet?▼

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 Chevrolet specifically, this code is documented across 2 models.

What causes P0019 on Chevrolet vehicles?▼

Common causes on Chevrolet: 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 Chevrolet?▼

Repair costs on Chevrolet range from $1,500 to $3,500, depending on the specific model and root cause.
