Bank 2 exhaust cam correlation fault.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Bank 2 Sensor B (exhaust cam) — Crank-to-Cam correlation fault on bank 2 exhaust. Mirror image of P0017 but on bank 2. Often appears with P0018 on V-engines with stretched chains, or alone with a failed bank 2 exhaust OCV or phaser.
Cheapest-first ladder
- Look for paired codes — P0016/P0017/P0018/P0019 together is a chain-stretch slam-dunk on shared-chain V-engines.
- Live-data bank 2 exhaust cam correlation, watch for rpm-dependent drift.
- Swap bank 2 exhaust OCV with bank 1 exhaust OCV to isolate solenoid from cam-side hardware.
- Inspect bank 2 exhaust cam sensor.
- Visual chain inspection at the valve covers. Don't approve a chain job on a lone P0019 — exhaust-side single-bank codes are most often OCV solenoid failures, which are 1/20th the cost of a chain job.

What are the symptoms of a P0019 code?
Typical symptoms: Check engine light; Rough idle.
Is it safe to drive with a P0019 code?
Not for long. Driving on this one risks further damage. Get it to a shop rather than carrying on with it. Estimated repair: $200-$2,500.
How do I diagnose a P0019 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
