P0019
Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)
The engine computer sees the crankshaft and bank 2 sensor B camshaft signal not lining up. On most engines, sensor B is the exhaust cam on bank 2. Common causes are stretched timing components, oil-related VVT problems, or a bad cam or crank signal.

Quick answer
AI-CITATION READYWhat it means
Can you drive with it?
Most common causes
- Stretched timing chain, worn guides, or weak tensioner
- Low, dirty, or incorrect engine oil affecting bank 2 VVT operation
- Faulty bank 2 exhaust cam phaser or VVT solenoid
Typical repair cost
DIY usually runs $20-$300. Typical shop repair lands around $180-$1,800, depending on the root cause.
01 / Definition
P0019 means the PCM has detected a correlation fault between the crankshaft position sensor and the camshaft position sensor for bank 2 sensor B. On many vehicles sensor B identifies the exhaust camshaft on bank 2. The code sets when actual cam timing does not match expected crankshaft position, usually because of timing chain wear, VVT control problems, incorrect oil condition, sensor faults, or incorrect mechanical timing after repair.
02 / Drive status
With caution. Drive only if necessary and only if the engine is not rattling, stalling, or running very rough. If timing has jumped or the chain is loose, continued driving can damage the engine.
03 / Symptoms
- Check engine light
- Rough idle
- Hard starting
- Loss of power
- Engine hesitation
- Misfires
- Timing chain noise
- Stalling in some cases
04 / Causes
| 1 | Stretched timing chain, worn guides, or weak tensioner | high |
|---|---|---|
| 2 | Low, dirty, or incorrect engine oil affecting bank 2 VVT operation | high |
| 3 | Faulty bank 2 exhaust cam phaser or VVT solenoid | medium |
| 4 | Bad camshaft or crankshaft position sensor signal | medium |
| 5 | Damaged wiring, poor connector contact, or oil contamination in the sensor circuit | medium |
| 6 | Mechanical timing installed incorrectly after engine work | low |
05 / Diagnostic sequence
- 01Check engine oil level, condition, and correct viscosity first.
- 02Scan for related codes such as P0017, P0018, P0345, P0365, P0335, or oil control codes.
- 03Use live data to compare crankshaft and bank 2 exhaust cam correlation and commanded versus actual cam movement.
- 04Inspect the bank 2 sensor B cam sensor connector and harness for oil intrusion, loose pins, or wiring damage.
- 05Test the crankshaft and camshaft sensor signals if the scan data shows dropouts or unstable timing.
- 06Command the bank 2 VVT solenoid if supported and watch whether actual cam angle responds correctly.
- 07Listen for timing chain noise and inspect mechanical timing if correlation remains out of range.
- 08Clear the code after repair and confirm the fault does not return during a road test.
06 / Repairs
| 1 | Correct low oil level and change dirty or incorrect engine oil | $20-$120 |
|---|---|---|
| 2 | Repair damaged wiring, connectors, or oil contamination in the cam or crank sensor circuits | $20-$200 |
| 3 | Replace a faulty crankshaft or camshaft position sensor if testing proves the signal is wrong | $40-$250 |
| 4 | Replace a failed bank 2 VVT solenoid or cam phaser | $80-$900 |
| 5 | Repair stretched timing chains, guides, tensioners, or incorrect mechanical timing | $700-$1,800 |

08 / FAQ
What does P0019 mean?
It means the engine computer detected a crankshaft and bank 2 sensor B camshaft timing mismatch.
Is P0019 serious?
Yes. Timing correlation faults can be caused by chain wear, VVT faults, or incorrect mechanical timing.
Can dirty oil cause P0019?
Yes. Dirty or low oil can keep the cam phaser and VVT system from moving correctly.
Is sensor B always the exhaust cam?
Usually, but check service information because sensor naming can vary by manufacturer.
Will clearing P0019 fix it?
No. The code usually returns until the timing, oil, VVT, or sensor problem is repaired.
