P0019 on Ram vehicles
Crank/Cam Correlation (Bank 2 Exhaust) — what it means on a Ram, whether it's safe to drive, and the fixes by model and year.
P0019 on a Ram means crank/cam correlation (bank 2 exhaust). Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is stretched timing chain or worn guides on the bank 2 side (typically $800–$3,500). Pick your Ram model below for its known failure patterns, recalls, and TSBs.
What does P0019 mean on a Ram?
P0019 is the Bank 2 exhaust-camshaft member of the P0016–P0019 correlation family. The ECM compares the crankshaft position signal to the Bank 2 exhaust ("B") camshaft position signal and finds them more than a calibrated number of degrees out of alignment. Because Bank 2 is the cylinder bank that does NOT contain cylinder number 1, P0019 only appears on engines with two banks — V6, V8, V10, V12, and flat / boxer layouts. The three explanations are almost always the same: timing chain stretch on that bank, a cam phaser that cannot return to base position, or a position sensor feeding bad data.
P0019 is a standardized OBD-II code, so its definition is the same on every Ram. What differs by model and engine is which cause is most likely — pick your Ram model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Ram with P0019?
In most cases a Ram stays drivable for short trips with P0019 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test. Exact tolerance depends on the model and engine.
What causes P0019 on a Ram?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Stretched timing chain or worn guides on the Bank 2 side | Most common | $800–$3,500 |
| Stuck Bank 2 exhaust cam phaser unable to return to base timing | Common | $400–$1,500 |
| Failed Bank 2 exhaust cam or crank position sensor producing offset readings | Common | $100–$400 |
| Low oil pressure preventing the phaser from holding position | Occasional | $50–$200 |
| Damaged or slipped Bank 2 exhaust reluctor / tone ring | Occasional | $300–$1,500 |
| Stuck-open Bank 2 exhaust VVT oil control valve | Occasional | $100–$450 |
| Timing chain skipped a tooth after a tensioner failure | Rare | $1,000–$4,000 |
Repair costs are typical US ranges and vary by Ram model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What are the symptoms of P0019 on a Ram?
Check Engine Light is illuminated. Cold-start rattle or chirp from the timing cover. Hard cold start with long crank times. Loss of low-end torque. Rough idle and reduced throttle response. Reduced fuel economy. Possible no-start if cam timing has slipped far enough
What causes P0019 on a Ram?
Stretched timing chain or worn guides on the Bank 2 side (most-common). Stuck Bank 2 exhaust cam phaser unable to return to base timing (common). Failed Bank 2 exhaust cam or crank position sensor producing offset readings (common). Low oil pressure preventing the phaser from holding position (occasional). Damaged or slipped Bank 2 exhaust reluctor / tone ring (occasional). Stuck-open Bank 2 exhaust VVT oil control valve (occasional). Timing chain skipped a tooth after a tensioner failure (rare)
