P0017 on Ram vehicles
Crank/Cam Correlation (Bank 1 Exhaust) — what it means on a Ram, whether it's safe to drive, and the fixes by model and year.
P0017 on a Ram means crank/cam correlation (bank 1 exhaust). Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is stretched timing chain or worn timing chain guides (typically $800–$3,500). Pick your Ram model below for its known failure patterns, recalls, and TSBs.
What does P0017 mean on a Ram?
P0017 is the exhaust-cam counterpart of P0016. The ECM compares the crankshaft position signal to the Bank 1 exhaust camshaft position signal and finds them more than a calibrated number of degrees out of alignment. This usually means timing chain stretch, a stuck cam phaser unable to return to base position, or a position sensor producing bad data. P0017 is one of the strongest indicators of timing chain wear on engines with dual VVT.
P0017 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 P0017?
In most cases a Ram stays drivable for short trips with P0017 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 P0017 on a Ram?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Stretched timing chain or worn timing chain guides | Most common | $800–$3,500 |
| Stuck exhaust cam phaser cannot return to base timing | Common | $400–$1,500 |
| Failed exhaust cam position sensor producing inaccurate readings | Common | $100–$400 |
| Low oil pressure preventing the phaser from holding position | Occasional | $50–$200 |
| Damaged exhaust cam reluctor wheel or tone ring | Occasional | $300–$1,500 |
| Stuck-open exhaust VVT oil control valve | Occasional | $100–$450 |
| Timing chain skipped one 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 P0017 on a Ram?
Check Engine Light is illuminated. Cold-start rattle or chirp from the front timing cover. Hard cold start with long crank times. Loss of low-end torque. Rough idle and reduced throttle response. Reduced fuel economy. Possible engine no-start if timing has slipped enough
What causes P0017 on a Ram?
