P0016 — Crankshaft/Camshaft Position Correlation (Bank 1 Sensor A) (6.7 Power Stroke)
Diagnostic reference for P0016 on 6.7 Powerstroke.
What it means
Crank and cam position signals are out of the expected phase relationship.1
Most likely causes
- Cam or crank sensor fault — Sensor signal missing/out of range or internal failure causing correlation error.1
- Reluctor-wheel damage — Damaged or contaminated tone wheel changes the edge timing seen by the sensors.1
- Wiring/connector issue to cam or crank sensor — Open, short, or corrosion in the sensor circuits produces implausible correlation.1
- Mechanical timing issue (rare) — Actual valve-train timing deviation can produce a persistent correlation fault.1
How to diagnose
- Verify code and freeze-frame data; confirm P0016 is current and note engine speed/load at set.
- Inspect camshaft and crankshaft position sensor connectors and wiring for corrosion, chafing, or loose pins.
- Check sensor supply voltage and ground per service information; look for intermittent signal dropouts.
- Examine reluctor wheels for missing teeth, debris, or damage using a borescope where accessible.
- Review recent repairs or timing-component work that could affect correlation.
- Clear codes, perform a controlled idle and light-load drive to see if correlation returns.
Parts and tools you may need
- Digital multimeter
- Oscilloscope or scan tool with live data graphing
- Borescope
- Basic hand tools for sensor access
Rough cost and difficulty
Parts and labor vary by shop and region; obtain a local estimate.
When to see a pro
If correlation persists after sensor/wiring checks, have a qualified diesel technician evaluate mechanical timing before further disassembly.
