P0016 — Crankshaft/Camshaft Position Correlation (Bank 1 Sensor A) — 6.7 Powerstroke
P0016 on 6.7 Powerstroke means the PCM sees crank and cam signals out of expected phase. Diagnose sensor/wiring/reluctor issues first; mechanical timing is…
What it means
Crank and cam position signals are out of the expected phase relationship.1
Most likely causes
- Cam or crank position sensor fault — Sensor output missing, erratic, or out of range; connector corrosion or wiring damage can cause correlation error.1
- Reluctor-wheel damage or debris — Damaged/missing teeth on crank or cam reluctor changes signal pattern and phase.1
- Wiring/connector issues to sensors — Chafed, corroded, or loose wiring alters signal integrity between sensors and PCM.1
- Rare mechanical timing issue — Rare on this platform. Worn or mis-indexed timing gears can shift cam-vs-crank phase; mechanical timing is uncommon versus sensor, reluctor-wheel, or wiring faults.1
How to diagnose
- Verify freeze-frame and repeatability of P0016; check for accompanying misfire/contribution codes.
- Inspect cam and crank sensor connectors and wiring for corrosion, chafing, and proper seating.
- Check sensor supply voltage and ground per service info; look for intermittent signal dropouts with a scope.
- Inspect reluctor wheels for damage, debris, or misalignment; compare crank vs cam signal patterns.
- If electrical checks pass, evaluate mechanical timing integrity before assuming internal engine work.
Parts and tools you may need
- Digital multimeter
- Lab scope
- Service information for pinouts and signal specs
- Inspection mirror and borescope
Tools you’ll need
- digital storage oscilloscope — Compare crank vs cam signal patterns to verify phase relationship and detect dropouts for P0016.
- OBD-II scan tool — Read freeze-frame data and confirm repeatability of P0016 along with related misfire codes.
- digital multimeter — Check sensor supply voltage, ground integrity, and wiring continuity to cam and crank sensors.
Rough cost and difficulty
| Likely repair | Parts | Shop labor | Who usually does it |
|---|---|---|---|
| ECM/PCM software update | — | 0.5–1.5 hrs | Shop |
| Wiring or connector repair | $10–$100 | 1–4 hrs | DIY with tools and a manual |
| Crankshaft or camshaft position sensor | $40–$200 | 0.5–2 hrs | DIY with tools and a manual |
| Engine wiring harness section | $100–$500 | 2–5 hrs | Shop |
Typical US independent-shop figures; labor runs about $120–$180 per hour (dealers charge more). Confirm the diagnosis before buying parts.
When to see a pro
If scope patterns are abnormal or mechanical timing is suspected, have a qualified diesel technician confirm timing integrity before disassembly.
Check for recalls
Recalls are tied to your truck’s VIN, so check yours directly: enter the VIN at NHTSA’s recall lookup. Open safety recalls are repaired free at a dealer.
