Trouble code
P0011: camshaft timing
The same code points to different failures on different engines. Below, engine by engine, are the documented failures whose records name P0011, with the record's own words, how to tell them apart and the usual fix. The meaning above is taken from the record Cam phaser / VCT rattle and cam-timing DTCs.

1 documented failure names this code. All about this engine
verified
How widespread: Very common
87 NHTSA owner complaints match it, out of 7,111 checked
Where its record names the code
- timing/cam DTCs (P0011/P0012 family) with the rattle
Its other signs
- a loud diesel-like rattle on cold start that fades as oil pressure builds
- rattle at hot idle, occasionally with a rough first few seconds
- check-engine light with cam timing codes
How to tell it apart
- confirm the noise is at cold start and fades with oil pressure (phaser signature)
- scan for cam-timing DTCs; check VCT solenoid operation
- oil condition first - sludge both causes and mimics phaser noise
Usual fix
replace the phasers (in pairs) with the timing chain kit while the front end is open; check VCT solenoids

3.5 EcoBoost (gas)
1 documented failure names this code. All about this engine
aggregated
How widespread: Very common
107 NHTSA owner complaints match it, out of 667 checked
Where its record names the code
- MIL with cam-timing DTCs (P0011/P0015/P0016-P0019/P0021/P0025) or VCT circuit codes (P0365/P0369)
Its other signs
- cold-start rattle or ticking that fades as oil pressure builds
- rough or delayed cold start
- PCM updates required after VCT unit or long-block replacement (per Ford SSM)
How to tell it apart
- listen for the cold-start rattle versus a deeper knock; warm-engine repeat check
- scan cam-timing and VCT DTCs on both banks; freeze-frame at start
- verify oil level/condition and oil-filter type before condemning phasers
Usual fix
phaser / VCT unit replacement with the updated hardware and the PCM calibration update; oil-system service while in there

A code tells you which system flagged a fault, not which part failed. Read it with the signs your truck shows: symptoms by engine. For your exact truck: check your VIN.
