Exhaust valve timing solenoid or a phaser locked to far in advance. Have you done the timing job yet?
If not be sure to use motorcraft stuff. Ford had 3 renditions of an upgraded vvt and if you bought after market that could be it. Also check wiring

I just purchased 1800.00 worth of parts for my final repair attempt. Comp cams, phaser lockouts, Tuner and all new followers.
We'll see how this turns out. I'm hoping it doesn't turn into a dumpster fire

For those using Torque Pro or another type OBDII scanner that permits inputting custom PIDs and formulas - I have located and worked out formulas for monitoring all the OBDII variable valve timing signals on the Triton engine ('04 through '08 for sure, possibly many others).

Example:




VARIABLE CAM / PHASER monitoring screen in Torque Pro


AccPedal is the Accelerator Pedal Absolute position
Load and RPM's are self explanatory
VCTENA, VCTA, VCTF and CMPFM (Cam Position Sensor FAULT MODE) are flag bits maintained by the VCT system. You can add other gauges in Torque Add gauge as desired


The screen is laid out with Bank 2 on the left and Bank1 (passenger side) as the world looks from the drivers seat.


RCAM 2 And RCAM are the PCM's requested Retard in Crankshaft Degrees for cams on Bank2 and Bank1 respectively
VCT2DC and CAMDCR are VCT Solenoid duty cycle for Bank 2 and bank 1 respectively.


MAF is Mass Air Flow gauge
IMRC is Intake Manifold Runner Control ON/OFF (Open/Closed) indicator
FICM / SYNC is FICM fault and Crank/Cam sync flag

VCT2ERR and CAMERRR is Camshaft Retard Error +/- camshaft degrees that the camshafts for Bank2 (on left) and Bank1 (on right) are OFF from the PCM's 'requested' retard for That Bank.


VCT2ERRT and VCT1ERRT are custom PIDs I created consisting of a SUM of Camshaft Retard Error. They have no specific numeric relationship, but indicate if "+"and "-" Cam error are about equal. They go above and below zero unless a cam spends more time in the negative or positive territory. It seems it would be indicative of a problem if it gets too far above or below zero with time.

-------------------

If you have the latest version of Torque Pro, I am attaching a 'CSV' file containing the 13 PIDs. It can be copied into the .Torque/extendedpids directory on your Android phone and simply IMPORTED the F150_VCT_MONITOR.CSV file into Torque directly. If not, you can (carefully & accurately) key in each of the following thirteen (13) custom PIDs, then create a dashboard page similar to the one I'm using as depicted above. Then begin monitoring / logging / graphing your variable cam operation with live data. (NOTE: I have placed an underscore ("_") character in front of each PID name to cause them to sort to the front of the sensor list in torque when you are selecting PIDs for dashboard gauges.)

Also NOTE: In ALL PIDs, Scale Factor = 1, Header = Auto / or Blank, Diagnostic Start = blank, Diagnostic end = blank

Hope the Scanner Users out there fine this helpful.

Cheers F150-Torqued

PS: I notice when I download the attached CSV file, my computer assumes it is an EXCEL file - which 'csv' technically IS. Android wants it in a 'FLAT' text file without any Excel bells and whistles. "SAVE" the file to your computer instead of "OPENING" it. Then copy the file directly to the .Torque/extendedpids folder and everything will go smooth.


-----------------------EDIT 8/18/2017
Updated CSV file with version v 1-03 and corrected gauge & formula for FICMSYNC


--------------------- EDIT 09/12/2017
Updated CSV file with version 1-04 adding PID for RCAM2 and photo including gauge for newly discovered PID for RCAM for Bank2
This EDIT is posted to correctly represent and report all OBDII information presented by the PCM concerning variable valve timing components. I did not realize (and still do not understand why) the PCM calculates a separate degree CAM RETARD for Bank 1 and Bank 2. But clearly it does - and with this change these PIDs & Torque Equations allows you to accurately represent all known PIDs controlling variable valve timing on the 5.4L 3v engine with Torque Pro.
----------------------- EDIT 08/26/2018
Updated Bit oriented formulas per latest version of Torque pro. And updated CSV file to V-1-06

I did not know for sure, but have encountered differences in PID assignments even between identical years and model that were 'assembled' at different assembly plants. DAMN its frustrating. The two accumulators working make perfect sense. They are not real PIDs that come from the vehicle but rather memory variables I created. They stay zero or empty because the PIDs they should be accumulating aren't responding on your vehicle.

I have no idea how to find or obtain PIDs for your truck. Damn manufacturers keep that stuff proprietary so their techs can CHARGE THE HECK OUT OF US. On my '04, I ran a complete sequential 'SCAN' of every possible PID number from 0000 to FFFF (Took hours) and recorded all responses. Then set out on the task of figuring out what each response represented. (Not an easy chore). I had no idea - but quickly learned - the effort was only applicable to 2004 thru 2008.
