2013 Ford F150 5.0 Coyote – P0024 Bank 2 Exhaust Cam Timing Over-Advanced – Need Advice Before Replacing Phaser

I have a 2013 Ford F150 5.0 with about 227k miles. The truck originally had only one code: P0024 (Bank 2 Exhaust Camshaft Position Timing Over-Advanced).

Truck runs and drives mostly fine overall. No loud cold start rattle, no chain slap noise, no rough idle, and oil pressure gauge stays normal. The only drivability issue is a slight jerking/shudder at highway speeds when lightly pressing the gas, which started after I unplugged ignition coils while replacing the VCT solenoid.

Here’s everything I’ve done so far:

- Oil was initially about 1 quart low
- Topped oil off to full
- Cleared code
- Code stayed away briefly but eventually returned
- Replaced the Bank 2 EXHAUST VCT solenoid (passenger side outer/front solenoid)
- Replacement solenoid was aftermarket from AutoZone
- Resistance on old solenoids tested around 7.6–8 ohms
- No metal found
- Engine sounds mechanically quiet

I then used FORScan to monitor live VCT data.

At idle:
- Desired timing = 0
- Actual timing = 0

While driving/cruising:
- Bank 2 exhaust desired angle goes to around 28–41 degrees
- Bank 2 exhaust duty cycle reaches 80%
- Actual Bank 2 exhaust cam position stays near 0 degrees and barely moves

Meanwhile Bank 1 behaves normally and tracks commanded timing correctly.

So basically:
- PCM is commanding Bank 2 exhaust cam movement
- Duty cycle increases heavily
- But actual cam timing barely responds

No other timing/correlation codes besides P0024.

At this point I’m trying to determine whether this sounds more like:
- sticking/failing Bank 2 exhaust cam phaser
- oil flow issue
- wiring/control issue
- defective aftermarket VCT solenoid
- or something else

Before I spend thousands on timing/phaser work:

  1. Is there anything else I should test first?
  2. Does this FORScan data strongly point to a sticking phaser?
  3. Would switching to an OEM Motorcraft solenoid still be worth trying?
  4. Could wiring or connector issues still realistically cause this exact behavior?

Any advice appreciated.
