P0011 on Ford: "A" Camshaft Position Timing Over Advanced or System Performance (Bank 1)
Severity: 2 of 4
Check your oil level right away, before driving further. If the oil is full and the engine idles smoothly, short careful trips to get it diagnosed are usually fine. If the oil warning light comes on, the engine stalls, knocks, or rattles loudly, park it, because oil starvation and timing faults can cause serious engine damage.
Estimate range covers the repairs listed below; see the cost breakdown. A flashing check engine light, a hot temperature gauge, or brakes that feel different mean stop driving and get help.
What P0011 usually means on a Ford
Ford calls its system variable cam timing (VCT). A Ford special service message (SSM 47170) says VCT codes, including P0011, can come from small debris making the VCT solenoid stick, and tells technicians to cycle the solenoid ten times with a scan tool to try to clear it before replacing parts. In 2025 Ford published a special service message (SSM 54366) for some 2015 to 2021 Ford and Lincoln vehicles with VCT codes, including P0011 and P0016, saying its pinpoint diagnostic test had been updated. Ask a Ford dealer or use current Ford service information rather than older test steps.
On older 5.4 liter three valve V8 trucks and SUVs, a Ford bulletin describes a rattle and rough idle at operating temperature caused by oscillating cam timing; the fix replaces both VCT solenoids. That bulletin lists bank 2 and cam sensor codes, but the same solenoids and oil pressure issues can set P0011 on bank 1.
Most likely causes on Ford vehicles
- Low or old engine oil
- Sticking VCT solenoid
- Low oil pressure
- Worn cam phaser or chain tensioner
Order reflects cost and likelihood in general; your vehicle may differ. Confirm with testing before buying parts.
Ford specific tips
- Check oil level and use the grade Ford specifies; VCT systems are sensitive to oil condition.
- Ask the shop whether they tried Ford's solenoid cycling step from SSM 47170 before replacing the solenoid.
- A rattle that comes and goes near idle when the engine is warm fits the 5.4 three valve bulletin; mention it to the shop.
- Confirm oil pressure before replacing phasers; a worn pump or tensioner seals can starve the system.
Estimated repair cost
This is an estimate, built from typical parts price ranges plus labor hours times an assumed shop rate of $110 to $190 per hour. Actual prices vary by vehicle, region, and shop. Diagnosis fees are often extra.
| Repair | Parts | Labor | Estimate (low / high) |
|---|---|---|---|
| Oil and filter change | $30 to $80 | 0.3 to 0.5 h | $30 + 0.3 × $110 = $63 $80 + 0.5 × $190 = $175 |
| Oil control valve (VVT solenoid) | $30 to $200 | 0.5 to 2.0 h | $30 + 0.5 × $110 = $85 $200 + 2.0 × $190 = $580 |
| Oil control valve filter screen cleaning | $0 to $20 | 0.5 to 1.5 h | $0 + 0.5 × $110 = $55 $20 + 1.5 × $190 = $305 |
| Cam phaser | $100 to $500 | 3.0 to 8.0 h | $100 + 3.0 × $110 = $430 $500 + 8.0 × $190 = $2,020 |
Costs are generic for this code; parts and labor on some Ford models may run higher.

FAQ
Do I need new cam phasers for a Ford P0011?
Not always. Ford guidance on the 5.4 three valve starts with the VCT solenoids, and oil level and pressure should be checked first.
Is there a Ford bulletin for P0011?
Ford SSM 47170 covers debris sticking the VCT solenoid, and SSM 54366 updates the diagnostic test for VCT codes on some 2015 to 2021 vehicles. Bulletins apply only to the vehicles they list, so check yours with a dealer.
