P0014
Camshaft Position "B" — Timing Over-Advanced (Bank 1)
Severity
medium
Worth booking. It costs fuel, emissions or comfort until it is fixed.
Can you drive it
Only if running normally
A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety.
Indicative cost (USD)
$100–$1,000
Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.

How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.
Common symptoms
- Check engine light
- Rough idle
- Hesitation under load
Likely causes
- Stuck VVT solenoid (exhaust)Most common
- Low/dirty oil
- Solenoid screen clogged

Cheapest-first ladder
- Live-data the commanded vs actual exhaust cam angle at idle and 2500 rpm warm — they should track within 2-3 degrees; an exhaust cam stuck advanced will throw rough idle and a hot-soak hard-start because it leaves the exhaust valve cracked open at TDC.
- Verify oil viscosity matches OEM spec — running 5W-30 in a 0W-20 engine is a common P0014 cause on Ford Coyote and Toyota 2GR.
- Clean the exhaust OCV screen — exhaust-side screens varnish faster than intake.
- Hot oil pressure test — below 10 psi idle means the phaser can't hydraulically respond. Don't condemn the exhaust cam phaser ($350-$700 part) or the timing chain on a P0014 alone — do the oil change with correct weight, OCV screen clean, and pressure test first.
Vehicle-specific patterns2004-2010 Ford F-150/Expedition 5.4L 3V Triton — the NOTORIOUS one.
- 2004-2010Ford F-150/Expedition 5.4L 3V Triton — the NOTORIOUS one. Cam phasers fail by 80-120k miles with a loud diesel-like rattle on startup, throws P0014 (and P0011/P0021/P0024 across all four phasers). Updated Ford phaser kit part 3L3Z-6A257-DA includes both intake and exhaust phasers, OCV solenoids, and timing chain — full job runs $1,800-$2,600 at a shop.
- 2007-2015Toyota Camry 2GR-FE V6 — exhaust OCV screen clog is the common cause, clean before condemning.
- 2011-2017Ford Mustang/F-150 5.0L Coyote — exhaust phaser lock pin breaks, cold-start rattle then P0014, replace phasers in pairs.
- 2009-2014Acura TL/MDX J35 — VCM-equipped engines collapse a lifter on the deactivated bank and throw P0014 as a secondary code.
Estimated repair$80 to $2,600.

P0014 — frequently asked
What does a P0014 code mean?
VVT exhaust cam (bank 1) timing over-advanced relative to commanded.
What causes a P0014 code?
Common causes: Stuck VVT solenoid (exhaust); Low/dirty oil; Solenoid screen clogged.
What are the symptoms of a P0014 code?
Typical symptoms: Check engine light; Rough idle; Hesitation under load.
Is it safe to drive with a P0014 code?
Only if running normally. A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety. Estimated repair: $100-$1,000.
How do I diagnose a P0014 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
