P0014 on a 2017 Ram 1500
Exhaust Cam Over-Advanced (Bank 1, VVT)
What does P0014 mean on a 2017 Ram 1500?
P0014 is set when the engine control module commands the Bank 1 exhaust camshaft to a specific advance position and the actual cam position does not match within tolerance. On engines with dual-cam VVT (intake + exhaust phasers), P0014 is the exhaust-side counterpart of P0011. The cause is almost always the same family of failures: a stuck oil control valve, dirty oil starving the phaser, or the phaser itself failing.
Symptoms on a 2017 Ram 1500
- Check Engine Light is illuminated
- Rough idle, particularly when the engine is hot
- Reduced low-end torque and slow throttle response
- Increased emissions at idle
- Possible engine stalling at low RPM
- Slight reduction in fuel economy
- Cold-start rattle from the cam area
Likely causes on a 2017 Ram 1500
- Stuck or sludged exhaust-side VVT oil control valve Most commonEstimated repair: $100– $450
- Low engine oil level or pressure starving the exhaust cam phaser Most commonEstimated repair: $50– $200
- Sludged oil passages from skipped maintenance CommonEstimated repair: $100– $600
- Failed exhaust cam phaser / VVT actuator CommonEstimated repair: $600– $1,800
- Stretched timing chain affecting exhaust cam position OccasionalEstimated repair: $800– $3,000
- Damaged exhaust cam sensor wiring or connector OccasionalEstimated repair: $80– $350
How to diagnose this on a 2017 Ram 1500
-
Confirm oil level, condition, and pressure first
VVT systems are oil-powered. Verify level is at full on a level surface with a warm engine, oil is clean (not dark or sludgy), and viscosity matches the OEM spec. Measure oil pressure with a mechanical gauge — typical 15–25 psi at idle, 40–60 psi at 2500 RPM. Low pressure must be fixed before chasing VVT parts.
Tools: Mechanical oil pressure gauge, Dipstick / level check
-
Read live exhaust cam position vs. commanded position
Scan-tool live data shows commanded and actual cam position. Watch while bidirectionally commanding cam advance. A working system tracks within 1–2 degrees of command. Lag of 5 degrees or oscillation points at the actuator or oil control valve.
Tools: Bidirectional scan tool with cam position PIDs
-
Inspect and clean the exhaust-side oil control valve
Remove the exhaust-side OCV. Check the inlet screen for sludge or metal debris. Bench-test with 12 V — the valve should click and open. Air should pass freely when energized and seal when de-energized. A sticking valve causes the most common P0014.
Tools: Socket set, Brake cleaner (NOT MAF-safe), 12 V test source, Compressed air
-
Listen for cam phaser noise at startup
A failing exhaust phaser often rattles at cold start for 1–3 seconds. Use a mechanic's stethoscope at the front of the cylinder head. The noise stops as oil pressure builds. Continuous rattle indicates advanced phaser wear.
Tools: Mechanic's stethoscope
-
Verify timing chain integrity (specific engines)
On engines with documented chain wear (BMW N20/N26, Ford 5.4 3V, VW EA888, GM 3.6 LFX), the phaser cannot fully advance once the chain has stretched — P0014 sets even with a perfect phaser. Check live cam-crank correlation drift under load.
Tools: Scan tool with cam-crank correlation
Common fixes
- Change engine oil and filter with the correct OEM viscosity
- Clean or replace the exhaust-side VVT oil control valve
- Replace the exhaust cam phaser / actuator assembly
- Replace stretched timing chain and components as a kit
- Repair damaged cam sensor wiring
About the 2015-2019 Ram 1500
The 2015-2019 Ram 1500 was commonly sold with the following powertrains: 5.7L HEMI V8, 3.6L V6, 3.0L EcoDiesel V6. Common trims include Tradesman, Big Horn, Laramie, Rebel, Limited.
P0014 vs P0011
These two codes describe the same kind of fault on different camshafts:
- P0011 — intake cam Bank 1 timing over-advanced
- P0014 — exhaust cam Bank 1 timing over-advanced
Engines with dual VVT have separate phasers and separate oil control valves for intake and exhaust. P0011 and P0014 setting together points to a common cause (oil pressure, sludge, common chain issue). P0014 alone isolates to the exhaust-side hardware.
Why oil maintenance matters more than the phaser itself
Most P0014 cases on engines with under 100,000 miles trace back to oil maintenance: extended intervals, wrong viscosity, or a slow oil leak that drops level over time. The cam phaser is mechanically robust if fed clean, high-pressure oil. A $50 oil change has resolved more P0014 codes than any other single repair.
Engines that disproportionately set P0014
- Toyota 2GR-FE V6 — exhaust OCV failure around 100k miles
- Ford 3.5L EcoBoost V6 (Gen 1) — phaser rattle leading to P0014
- Hyundai/Kia Theta II 2.4 GDI — both P0011 and P0014 from oil sludge
- GM 3.6 LFX/LLT V6 — chain stretch progresses from P0017 to P0014
