P0014 on a 2012 Jeep Grand Cherokee
Exhaust Cam Over-Advanced (Bank 1, VVT)
P0014 on a 2012 Jeep Grand Cherokee indicates exhaust cam over-advanced (bank 1, vvt). It usually stays drivable short-term but should be diagnosed promptly. The most common cause is stuck or sludged exhaust-side vvt oil control valve (typically $100–$450). Confirm the root cause before replacing parts.
What does P0014 mean on a 2012 Jeep Grand Cherokee?
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.
This guide covers P0014 across the 2010-2014 Jeep Grand Cherokee generation — the symptoms, causes, and diagnostic steps below apply to every model year from 2010 through 2014.
Is it safe to drive a 2012 Jeep Grand Cherokee with P0014?
In most cases a 2012 Jeep Grand Cherokee stays drivable for short trips with P0014 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0014 on a 2012 Jeep Grand Cherokee?
- 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
What causes P0014 on a 2012 Jeep Grand Cherokee?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|

| Low engine oil level or pressure starving the exhaust cam phaser | Most common | $50–$200 |
| Sludged oil passages from skipped maintenance | Common | $100–$600 |
| Failed exhaust cam phaser / VVT actuator | Common | $600–$1,800 |
| Stretched timing chain affecting exhaust cam position | Occasional | $800–$3,000 |
| Damaged exhaust cam sensor wiring or connector | Occasional | $80–$350 |
How to diagnose this on a 2012 Jeep Grand Cherokee
-
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

About the 2010-2014 Jeep Grand Cherokee
The 2010-2014 Jeep Grand Cherokee was commonly sold with the following powertrains: 3.6L Pentastar V6, 5.7L HEMI V8, 3.0L EcoDiesel V6. Common trims include Laredo, Limited, Overland, Summit.
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
