P000B on RAM by model: symptoms, diagnosis and fix
On the RAM 1500, P0011 is overwhelmingly a Variable Valve Timing (VVT) fault on the 5.7L Hemi, and secondarily on the 3.6L Pentastar V6. The Hemi uses a single central cam phaser fed oil pressure through one oil control valve (the VVT solenoid, mounted at the front of the engine near the timing cover). The PCM commands the phaser to a target intake-cam angle and monitors the actual angle via the cam/crank sensors. When the solenoid's fine oil screen clogs with sludge/varnish, or the solenoid sticks, oil flow to the phaser is no longer regulated and the intake cam advances past the commanded position — the PCM flags P0011 (over-advanced, bank 1). The root cause is almost always oil-related: extended oil-change intervals, low level, or off-spec/thick oil that will not flow through the small VVT passages, especially on cold starts. On higher-mileage Hemis, a P0011 (often alongside P0016/P000B) can also be the leading edge of the well-known Hemi cam/lifter wear failure — wear metal contaminating the oil seizes the phaser and solenoid, so P0011 should not be dismissed as 'just a solenoid' on a ticking, high-mileage engine.
Common Symptoms
- Check engine light with stored P0011
- Rough idle / occasional stumble, especially at cold start
- Slightly reduced fuel economy
- Hesitation or lack of power under acceleration
- Ticking noise (on higher-mileage Hemis where cam/lifter wear is involved)
- Hard start or brief rough running on cold mornings
How to Fix
Start with the cheap, high-yield steps: verify oil level and do a fresh oil-and-filter change using correct-viscosity oil (5W-20 on the Hemi), then clear the code and retest — dirty/degraded oil is the single most common trigger. If P0011 returns, replace the VVT/oil-control solenoid (clean the screen or renew), and perform the required cam/crank relearn afterward. If codes persist after a new solenoid, or the engine ticks and has high mileage, inspect the cam phaser, timing chain/guides and — critically on the Hemi — the camshaft lobes and lifters (MDS lifters), since VVT timing codes frequently accompany the cam/lifter failure. On the 3.6 Pentastar, also confirm the oil-filter-housing/cooler is not leaking and starving oil pressure.

Frequently asked questions
What does P000B mean on a RAM?
P000B stands for ""B" Camshaft Position Slow Response (Bank 1)." The same generic SAE-defined VVT diagnostic as P000A but for the bank 1 'B' camshaft — normally the exhaust camshaft. The PCM commands the exhaust cam phaser to a target angle and compares the actual camshaft position (from the CMP sensor) against the crankshaft reference. P000B sets when the camshaft responds too slowly to the command or does not reach the commanded position within the calibrated window. On RAM it is documented across 1 model: 1500.
What are the most common causes of P000B?
The most common causes of P000B are: Low or degraded oil, or oil of the wrong viscosity, starving the exhaust cam phaser, Restricted oil feed passage or clogged VCT solenoid screen, Sticking or failed exhaust cam oil control valve (VCT solenoid), Worn exhaust cam phaser, Stretched timing chain, worn guides or a weak tensioner, VCT solenoid circuit wiring / connector fault. The specific cause varies by vehicle.
How much does it cost to fix P000B on a RAM?
Published repair estimates on RAM range from $150 to $3,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
