P000B on RAM
"B" Camshaft Position Slow Response (Bank 1)
P000B on RAM vehicles indicates "b" camshaft position slow response (bank 1). Au7o has documented this code across 1 RAM model — most commonly on 1500. 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. Typical repair costs on RAM range from $150 to $3,200, depending on the specific model and root cause.
Common Causes of P000B
- •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

RAM 1500(1 issue)
- P0011 — Intake Cam Timing Over-Advanced from Clogged VVT Solenoid / Cam Phaser (5.7 Hemi)2009-2024
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.

What does P000B mean on 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 specifically, this code is documented across 1 model.
What causes P000B on RAM vehicles?▼
Common causes on RAM: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P000B on a RAM?▼
Repair costs on RAM range from $150 to $3,200, depending on the specific model and root cause.
