P2004 on Chrysler
Intake Manifold Runner Control Stuck Open (Bank 1)
P2004 on Chrysler vehicles indicates intake manifold runner control stuck open (bank 1). Au7o has documented this code across 1 Chrysler model — most commonly on LHS. P2004 means the intake manifold runner control for engine bank 1 is stuck in the open position. Many engines use flaps or valves inside the intake manifold that close at low RPM to boost air velocity and torque, then open at higher RPM; this code sets when the computer commands those runners to close but a sensor shows they remain open. The result is usually rough low-speed running, reduced low-end power, or hesitation. It indicates a mechanical or actuator problem in the variable intake system, not a true vacuum or fuel issue. Typical repair costs on Chrysler range from $150 to $400, depending on the specific model and root cause.
Common Causes of P2004
- •Stuck or seized intake manifold runner flaps (carbon buildup)
- •Failed intake manifold runner control actuator or solenoid
- •Disconnected or broken actuator linkage/rod
- •Faulty intake runner position sensor
- •Damaged wiring or connector at the actuator/sensor
- •Vacuum leak or failed vacuum supply on vacuum-operated systems
- •Cracked or warped intake manifold

Chrysler LHS(1 issue)
- 3.5L V6 Intake Manifold Runner Control Failure1999-2001
The 3.5L V6 intake manifold runner control (IMRC) valve actuator fails, causing a loss of low-end torque and a check engine light. The IMRC system varies intake runner length for optimal power across the RPM range.

What does P2004 mean on Chrysler?▼
P2004 stands for "Intake Manifold Runner Control Stuck Open (Bank 1)." P2004 means the intake manifold runner control for engine bank 1 is stuck in the open position. Many engines use flaps or valves inside the intake manifold that close at low RPM to boost air velocity and torque, then open at higher RPM; this code sets when the computer commands those runners to close but a sensor shows they remain open. The result is usually rough low-speed running, reduced low-end power, or hesitation. It indicates a mechanical or actuator problem in the variable intake system, not a true vacuum or fuel issue. On Chrysler specifically, this code is documented across 1 model.
What causes P2004 on Chrysler vehicles?▼
Common causes on Chrysler: Stuck or seized intake manifold runner flaps (carbon buildup), Failed intake manifold runner control actuator or solenoid, Disconnected or broken actuator linkage/rod, Faulty intake runner position sensor, Damaged wiring or connector at the actuator/sensor. Specific causes vary by model and year — see the per-model sections below.
