P1004 on Chrysler
Short Runner Valve (SRV) Control Performance (manufacturer-specific)
P1004 on Chrysler vehicles indicates short runner valve (srv) control performance (manufacturer-specific). Au7o has documented this code across 1 Chrysler model — most commonly on LHS. P1004 is a manufacturer-specific powertrain code, so its exact meaning depends on the maker. On Chrysler, Dodge, Jeep, and Ram vehicles it most commonly indicates a Short Runner Valve control performance problem, where the engine computer detected that the intake manifold's variable-runner (SRV) flaps are not responding as commanded. On Volkswagen/Audi it instead refers to a cylinder 1 torque-difference fault. It generally points to an intake air-management or fueling concern that can affect smoothness and power. Typical repair costs on Chrysler range from $150 to $400, depending on the specific model and root cause.
Common Causes of P1004
- •Failed or stuck Short Runner Valve actuator/motor (Chrysler group)
- •Intake manifold runner control mechanism stuck or binding
- •Outdated PCM software requiring a TSB update
- •Wiring or connector fault to the SRV actuator
- •Carbon buildup restricting runner flap movement
- •Vacuum/electrical control problem
- •On VW/Audi: cylinder 1 fueling or compression imbalance
P1004 on Chrysler by Model
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.
