P2008Intake Manifold Runner Control Circuit/Open (Bank 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2008 is the general circuit and open-circuit code for whatever drives the bank 1 flaps: a vacuum solenoid, a motor or a smart swirl actuator. GM's 2018 diesels with a feedback swirl actuator set it when the output stage sees more than 200 kΩ load in 12 of 15 samples (Type B, two trips), with the relay supply above 11 V; the 2014 Cruze diesel needs the open state for over 3 s, and the 2025 DC-motor design tests with the H-bridge off. On the Saab 9-5 2.0 TiD (2010) an open control line for 1 s is a Type A fault. Ford reports IMRC driver faults as P2008 after 5 s. FCA calls the same output the short runner valve: on the Ram 1500 a spread terminal in cavity 1 of the valve connector set P2008 with P2016/P2017. P2009 and P2010 separate short to ground and short to voltage; flaps usually rest in their default position.
- What you may notice
- Malfunction indicator lamp on
- Flaps stay in their rest position, less low-end torque or top-end power
- Likely causes
- LikelySpread or corroded terminal in the actuator or valve connector
- PossibleBroken control or supply wire to the bank 1 actuator
- PossibleOpen winding in the solenoid valve or actuator motor
- RareFaulty output stage in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €20 – €600
