What P2008 means
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.
P2008 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2008
- Malfunction indicator lamp on
- Flaps stay in their rest position, less low-end torque or top-end power
Common causes of P2008
- Most 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
- Less likelyFaulty output stage in the engine control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2008 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 08 | The exact fault in that area. |
What to do next
- Note P2008 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2008
What does P2008 mean?
P2008 means "Intake Manifold Runner Control Circuit/Open (Bank 1)". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2008?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2008 fail an emissions test?
Yes, it can. P2008 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2008 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2008 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
