The P2008 code definition is “Intake Manifold Runner Control Circuit/Open Bank 1.” This code means that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected a problem with the vehicle’s intake manifold runner control circuit, specifically the circuit in Bank 1. Notably, this doesn’t mean there’s an actual problem with the intake manifold system, just that this control circuit is not responding with the proper voltage. As a generic powertrain code, error code P2008 can pop up in any OBD-II-equipped vehicle with the intake manifold runner control circuit.
More About Error Code P2008
The intake manifold runner control system is part of the intake manifold system in newer vehicles, and it helps your vehicle maintain the air/fuel ratio more efficiently, especially at low speeds. The intake manifold system lets air into the combustion chamber, and in many vehicles, it also helps it mix with fuel from the fuel injector before entering the combustion chamber. The intake manifold runner opens and closes a series of butterfly valves to create the most efficient levels of manifold pressure and flow. Although it isn’t 100% necessary, it is an important part of having your vehicle function at optimal capacity.

What Are the Symptoms of a P2008 Code?
Some vehicles will have no symptoms other than an illuminated check engine light. In some cases, even the check engine light will only turn on when the problem occurs, as this is considered a soft code that only sometimes maintains a permanent engine code. However, many vehicles will exhibit at least some drivability symptoms. This may include a rougher than normal idle, issues with surging, a reduction in torque at low speeds, and even hard starts. In some cases, this can develop into a no-start condition. Always handle this problem early on to avoid the more serious symptoms.
What Are Some Causes of a P2008 Code?
The intake runner control solenoid and swirl flaps are two of the most common causes of the P2008 code. The solenoid tends to be in a spot subjected to heat and dirt, causing a dirty filter and a failed solenoid, while the swirl flaps may become covered with soot and locked in a specific position. Other problems may include broken vacuum lines, poor electrical connection, and an open or short in the wiring harness.
How Serious Is the P2008 Code?
The P2008 code is not critical, especially at first, but having a problem with the intake manifold runner control circuit can have repercussions over time. You may see significantly reduced power, especially during acceleration, and handling during low engine speeds is much more difficult. The severity may change depending on whether there are underlying problems with the intake manifold runner, with it not functioning at all, and what position the control circuit was in when it failed. Overall, it’s not something you must pull over and fix immediately, but you should fix it when possible.
Can I Still Drive with a P2008 Code?
You should avoid driving with the P2008 code. While this code does not show up as significantly as some others, and you might not even notice any drivability symptoms near the beginning, it’s important to remember that the more you drive with any diagnostic trouble code active, the more likely you are to experience issues. Especially when it comes to a code that can progress to a no-start condition, you should avoid driving and instead seek help to fix the problem.
How Easy Is It to Diagnose a P2008 Code?
There are multiple possible diagnoses for the P2008 code, and when there are multiple causes, that can make the diagnostic process more difficult. This is helped by the fact that the problem often lies with the manifold runner control solenoids or the swirl flaps themselves, but you can only replace these components by going through the diagnostic flowchart. While some people can diagnose the problem themselves, many will benefit from talking to an expert.
How Difficult Is It to Inspect a P2008 Code?
Inspection of a P2008 fault code can be difficult because it frequently involves vehicle components you only sometimes deal with. You might not know how to detect the problems that often plague code P2008, which can be frustrating and difficult to manage. Plus, if your scan tool indicates additional codes, you must know how they overlap. A certified mechanic can determine the underlying problem without making any mistakes that might require a follow-up repair.
Need Additional Help with Your P2008 Code?
These vehicle components are complicated, and you might need help with them. If you decide to get help with code P2008, many options are available.
Start by finding an auto repair shop in your area. A local automobile repair shop will be able to give you more insight into the problems you’re experiencing and how you can fix them. Plus, you don’t have to worry as much about driving a vehicle that might not be at top capacity.
