The P2017 code indicates an issue with your intake manifold system. This specific description of “Intake Manifold Runner Position Sensor/Switch Circuit High” means that there’s an abnormally high voltage that the powertrain control module (PCM) has noted in the position sensor of the manifold airflow-control device. This specific code may also have “Bank 1” after it. In vehicles with two cylinder heads, this code will indicate a problem in cylinder #1.
More About Error Code P2017
The manifold airflow control device does two incredibly important things. First, it manages the speed at which the intake air flows through the manifold itself. That improves fuel atomization, which will increase engine power and reduce exhaust emissions. It also regulates the speed at which the manifold fills up with air. To do these things, your PCM needs to know where the intake manifold runner is at all times so it can adjust its position. This code signals that your vehicle is having an issue with the circuit for the position sensor.

What Are the Symptoms of a P2017 Code?
When your vehicle stores these codes, it’s likely to turn on the check engine light. Outside of this generic light, you may also see issues with a rough or fluctuating idle, as well as hesitating at certain engine speeds and general power loss, usually corresponding with certain engine speeds or throttle settings. These symptoms may change depending on how significant the problem is.
What Are Some Causes of a P2017 Code?
Issues with connectors are likely the most common cause of the P2017 code, including damaged, disconnected, corroded, and shorted wiring. There may be many other problems, however, including concerns with the vacuum lines, issues with the position switch or sensor, carbon deposits on the control flaps, or even a failing PCM, although this is an incredibly rare event. Some of these codes, including carbon deposits, are likely to come along with other diagnostic codes as well.
How Serious Is the P2017 Code?
The P2017 code is generally very serious. Even if you’re not experiencing significant drivability issues due to the P2017 code, you can start experiencing these issues at any time, especially if the problem has to do with corroded wiring and connectors, which can become more corroded over a fairly short period of time. You should approach this problem as though it is an exceptionally serious one, as issues with this code can eventually cause more concerns with your vehicle overall.
Can I Still Drive with a P2017 Code?
In many cases, you will still be able to drive physically with the P2017 code. However, this doesn’t just mean that you should proceed to keep driving when the code is active. The code should be a warning sign that there’s something very wrong with your vehicle. The earlier you mitigate that problem, the more likely you will be to fix the issue without any kind of significant long-term damage. When you see this code, stop driving immediately and talk to a professional about it.
How Easy Is It to Diagnose a P2017 Code?
The diagnosis process for a P2017 code is exceptionally difficult — so much so that non-professional mechanics are generally strongly urged away from handling this code and similar codes, including P2014, P2015, P2016, and P2018. This is because there are many different manifold air control system designs currently being used, so you need in-depth knowledge of the system your specific vehicle is using. It’s best to get professional assistance for this reason.
How Difficult Is It to Inspect a P2017 Code?
The inspection process can be difficult for similar reasons to the diagnostic process. Because this system looks so different in many vehicles, you may not be completely certain that you’re handling the code most effectively. This is one of the reasons why it’s so important to hand the problem over to a professional. With an expert’s assistance, you’ll be able to get help for the specific issues that your vehicle is experiencing, not a generic list of potential trouble spots.
Need Additional Help with Your P2017 Code?
The P2017 code is one of the codes that’s most likely to require help for the average layperson. Many people have a difficult time determining what the P2017 code means for their vehicle, which can lead to all manner of problems. Instead, talking to a professional tends to be the most effective path. The good news is that this path is indeed available.
The first step is to find a repair shop in your area with KBB. The service center locator will help you find the closest repair shop in your area.
Additionally, it’s common to see other codes with this code. If you’re seeing other codes and you want to learn more about what they mean, check out the KBB OBD-II database to gain that insight.
