When the P2017 code shows up, your car’s PCM (that’s the powertrain control module, or the main computer) has picked up a problem with the electrical circuit tied to the intake manifold runner position sensor on Bank 1. In my experience, this sensor is crucial for the engine to keep tabs on those little flaps inside the intake manifold-flaps that adjust how much air gets into your engine’s cylinders. The IMRC (that’s Intake Manifold Runner Control) system moves these flaps to help your engine breathe right at different speeds and loads. So, when the PCM sees a signal from the sensor that’s reading too high or just plain out of whack, it’ll throw a P2017 code. I see this setup all the time, especially on cars built after 2003. It’s there to squeeze out better fuel economy, give you more punch when you need it, and keep emissions in check.

From my time in the shop, I can tell you that p2017 usually boils down to a handful of usual suspects. Nine times out of ten, it’s either the IMRC actuator itself or the relay that controls it. Sometimes it’s just bad wiring or, once in a blue moon, the PCM decides to go haywire. Here’s what I see most often when a car rolls in with this code:
- IMRC actuator relay gone bad
- Faulty IMRC actuator or the runner position sensor itself
- Wiring harness gremlins-broken wires or connectors that have seen better days (corrosion is a common culprit)
- Defective PCM-not as common, but it absolutely happens
Always start with what’s easy and obvious before assuming it’s the worst-case scenario.
dtc P2017 Symptoms
When your vehicle throws a dodge dtc p2017, you’ll notice it. The check engine light’s the first thing to greet you. You might feel the engine stumble or run rough, especially if you put your foot down. Sometimes it mimics a misfire or just feels gutless on acceleration. Fuel economy? That’ll take a hit too, since the air/fuel mix won’t be right. I’ve seen some cars just feel lazy-like they’ve lost their edge or aren’t as responsive as you remember.
P2017 trouble code Diagnosis
Let me walk you through how I like to chase down a dtc p2017. First off, grab a scan tool and confirm the code-don’t just rely on that check engine light. Check for any other codes riding along, as those can point you in the right direction. After that, I always pop the hood and look things over: connectors at the IMRC actuator and its relay, anything loose, damaged, or looking crusty with corrosion. Give the wiring harness a good look too, especially for broken or chewed-up wires. Mice love a warm engine bay. If you’ve got a helper, have them wiggle the harness while you watch for changes or test the actuator. Then, break out your multimeter and check for proper voltage and ground at the actuator’s connector. If the wiring checks out, it’s time to test the relay-sometimes I’ll swap in a known good one just to rule it out fast. If none of that solves it, you could be staring down a bad actuator or, on rare occasions, a flaky PCM. Take your time on each step; missing something simple can cost hours chasing ghosts.

A classic mistake I see? Folks yank out the actuator or even swap the PCM right away without giving the wiring and relay a fighting chance. Another one-overlooking crusty or greened-up connectors. Those can mess with signals and throw all sorts of weird codes. I’ve also seen people clear the code and cross their fingers it won’t come back. That’s wishful thinking and a recipe for trouble down the road. Here’s a pro-tip from the garage: always check for technical service bulletins (TSBs) for your make and model. Sometimes the factory already knows about the issue and has a fix or an updated part.
obd code P2017 Seriousness
I’ll be straight with you-this isn’t a code you want to ignore. Sure, you might not get stranded the minute it pops up, but driving around with a dtc p2017 dodge can mean your engine’s not running right. That means sluggish performance, lousy mpg, and in some cases, potential for real engine damage if the problem causes a lean condition or misfire. I’ve seen catalytic converters get toasted from problems like this being left unchecked. So, while you might be tempted to let it slide, it’s much smarter to get on top of it before those minor symptoms turn into a major repair bill.
P2017 code Repair
When I’m fixing a dtc p2017, I always let the diagnosis guide me. Here’s what usually gets the job done:
- Swap out a bad IMRC actuator relay if it’s not kicking on like it should
- Fix or replace any damaged wiring or connectors you find in the IMRC circuit
- Replace the IMRC actuator or the runner position sensor if they’re not working right
- If there’s a known software issue, update or reflash the PCM-TSBs are your friend here
- In rare cases, if the PCM’s the culprit and you’ve ruled everything else out, it’ll need to go
Stick with OEM parts and always follow the manufacturer’s repair steps for your specific ride. It’ll save you headaches and make sure the fix lasts.
Conclusion
Bottom line, when you see P2017, your intake manifold runner control system’s not giving the right feedback, and that spells trouble for both performance and fuel economy. It’s something you want to fix sooner rather than later-waiting can just make things worse and pricier. Start by checking the relay, actuator, and wiring-don’t skip the basics. Once you find what’s faulty, the solution is usually straightforward. If electrical work isn’t your thing, there’s no shame in handing it off to a pro. That way, you’ll get your car sorted and back on the road without gambling on bigger problems down the line.
