When you see a P2014 pop up on your scanner, your car’s computer-technically the PCM-is telling you something’s off with the intake manifold runner position sensor or switch. In my experience, that sensor is basically the watchdog for a flap or valve inside your intake manifold. Picture it like a bouncer at a club, deciding how much air gets into the engine at different times. The whole setup is there to help your engine run smoother, pull harder, and squeeze out every drop of fuel efficiency, whether you’re cruising or mashing the pedal. If the PCM gets a reading from the sensor that just doesn’t make sense-maybe it’s jumping all over, stuck low, or pegged high-it’ll throw the P2014 code. Some folks call this whole deal the intake manifold runner control system. Not every engine uses it, but if your car does, it’s a critical piece for keeping things running crisp and your miles-per-gallon up.

6 minutes of readingCauses of P2014
From my years in the shop, the reasons behind a P2014 code are usually right in front of you if you know where to look. Here’s what tends to trip it:
- Faulty intake manifold control valve-the part that actually opens and closes, managing the airflow.
- Intake manifold position sensor gone bad-these sensors fail or get stuck more often than you’d think.
- Runner control actuator failure-the little motor or mechanism that’s supposed to move the valve can give up the ghost too.
- Throttle body or throttle plates acting up-gunked up or sticky components here can throw the whole system off balance.
- Vacuum line issues-cracked, unplugged, or blocked vacuum hoses are a classic culprit.
- Trouble with wiring or connectors-broken wires, corroded plugs, or loose connections can turn a simple issue into a head-scratcher.
- And, every now and then, a bad PCM is to blame-but I wouldn’t bet on that until you’ve checked everything else.
Symptoms of obd code P2014
If you’re rolling with a P2014, here’s what you’ll probably feel or see:
- Check engine light is almost a given-sometimes that’s your only hint.
- The engine might run rough, especially when you’re accelerating or cruising at certain speeds.
- You could notice a dip in power or sluggish throttle response, like your car’s lost its spark.
- Random engine misfires-little stutters or hiccups that make the ride less than smooth.
- Fuel economy taking a dive-if you’re filling up more than usual, this code could be the root cause.
Often, these problems start subtle-just a check engine light or a minor stumble. Ignore them, and you can bet they’ll get worse over time.
Diagnosis steps for dtc P2014
When I’m chasing down a P2014, here’s the process that’s worked for me time and time again:
- Start with a full scan for all codes. P2014 showing up alone is rare-there might be friends hiding in there.
- Give everything a good look-over. I’m talking about loose or broken wires, unplugged or cracked vacuum hoses, or anything odd around the intake manifold area.
- With the engine off, I’ll wiggle the wiring harness and connectors at the sensor and actuator. Sometimes just a little movement uncovers a loose pin or corrosion you’d miss otherwise.
- If nothing jumps out, it’s time to pull out the scan tool and watch the sensor readings while operating the actuator (if the scanner supports it). I’m looking for numbers that don’t match up with what’s physically happening-or signals that freeze or bounce all over the place.
- If I can get to it, I’ll try moving the runner valve by hand-sometimes it’s just stuck. Having a helper to work the controls while you watch the scanner can make this way easier.
- Vacuum lines are next. I’ll check every hose for cracks, leaks, or blockages. Don’t skip those tiny lines-they’re sneaky and easy to overlook.
- If all else fails, I’ll test the actuator and sensor circuits for voltage and continuity using the wiring diagram from the service manual. Only then do I start thinking about deeper electrical gremlins or computer problems.
Here’s a pro-tip: always rule out the easy stuff-wiring, hoses, connectors-before you start swapping parts or digging into advanced diagnostics.
Common Mistakes when fixing P2014 trouble code
I’ve seen plenty of people throw money and time at this code by making the same mistakes over and over:
- Bolt-on parts swapping-replacing the intake manifold or actuator without ever checking the wiring or vacuum lines first. That’s a fast track to frustration and empty pockets.
- Forgetting to clean a dirty throttle body-sometimes a good cleaning is all it takes to clear things up.
- Looking only at P2014 and ignoring other codes. You need the full picture before you start wrenching.
- Missing out on software updates or TSBs-a quick look at manufacturer bulletins can save you hours if there’s a known fix.
Don’t rush past the basics. A loose connector or tiny vacuum leak can mimic big problems, so always start small and work your way up.
Seriousness of P2014 code
P2014 isn’t a code you want to shrug off. Sure, your car might not leave you stranded in the driveway right away, but running with it can snowball into bigger, costlier issues. Poor performance and misfires put real stress on your catalytic converter, spark plugs, and even the engine itself. In my shop, I’ve seen folks ignore this code and end up needing major repairs that could’ve been avoided. If your engine starts running lean or misfiring too much, things can go sideways fast. Bottom line: don’t put this one on the back burner-get it checked out sooner rather than later.
Repair options for obd2 code P2014
After you’ve tracked down the real cause, here’s how I usually put a P2014 to bed:
- Swap out the intake manifold runner position sensor or actuator if they’re faulty-no point in patching what’s already toast.
- Repair or replace any wiring or connectors that are damaged, corroded, or loose. Good connections are everything.
- Give the throttle body and plates a deep clean or replace them if they’re sticking or grimed up.
- Chase down and fix any vacuum leaks-replace hoses that look old, cracked, or don’t fit right.
- If there’s a known software glitch, get the PCM updated or reprogrammed. It’s rare, but it happens.
- If all else fails and the mechanism inside the intake manifold is shot, replacing the whole assembly might be your only option-but save that for last.
Once I’ve wrapped up repairs, I always clear the code, take the car for a thorough test drive, and double-check everything’s running solid before calling it done.
Conclusion
Here’s the takeaway: P2014 means your intake manifold runner position system isn’t talking to the PCM the way it should, and that can really mess with how your engine runs. Don’t let this one slide-waiting only invites bigger headaches and steeper repair bills. Start simple: check your wiring, hoses, and connectors before diving into parts replacement. Nine times out of ten, a methodical, step-by-step approach will get you back on the road without drama. Move fast, fix it right, and your car-and your wallet-will thank you down the line.
