High Voltage Issue?? EBS, TPS and Windshield wiper interval come on screen under hard acceleration after intake install

[sxottsdale]

I'll keep it as short as I can-

I installed the AFE intakes on my stinger and when I started driving after install, a bunch of lights came on (EBS, AUTO HOLD, Tire Pressure) but not CEL. They immediately went away.

Then under harder acceleration the the screen told me to check tire pressure, went away(happened multiple times but not every time)
Then shows me the windshield wiper interval but I didn't have them on or touch it.
Also my Escort Max360c have me a warning about "High Voltage".
Each time hard accelerating less weird lights happened.

Parked the car and walked away but tried to lock it with no response. Got in the car and nothing was on or responsive. Got out closed the door and it responded to lock and 15 min later is fine locking and unlocking.

Anybody got any idea tf is going on? Does the car just need to get use to the intakes?

Something went wrong. Must have disconnected some wires, or broken them, or something.

 

[sxottsdale]

I would agree- but I checked everything and all connections and wires even remotely close look perfect. And the issue is now isolated to WOT creating a high voltage reading on my radar detector then the car cuts out all electricity. But drove it today without gassing it and it was perfect. Probably going to take it to a performance shop to replicate on a dyno and test all the voltages.

Checking it on a dyno may not replicate the problem. The car may need to be actually moving/acceleratiNg if it is caused by something moving under hard acceleration.

Driving it home it threw p0016 and p0018.

Those are related to cam/crank position sensing.
Sounds like weird electrical gremlins, any chance the battery is going out, or possibly rodent wiring damage?

What did you unplug during installation? Did the problem onset immediately after install?
Could be a battery or wiring issue unrelated, but I don't really believe in coincidence.

 

[sxottsdale]

Unfortunately nothing was unplugged during installation and all the wiring harnesses look fine from what I've checked and was hoping to just see a nicked wire or half plugged in sensor but nothing. The weird part is the cam/cranks sensors are on the back of the block so literally could not be further from the intake installation spot. I'm leaning more toward the idea that this is a battery or alternator issue but I would agree that there is no such thing as a coincidence. And yes the problems onset immediately after install so I'd be a fool to assume I didn't do something.

Theres a tune and engine performance shop here in Scottsdale I went over to this morning. They said they've work on countless stingers and they use these AFE intakes all the time on our cars. They said it's most likely its an electrical short, general wire harness issue or even could be engine oil issues. If its not that, they said its possible the cam chain skipped a tooth but theyve never seen that on these cars. They told me to take it to the dealership because either I bumped/nicked a harness and not a big deal or its completely unrelated and would be under warranty. But if the dealership just blames the intakes they'd be happy to take it over from there and fix it.

So you didn't touch the battery, correct?
Check the ground wire in the trunk first, make sure it isn't loose or anything like that, then check the rest of the battery connections.
The symptoms certainly resemble a battery or voltage regulation issue.
It is highly unlikely the systems for the codes you are getting actually have anything wrong with them. I'm leaning towards battery/connections. Body control unit is another possibility, maybe, but that's quite remote.

Also, you mentioned a radar detector, where is the powered tapped into for it? Do you have other accessories installed?

Is there a ground connection in the area of the intakes? If there is, check the wiring in that area and make sure the nut is tight.

Correct, didn't touch the batter and previously my ground wire nut cam loose and the car would cut out but I checked that this time and it was secure.
The radar detector is plugged into the cigarette lighter with the escort smart cord.

With talking to the shop this morning and y'all I'm leaning the same way. Just completely bizarre that this was an immediate problem after the intake installation. I'm more convinced I have to have done something to a harness but just can't imagine how. Maybe pushed the engine cover down onto the cam sensor when putting it back? but also weird because those codes are throwing for both sensors not just one.

If there is I have no idea about it and am not seeing it on google

 

[AdrianG]

Do you leave your radar detector plugged in all the time? As in, is it on while the car is off?
My advice would be to stop thinking it is a problem with the sensor or connection to it. If it were, the symptoms would probably be isolated, but they clearly are not.
Your symptoms indicate a power supply issue. Usually if it is an alternator problem, your battery will die rather quickly and the vehicle will likely recognize a charging system issue.
It is probably a bad battery or a poor connection somewhere.
While I don't really believe in coincidence, if you didn't actually touch anything in the electrical system while doing the intakes, then something else caused your problem at the same time.

The detector stays plugged in but with the smart cord it doesnt pull power until the car is turned on and it turns off the second my car turns off.

I've got an appointment monday so I'll update this thread

Still don’t have the car back, dealership says they’ve narrowed it down to electrical issue that they can’t pin point. As of yesterday they asked me if they could do a long test drive to gather data for Kia engineers, which they sent over last night and should hear back today or tomorrow.

I’ve been driving my wife's expedition and she wants it back- told me to go get an Audi s5 and sell the stinger when they fix it, so I guess it hasn’t all been bad

Narrowed it down??

didn't we all know from the first post it was an "electrical issue"?

that's not very narrow - lol.

Laser focussed like a flood light.

 

[AdrianG]

"We've narrowed it down to being some sort of issue with the car"

 

[sxottsdale]

I called them yesterday to ask for an update. They said they recorded the data incorrectly and the files wouldn’t open for the Kia engineers so they were recordin it again and sending it off…
Just expecting my car to come back with 5k more miles and then be back in the shop a week later

Stumbled back upon this thread after a long time- I didn't end up getting my Stinger back until late April and then late June. During that time the following happened.

Mid April-dealership "identified" a battery issue cause by faulty sensors. replaced both, cleared codes and told me to pick it up.
2 days later- car goes into limp mode under first WOT since getting the car back. turned the car off and then back on threw=p0016 and p0018 codes again. Took the car back in.
late May- After them not knowing wtf was happening and telling me "we're working with corporate kia engineers directly and waiting on them" dealership identified an with the crankshaft. ordered parts under warranty.
Early June- They finished install and went to make sure everything was fine before i picked up the car the next day. Got a call that the engine wouldnt hold oil pressure. "We'll let you know"- They decided to replace the whole engine.
Late June- got the car back with a brand new block and the dealer installed the AFE Intakes back with the new block. Had the Stinger back for 20 minutes which was the drive from the Kia Dealership to the Ford dealership and bought an Explorer ST high performance pack that they had just gotten in.

All in all it was a hell of a 4 month journey.

A failed crankshaft install leading to a new engine, which all started from a failed intake install... WTF
