So \i'm at a loss... Cam sensor problems.

[Krace]

I did a pull on a open road and the car popped codes p0365, p0369 and p0390, p0394. Car idles rough and sounds like it has a ghost cam tune. I've tried a lot of things to help narrow it down, but im coming up short on what can be causing it....
Some of the things i have tried are reinstalling tune,checking for vacuum leaks/boost leaks, pulled and checked the cam exhaust sensors (replaced them anyway), checked cam sensor wires to ECU, checked fuses, alternator had bad diodes so it was replaced and battery is new as of now.
If i unplug the cam sensors (exhaust side is B i think) i don't have a change in idle or sound. Also if i clear codes they just come back with in seconds.

2014 Mustang GT auto 14k miles

Codes:
P0365 Camshaft Position Sensor B Circuit Bank 1
P0369 Camshaft Position Sensor B Circuit Intermittent Bank 1
P0390 Camshaft Position Sensor B Circuit Bank 2
P0394 Camshaft Position Sensor B Circuit Intermittent Bank 2

My Mod list:
Circle D 3c Convertor
2 Relay Trans-brake Mod
MSD 2 Step
Paxton Novi 2200sl 10.5psi
Kooks mid length Headers
3" off road X pipe dumped
E85, ID1000s, JMS BAP 20v
TSS tuned

Any help will be appreciated!

Have you talked to your tuner? That would be my first course of action. I wouldn't rule out a possible issue with the crankshaft position sensor either.

Naw i have not , the car has been running on the same tune for 2 years now and it's been flawless. Not much they can do in a different state. Something broke on the car that was sudden. I'm willing to guess its electrical or mechanical, not tune related in anyway. I'll have to take a look at the crankshaft sensor too i guess, even though the trouble codes don't mention it.
Thank you for the suggestion.

I also going to go ahead and replace the intake cam sensors and check the wiring to them as well, to rule them out.

phaser could have failed, or solenoid. i'd start by replacing the 2 solenoids on that bank, just as a precaution. they are much cheaper than the phaser's... also check the wiring, may have failed.

Curious to hear what happened. Have you fixed the issue?

Kinda hard for me to type out how i came to the concussion. But in the end, i found out it skipped timing from warndown teeth on the crank timing sprocket.

Holy cow was it a busted tooth? or did the chain stretch out from the crazy surging on the valvetrain?

Your car has 14k miles and the teeth were worn down? Any chance you have a pic of the sprocket, id like to see how its worn causing it to skip. Thanks.

 

[Krace]

working on getting a pic soon.

also i was not kind to this motor, thats 14k of racing it has done (rolls digs street and track). 13k miles has been boosted ( on e85 only).

 

[clinton2003]

be sure to replace your tensioners, wondering if one of those failed causing the excessive wear/skipping. maybe got low on oil pressure? idk

 

[twistedneck]

Is it me or do I see a trend of extra wear on the chains and tensioners and sprockets with supercharged setups?

 

[Reaper14]

This was mine at 25k mi before I boosted. I felt like it should not have that much wear at that milage, but it did.

[twistedneck]

That is telling. A huge amount of wear fOr NA only that means mine must be smoked i have 36k miles.

Do u think its a coyote trait? Was this typical on mod motors i wonder?

 

[Reaper14]

I dont know, but it makes me wonder how many miles I should go before I change it again later. I know the new one is billet, but it is also boosted now.

[Krace]

this is what happened, it jumped the keyway.

 

[Reaper14]

It jumped the keyway & some

[clinton2003]

Damn John, you got lucky. be sure to replace most of your timing stuff. Better safe than sorry.

 

[SHIFTYBUSINESS]

Wow, pretty crazy broke the crank gear. Yeah I would replace all of the timing parts for piece of mind. Good time to go billet opg's as well.

Yeah I plan on doing opgs and sprocket gear. My question now is how likely that I did not bend the vavles?

I'm pretty sure it's a non interference engine. Call mmr they ask them real quick.
