Issues After HG Repair
Hey Guys,
Did a job for a customer and he's completely satisfied. Heres what I did:
ARP Studs
OEM Gaskets
Heads Were Decked, Valve Job Done, Seats Replaced (Cracked), Couple Valves and Guides Replaced as well, Pressure tested Magna Fluxed etc.
Power Max Turbo
EGR Cooler Deleted
Tuned By Gear Head Automotive
The customer has been driving the truck for 2 weeks and all was well...until yesterday. He called and said it threw a MAF code (P0069) which doesn't make sense to me, and then it had no boost. Its coming in tomorrow, just trying to go through in my head what the possibilities could be. I'm hoping its something simple like I forgot to slide the clamp back on to the MAF vaccum line, but something tells me its not going to work that way for me.
So Give me some insight on what you all think. I will post up tomorrow once I have a look at the truck, and I'm hoping I just made a simple mistake.
BTW its an 05 with about 130k on it...I did look over the flex joints on the exhaust real good and I saw no cracks or soot on the joints...not to say I didn't cause a leak.

Hopefully not a stuck turbo...its brand new.
I didn't think of the EBP sensor either...I suppose that the tube could be plugged as well considering I did all that work I will run a pipe cleaner through it if I can get the senor off, Like I said hopefully its simple, but I haven't run into this after doing this type of repair before.

I'm going to say you miffed a wire connection.....
pretty coincidental. Return the truck to stock if those were new tunes before you tear into it. Programs go stupid sometimes.

I hope your right max,
I always beat myself up when things come back...thinking the worst first. I always try to be super careful and treat everyones car like it was my own.
The truck was running awesome for 2 weeks on the tunes as well so Im not so sure that's it but I can return it to stock and see if it makes a difference.

Not sure what the issue was, but the truck checked out. He actually called me the following day and said the truck was running great with no issues, so I looked it over and couldn't find anything wrong with it.
Maybe just had some debris in the EBP tube that threw the sensor off....I have no explanation I guess, but the truck runs awesome and the customer is happy.

I was on a test drive once after a repair,, horrible boost!!!! I did forget to attach the MAP hose to the intake. I pulled over, put the map hose on,,, and it was all good. So yes, if the map hose gets blown off,,, it will cause the truck to run horrible. Glad it worked out Sarge..

Well the CEL came back on with the P0069. Checked all my hoses and connections all looked good, test drove the truck and it was fine. Im thinking maybe the EBP sensor is bad or possibly has some carbon built up in the tube.
Anyway I guess Im grabbing at straws here, but I couldn't find anything simple that I would have messed up.
So I cleared the code, reset the KAM, drove it again and it ran great.
Crossing my fingers but I think it will be back. At that point I will remove the EBP sensor, clean the tube, and put a new sensor on it. Maybe I will swap my MAP sensor with his and see if that helps as well. Not trying to throw parts at this thing but all my data looks good...atleast when the truck is here.

Exactly^^^
The DTC is triggered from BARO-MAP sensor reading
But lots can trigger as Moe mentions here
that if you compare BARO & MAP at KOEO and they good its likely something other then those sensors, BUT Drive it see if one of them gets way whacked out
I will add
Might be worth a air test of the CAC System
Leaking intake manifold gasket
Plugged exhaust
Exhaust plugged is probably a Long shot you should see with EBP reading

I doubt its a plugged exhaust too Benny. I had this truck torn down and thought I did a good enough job of inspecting everything, but I guess I over looked something. Not sure about the intake gaskets as a possibility either as I did install new 1's when I had it apart, I would think that if they were leaking it wouldn't be so intermittent either.
Could be that its just a bad sensor that Im not picking up while its here, it does have about 140k on it.
I will look at the MAP/BARO again when it comes back in...if it does, and make sure that they read fairly close with the KOEO.
