First off:
2014 Cruze 1.8l LS
~66,000mi
K&N is the only "mod"

Recently got a CEL. Code P2076.

All of my interweb searches point to either MAF or TB Assembly. I called Dealer and they said neither would be covered under the powertrain warranty. Of course, he'd be glad to run diagnostics for $100. :$#angry:

So here the conundrum. Pay the dealer to "diagnose" the issue an then toss another $160 to replace the TB assembly and then possibly another $70 for the MAF? Those are my prices, not the dealer. Or just bite the bullet and replace them myself and pray that solves the problem?

has anyone had an issue with this code? I don't experience anything weird with the car and it's operation. I have reset the code and it has come back. Are their any other things I can do? I did clean the MAF, TB intake and seafoam'd the intake as well. Anything else?

i can't for the life of me figure out how the INTAKE CONTROLLER of an engine ISNT considered part of the "powertrain." Must be that GM voodoo logic. Lol

If the dealer follows normal practice the diagnostic charge is only applied if you choose not to perform the recommended repair.

Ask them for specifics.

Well. Had the dealer look at it. Good thing. I was looking at the wrong spot. The intake manifold tuning valve connecting rod (driver side of the intake assembly) disconnected due to being worn down in the ball end area. They replaced the whole intake manifold that day, without an appointment, and under warranty.

I'm happy now. Dealer exceeded all of my expectations.

This is becoming more common of a problem as the 1.8 engines age.

I figured. This is a ~$370 part (rock auto) and doesn't look like an easy swap. I figure this would take the shade tree mechanic at least 5hrs of work. This is provided that pulling or dropping the motor isn't required. Dealer said this part is $600ish from him so a dealer job would run close to $1k

I guess at this point I can only hope it dies at 99,9XXmi in order to get it replaced again at no cost. Lol

Im guessing if this valve is running wide open it shouldn't hinder the motor, just mpg?

I've been chasing a check-engine light on my 2013 Cruze. (My 2012 Cruze seems to be doing just fine.) Both are 1.8L (RPO LUW).

The two codes are P0496 and P2076. In the 2076 case, I found the link on the intake manifold tuning control valve had become separated from crank on the bottom end and re-inserted it. It has since come loose again, and I re-inserted it, but I can tell the fit is getting looser, so it will only be a matter of time before it pops out again <sigh>.

I think the car is out of warranty - the driver's door jamb indicates a born-on date of 2/13 - but I'll verify the status with the dealer Monday.

Anyway, assuming I need to repair this, besides replacing the intake, has anyone had success hacking a durable repair? It appears to me, with the right size fastener, the link and crank could be pinned together to effect a reliable repair. Has anyone tried that? Got any stories to share?

It does appear that hacking such a mod may require removing and re-installing the intake - several hours of work - but still ~$350 cheaper than the cost of an intake.

In that vein, has anyone seen an after-market repair kit for this? For example, Dorman sells a blend door replacement hack kit for my 1997 F-150. The instructions call for cutting open the heater box rather than disassembling the dash, a savings of ~8 hours labor. It's kinda ugly, but it worked very nicely and saved me a bunch of time.

I'd like to think there's a way of rigging an effective fix without replacing the intake. A kit with a new link and good instructions would surely be well received

BTW. I checked the rotation at the top, and it does not appear to be excessively sticky at the limits of travel.

Hi there,

I am having the same problem you had. I had the P2076 code pop up and in order for the dealership to tell me if the warranty would be able to cover it I needed them to run the diagnostic on it, which came out to 140$. Diagnostic came up with that the intake manifold tuning arm had sheared off outside the engine and would not be able to be covered by any warranties. However to me the tunning arm looks in good condition and just need to be placed back on.

If you don’t mind me asking, what warranty did they cover the replacement under?

Best Regards

At 66K miles, @AzSandSlinger would’ve been covered under 100K powertrain warranty as the 35K Bumper to Bumper warranty would’ve already been expired.

 

[Handymanny]

@Rivergoer I’m at approximately 56,000. Like you said, I’m expired warranty on bumper to bumper but still good on my powertrain. However the dealer said the powertrain warranty would not cover it ?

If your diagnosis is the same, it should be covered the same.

Maybe try another dealer if possible?

 

[Rivergoer]

Another option would be to contact GM Customer Assistance 866-790-5700. (Note: this number may vary by state, I’ve been given both 5700 and 5600 depending on if California or Arizona. If the number is different for your area, you’ll be transferred to the correct jurisdiction)

A case manager will be assigned to review your claim to determine whether warranty applies.

I’m hoping @AzSandSlinger replies with saying which warranty covered the repair. If it is the powertrain warranty, the dealership has some explaining to do.

Thank you so much

Yes, it was covered under the 5yr/100kmi Powertrain Warranty (this changed to 60kmi for 2016+ BTW)

That “part” is listed on page 26 of the new warranty book. Link below.

Hope this helps.

@AzSandSlinger and @Rivergoer Thank you very much.

Took in my Cruze and asked to speak to the supervisor. Explained to him how the part is referred to in warranty book. He then stepped away to confer with his technician. Who originally told me the IMT Valve would not be covered. When he came back after talking with the technician he then explained to me that the problem was not with the warranty, but that it had been damaged from outside source (i.e. a rock) according to the technician. I don't know how he knows a rock hit it and damaged it, because I was able to reattach the tuning valve and Is working 100 miles in counting. I believe it came unattached due to wear and tear. After telling him that the part been working, he then asked me to schedule appointment to have the Intake Manifold replaced with a refund of the diagnostic fee.

Best Regards
