anyone else having trouble with this code. replaced stock air filter with aFe filter 10,000 miles ago. 20,000 on truck. threw code sunday dealer replaced filter with stock. said code may come back. which it did 5 miles later.

edge CTS says max boost is at 22 psi.

is this something i will live with or indication of something else?

 

You shouldn't have to live with a CEL over this.
Have you returned to the dealer after it threw the CEL with the stock setup?
Since it's now stock they need to troubleshoot it rather than tell you it may or may not return, IMHO.

I will say I have never seen my CTS show 22 PSI (stock filter).
I can get it to 21 PSI from time to time though.
Back before the CTS I used to think the gauge looked like 22 but the digital facts are better.

I'm sure you already know what this code is but for easy lookup by everyone else:
P2074 - Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load

 

i will call the dealer tomorrow see what they say.i had it looked at today and got my edge today.

i will say my boost gauge has moved to the right of the center mark and has that way for a little bit.

thanks for the advise

 

Follow Up; Turned out to be a bad mass air flow sensor.

Here is the read out from my Insight, must have been a one time thing.

 

Does the CTS always monitor max boost or did you have it recording?
I don't think I've ever been in the records screen on my device.

 

I just recieved and installed the CTS on Tuesday. I found that information under "records". I did an update of the software before I installed mine. Maybe it is in the update.

 

So what is the average cost on a MAF sensor? I'm sure that my extended warranty wont cover that at 52K miles? Any ideas?
