U2609. Truck running goofy.

[armynavyguy]

I changed my CCV last week. Since then I still get a P1507, P1508 and a U2609. Why would I still be getting CCV codes if I just changed the filter? And the U2609 is related to the grid heater. I don't understand why the grid heater would be running goofy if I barely use it. H&S said since I have a CAI that could be the problem. I don't understand how. Truck runs fine above 1500 rpm. But for the past two weeks there white smoke at start up in the morning. It's seems to idle a little rough and it's sluggish or stuttures a bit below 1500. Any help would be greatly appreciated.

Go out to your truck and tell me if you plugged the sensor back in that threads into the Plenum cover between the rail and valve cover.

Ok. I don't recall unplugging any sensors but once I get out of school I'll check. Thanks. Would it hurt or help if I disconnected the batteries overnight to reset the ECM? Just throwing it out there.

depending on the conditions for latching those codes unplugging the battery will likely do nothing. Something was bumped/unplugged/damaged/pinched when you did the filter, as those codes would likely not present themselves otherwise.

Did you get the filter seated properly? (I think it is difficult to not install it right, but you may want to check an o ring didn't get nicked. did you get the tube properly seated back into the air intake tube just before the turbo? did you get it seated back onto the top of the valve cover?

I don't have good definitions of what those two codes are, but if they are MAF related, having air pulled in through an open hose, like the one from the CCV outlet, would cause codes to activate because it'd sense the air velocity by the MAF is too low.

I did recheck the o ring earlier this week and it was fine. I checked the sensors at lunch and they are fine as well. I'll recheck the tube that comes off the CCV at make sure everything there is in good condition and installed correctly.
