P06DD code

[BArriaga8]

I have a 2014 silverado 1500  with a 5.3l, I have the P06DD code, does anybody have any actual solutions for this problem? I have been searching and no one has seemed to actually found a definite reason for this code or solution. Any help would be greatly appreciated.

Oil pump seems to be the actual failure. It's behind the timing cover.

Mine had the same problem. It’s the engine oil pressure switch gauge. It’s like 50$ part from online, which you want to make sure the kit includes the sensor AND the filter screen for it, otherwise you’ll get the same code in no time. The worst part is the labor for it. It’s from build up of carbon in the engine that “gunks” up the oil and gets trapped on the filter sending a code for “stuck in off position”. I looked around and older GM’s you could have done the labor yourself though kinda tough. The 14 like I have, it just so happens to be inside the engine, right below the headers somewhere, which only makes the labor that much more expensive. Overall I’d look around at pricing on replacing the sensor and filter. Bulk of price is almost completely labor related. Mine would come on and off, once I did some work on the truck luckily it just so happened to free up and now is never on. Most people with this problem will see their check engine light come on and off(on more often than off). Hope this could get some insight.

I found 14 TSB's related to that code...Are you having any other conditions or codes at the same time? A little more information might help the folks on the forum here to think about what your problem is...

I have the 14 and am right at 133,000 miles and just recently got this code, it is off now.  2 fill ups ago I used a fuel additive (STP type stuff) which I have never done prior to this.  From reading these comments, I am thinking that possibly the additive cleaned up some of the carbon build up and has caused the "gunk" to get trapped on the filter and may have triggered the code.  Is this possible or more of an unrelated coincidence???

I have a 2014 with the code P06DD.  Had the vehicle serviced twice to clean it up and replace oil sensor. The P06DD is still showing. After some searching I discovered SB-10080702-2280  https://static.nhtsa.gov/odi/tsbs/2016/SB-10080702-2280.pdf

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this Pl.

Condition/Concern Bulletin No.: PIP5407

Date: Jun-2016 Vehicle setting code P06DD, no or low oil pressure, oil control valve may be stuck off commanding high oil pressures (95 psi) and or oil pump face may be damaged.

Recommendation/Instructions Tensioner spring in timing chain guide may be "short" not fully seating into guide pivot end. Cycling Oil Pump Control Valve will not cause changes in oil pump response.

1) Short spring not reaching the pivot. Replace timing chain tensioner guide. If oil pump face is damaged and or worn thru replace oil pump. Inspect bearings for damage wear due to debris from oilTensioner spring in timing chain guide may be "short" not fully seating into guide pivot end.  

This is a major issue with a very large repair bill of $1500 to $2000 USD.
