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 Subject: Models: Service Bullet,in PRELIMINARY INFORMATI01 N Code P06DD No Or Low Oil Pressure 2016 Cadillac CTS-V 2015-2016 Cadillac Escalade 2016 Chevrolet Camaro 2014-2016 Chevrolet Corvette 2014-2016 Chevrolet Silverado 2015-2016 Chevrolet Suburban, Tahoe 2014-2016 GMC Sierra 2015-2016 GMC Yukon XL Built with RPO's 4.3L 5.3L 6.2L L83 L86 L T1 LT4 LV3 The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this Pl.
