Technical Article: Diagnosing DTCs P0016 and P0018
If this Diagnostic Trouble Code (DTC) started after recent internal engine repairs, inspect for proper engine mechanical timing. With the camshaft cover removed and the #1 cylinder at top dead center, make sure that the darkened chain links are lined up with the alignment marks on the exhaust and intake cam sprockets.
If a P0016 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket.

Discuss the causes and fixes for P0016 GMC OBDII Code
-
I changed the cam and crank sensor on my 2007 yukon went to relearn crank sensor and code p0016 came right back one mech. Said his tech 2 says ign. Or injector fault but with live data saw any misses
-
How is the engine oil level and condition? how often do you change the engine oil? dirty or low engine oil could cause this problem.
-
Low or dirty oil can cause an improper operation of the cam phaser, which is what advance or retard the engine timing during certain engine operation.
-
on my 2007 yukon, i have the same problem, i changed the cam and crank senor, changed the oil pressure sensor because it was reading low oil everytime it idle. and the check engine still came on, i changed the oil. and nothing what else could be the problem?
