P0016 — Crank/Cam Correlation Fault (Bank 1 Intake)

P0016 is set when the ECM compares the relative timing of the crankshaft and Bank 1 intake camshaft sensors and finds them more than a calibrated number of degrees out of alignment. This almost always means one of three things: the timing chain or belt has stretched or jumped, the cam phaser is mechanically stuck, or one of the position sensors is producing a bad signal. P0016 is one of the strongest early indicators of timing chain wear on modern engines.
