P0016 on a Chevrolet Equinox
P0016 means crankshaft/Camshaft Position Correlation (Bank 1 Sensor A). On the Equinox, a few causes come up far more than others.
What P0016 usually means on a Equinox
On the Equinox, P0016 (crankshaft-to-camshaft correlation, bank 1) is closely tied to the 2.4L Ecotec's well-documented timing chain problems. These engines are known for both heavy oil consumption and timing chain stretch, and the two feed each other: low, dirty oil accelerates chain and guide wear, the chain stretches, and cam timing slips out of correlation with the crank. A rattle at start-up and this code together are the classic 2.4 Ecotec story. It is a code to address promptly, because a badly stretched chain can eventually jump time.
Most common causes on the Equinox
- Stretched timing chain (2.4L Ecotec)
The signature Equinox P0016 cause. The 2.4's chain stretches with mileage and oil neglect, retarding cam timing until the correlation error sets. A cold-start rattle usually accompanies it.
- Oil consumption starving the timing system
The 2.4 Ecotec's chronic oil burning leaves the chain and tensioner running on low, dirty oil, which accelerates stretch and can throw the code. Chain problems and oil consumption go hand in hand on these engines.
- Worn chain guides and tensioner
The plastic guides wear and the tensioner loses its ability to keep the chain taut, allowing slack that shifts cam timing and sets P0016.
- Stuck cam actuator/phaser or solenoid
A sludge-bound cam phaser or its oil control solenoid can hold cam timing off target, producing a correlation code before the chain is fully worn.
What P0016 costs to fix on a Equinox
P0016 on a 2.4 Ecotec rarely ends cheaply, because it usually means the timing chain, guides, tensioner, and often the cam actuators all need replacing as a set. That is a labor-intensive front-of-engine job commonly running into four figures. It is compounded by the oil-consumption problem, so a chain job on an engine still burning oil should be paired with a plan for the consumption or the wear will return.
Fixing it
Do not just clear P0016 and keep driving, since a stretched chain can jump time and cause damage. Replace the full timing kit and cam actuators, check oil consumption, and keep oil topped off and changed on time afterward.

Year, engine and mileage change the answer. Start a case and Redline weighs these causes against what your car shows, then names the check that would settle it.
Equinox owners also ask
Is the timing chain a common problem on the 2.4 Equinox?
It is. The 2.4L Ecotec is well known for timing chain stretch, and it is closely linked to the engine's heavy oil consumption, since running low on oil accelerates chain and guide wear. A start-up rattle with P0016 is the classic sign.
Why is oil consumption connected to the timing chain?
The 2.4 Ecotec burns oil, and if the level drops between changes the timing chain and tensioner run on insufficient, dirty oil, which speeds up stretch. Fixing the chain without addressing consumption invites the problem to come back.
