P0016 on a Chevy: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can often drive a Chevy a short distance with P0016, but if it runs rough, stalls, or won't start, stop driving — a jumped timing chain can cause major engine damage.

What P0016 means on a Chevy

On a Chevy, P0016 means the crankshaft and camshaft position sensors on bank 1 are reporting positions that do not line up. The two shafts are out of sync, which usually points to a stretched timing chain or a failing VVT phaser.

Is P0016 common on Chevys?

P0016 appears on Chevy models like the Silverado, Equinox, Malibu, and Tahoe. Timing chain stretch is more likely on high-mileage engines, and a failing VVT phaser or worn tensioner can also make the sensors disagree.

Commonly reported on: Silverado, Equinox, Malibu, Tahoe.

Symptoms

Check engine light on
Rough idle or stalling
Hard starting in some cases
Loss of power or poor fuel economy

Common causes

most common: Stretched or jumped timing chain
common: Failing VVT phaser
common: Worn timing chain tensioner or guides
less common: Faulty crankshaft or camshaft position sensor
less common: Low oil pressure affecting the VVT system

How to fix it

Fix	DIY?	Typical cost
Inspect the timing chain, tensioner, and phaser	Mechanic	$100–300
Replace the timing chain kit if it is stretched	Mechanic	$800–1800
Replace the VVT phaser if it is failing	Mechanic	$500–1500
Replace a faulty crankshaft or camshaft sensor	Yes	$100–300

Frequently asked questions

Is it safe to drive my Chevy with a P0016 code?

Short distances are usually okay if the engine runs fine. If it idles rough, stalls, or won't start, have it towed — a jumped timing chain can ruin the engine.

What causes P0016 on a Chevy?

A stretched or jumped timing chain is the most common cause at high mileage. A failing VVT phaser, worn tensioner, or faulty sensor can also set this code.

How much does it cost to fix P0016 on a Chevy?

A timing chain job usually runs $800–$1,800, and a VVT phaser adds more if it needs replacing. A sensor is cheaper, around $100–$300.
