P0016 on a Subaru: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can often drive a Subaru short distances 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 Subaru

On a Subaru, P0016 means the crankshaft and camshaft position sensors on bank 1 don't line up. Subaru boxer engines use the AVCS variable valve timing system, which runs on engine oil pressure, so this code often points to low oil pressure, a clogged AVCS solenoid, or a stretched timing chain.

Is P0016 common on Subarus?

P0016 is seen on Subaru models like the Outback, Forester, and Impreza. The AVCS solenoids and timing chains are sensitive to low oil levels and dirty oil, so neglected maintenance is a common trigger.

Commonly reported on: Outback, Forester, Impreza, Legacy.

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: Low oil level or low oil pressure
common: Clogged AVCS solenoid
common: Stretched or jumped timing chain
less common: Faulty camshaft position sensor
less common: Worn chain guide

How to fix it

Fix	DIY?	Typical cost
Check and top off the engine oil, and change it if it is dirty	Yes	$30–80
Replace a clogged AVCS solenoid	Yes	$150–400
Replace the timing chain kit if it is stretched	Mechanic	$1200–2500
Replace a faulty camshaft position sensor	Yes	$100–250

Frequently asked questions

Can I keep driving my Subaru with a P0016 code?

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

What causes P0016 on a Subaru?

Low oil level or low oil pressure is a common trigger because the AVCS system runs on oil pressure. A clogged AVCS solenoid or a stretched timing chain can also set this code.

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

An oil change is cheapest, around $30–$80. An AVCS solenoid costs about $150–$400, while a timing chain job usually runs $1,200–$2,500.
