P0016 on a Nissan: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can often drive a Nissan 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 Nissan

On a Nissan, 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 worn timing components.

Is P0016 common on Nissans?

P0016 shows up on Nissan VQ V6 engines in the Altima, Maxima, and Pathfinder, where timing chain stretch is a known issue at higher mileage. A worn chain tensioner or a faulty sensor can also set this code.

Commonly reported on: Altima, Maxima, Pathfinder, Quest.

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 timing chain (VQ engines)
common: Worn timing chain tensioner
less common: Faulty crankshaft or camshaft position sensor
less common: Low oil pressure affecting the VVT system
less common: Worn VVT actuator

How to fix it

Fix	DIY?	Typical cost
Inspect the timing chain and tensioner	Mechanic	$100–300
Replace the timing chain kit if it is stretched	Mechanic	$1000–2200
Replace a faulty crankshaft or camshaft sensor	Yes	$100–300
Have oil pressure checked if the code returns	Mechanic	$100–250

Frequently asked questions

Is it safe to drive my Nissan 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 Nissan?

Timing chain stretch is a known issue on VQ V6 engines at higher mileage. Worn tensioners and faulty sensors can also set this code.

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

A timing chain job on a V6 usually runs $1,000–$2,200. Replacing a sensor is much cheaper, around $100–$300.
