P0016 on a Lexus: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can often drive a Lexus 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 Lexus

On a Lexus, P0016 means the crankshaft and camshaft position sensors on bank 1 are reporting positions that don't line up. Lexus engines use the VVT-i variable valve timing system, and a correlation code usually points to a stretched timing chain, a clogged oil control valve, or a faulty sensor.

Is P0016 common on Lexuss?

P0016 appears on Lexus models like the ES, RX, and IS at higher mileage. VVT-i oil control valves can get clogged with sludge, and timing chains stretch over time, though Lexus engines generally last a long time with regular oil changes.

Commonly reported on: ES, RX, IS, GS.

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
common: Clogged oil control valve
common: Worn chain tensioner
less common: Faulty camshaft position sensor
less common: Low oil pressure

How to fix it

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

Replacing the oil control valve runs about $100–$300. A timing chain job usually costs $1,000–$2,000, and a camshaft sensor is around $100–$250.
