OBD-II Code P0014 — What It Means & How to Fix It

What Does This Error Mean?

P0014 means the exhaust camshaft timing on Bank 1 is too far advanced. Your engine's computer detected the exhaust cam moved ahead of its target position. This throws off the precise timing needed for clean, efficient combustion. Dirty oil, a stuck solenoid, or a worn timing chain are the usual suspects. You may notice rough idle, stalling, or poor gas mileage.

Affected Models

All vehicles 1996+
Common in Chevrolet Equinox
Common in GMC Terrain
Common in Cadillac SRX
Common in Saturn Vue

Common Causes

Dirty or old engine oil causing sludge in the oil control valve passages
Exhaust camshaft actuator solenoid stuck in the open or advanced position
Worn or stretched timing chain allowing the exhaust cam to shift position
Low engine oil level starving the actuator of proper hydraulic pressure
Clogged oil screen filter on the actuator solenoid blocking oil flow

How to Fix It

Start with an oil level and condition check. Pull the dipstick and look at the color and consistency. If the oil is dark, gritty, or past its change interval, do a full oil and filter change.

Use the exact oil viscosity from your owner's manual. Wrong oil weight is a common trigger for this code.
Locate the exhaust camshaft position actuator solenoid on Bank 1. It's typically on the exhaust side of the cylinder head, closer to the back of the engine.

Don't confuse it with the intake solenoid, which is usually on the front or top of the head.
Remove the solenoid and inspect the mesh screen on its tip. A clogged screen blocks oil flow and causes the actuator to stick. Clean it thoroughly with brake cleaner.

If the screen is heavily clogged with sludge, consider doing an engine flush before installing the new solenoid.
Replace the exhaust camshaft actuator solenoid if cleaning didn't resolve the issue. Install the new part, tighten the bolts to spec, and reconnect the electrical connector.

The part costs $25-$90 at most auto parts stores. It's usually a 20-minute job with basic tools.
Clear the code using an OBD-II scanner and test drive the vehicle for several days. Pay attention to idle quality and any returning check engine light.

Most auto parts stores will lend you a scanner for free. Keep driving normally to let the system retest itself.

When to Call a Professional

If an oil change and new solenoid don't clear the code, take it to a mechanic. A stretched timing chain needs professional tools and expertise to replace. The mechanic can use a scan tool to test actuator response in real time. Diagnosis costs around $100-$200. Timing chain replacement runs $500-$1,500 depending on your vehicle.

Frequently Asked Questions

What's the difference between P0013 and P0014?

P0013 means there's an electrical circuit problem with the exhaust camshaft actuator. P0014 means the exhaust camshaft timing is physically too far advanced. P0013 is usually a wiring or connector issue. P0014 is usually an oil flow or mechanical issue. The solenoid replacement fixes both in many cases.

Can a P0014 code cause my car to stall?

Yes, in some cases the engine may stall at idle. When exhaust timing is too advanced, combustion efficiency drops. The engine may struggle to maintain a smooth idle. This is more likely when the engine is cold. Getting it fixed promptly prevents stalling in traffic.

How often should I change my oil to prevent this code?

Follow your owner's manual for recommended oil change intervals. Most modern cars need an oil change every 5,000 to 7,500 miles. If you drive in heavy traffic or extreme heat, change it more often. Regular oil changes are the single best way to prevent camshaft timing codes. Never go more than a year between oil changes, even with low mileage.
