P0014: B Camshaft Position - Timing Over-Advanced Or System Performance
P0014 means the engine computer sees the B camshaft timing too far advanced, or the cam phaser is not responding the way it should. The most common fix is an oil and oil-control-system repair, which usually runs about $150 to $600, though cam phaser or timing parts can cost more.

What does P0014 mean?
This code points to a variable valve timing problem on the camshaft the computer calls “B,” which is usually the exhaust cam on many engines. The engine computer commands a certain cam timing angle, then checks whether the camshaft actually reaches and holds that angle. If the timing stays too advanced, moves too slowly, or does not match the command, P0014 sets. Low oil level, dirty oil, a sticking oil control valve, or a worn cam phaser are common reasons. In some cases, stretched timing components or an engine timing issue can cause the same code.
Common symptoms
- Check engine light on
- Rough idle
- Hesitation when accelerating
- Loss of power
- Poor fuel economy
- Rattling or ticking noise from the engine
Causes, fixes and costs
P0014: B Camshaft Position - Timing Over-Advanced Or System Performance
General guide for most cars. Your car may differ.
The car may still run, but the problem can hurt fuel economy, performance, and emissions, and in some cases lead to rough running or further engine damage. Stop driving if the engine starts knocking, stalls, loses power badly, or the oil pressure light comes on.
Most likely causes
- 1
Low or dirty engine oilHigh
If the light came on with rough idle, hesitation, or after an overdue oil change, bad oil is the first thing to check. Variable cam timing systems depend on clean oil at the right level and viscosity.
Quick check: Check the oil level and condition on the dipstick. If it is low, thick, sludgy, or very dirty, service the oil first and clear the code.
- 2
Faulty oil control valve or camshaft actuator solenoidHigh
A sticking or clogged solenoid often causes the cam timing to stay advanced, especially if the code returns after an oil change. Symptoms may come and go as the valve sticks.
Quick check: Listen for an abnormal ticking and inspect the solenoid and connector for oil contamination, damage, or corrosion. A scan tool can command the solenoid and compare the requested and actual cam angle.
- 3
Sticking or worn cam phaserMedium
If the code keeps coming back with a good oil supply and a working solenoid, the cam phaser may be mechanically stuck. This is more likely when there is startup rattle, chain noise, or persistent rough running.
Quick check: A mechanic can compare cam timing data with a scan tool and test whether the phaser responds correctly. Engine noise near the timing cover is another clue.
- 4
Timing chain stretch or timing component wearMedium
If the engine has high mileage, poor maintenance, or a chain rattle, the cam timing may be physically off instead of only electronically controlled. This can set P0014 along with drivability complaints.
Quick check: Look for rattling from the front of the engine, hard starting, or related cam/crank codes. A timing inspection is needed to confirm it.
Can you fix it yourself?
Possible with some experience
Difficulty: Moderate. Basic checks like oil level, oil condition, and connector inspection are DIY-friendly. Replacing the oil control valve is sometimes manageable with hand tools, but cam phaser or timing repairs usually need a workshop.
Show the stepsHide the steps
- Check the oil level and condition
- Change the oil and filter if overdue or dirty
- Inspect the camshaft actuator solenoid connector and wiring
- Clean or replace the oil control valve if it is accessible and tested bad
- Clear the code and road test the car
- If the code returns, have cam timing and phaser operation diagnosed
Estimated repair cost
$60 – $120
Oil change and correct filter: parts and labor
- Oil control valve / camshaft actuator solenoid$150 – $350
- Camshaft phaser$500 – $1,200
- Timing chain service$900 – $2,000
Prices vary by engine design, parts quality, and local labor rates.
Frequently asked questions
Can I drive with code P0014?
Usually yes for a short time if the car runs normally, but you should get it checked soon. If it starts knocking, stalling, running very rough, or the oil pressure light comes on, stop driving.
Will P0014 clear itself?
Sometimes the light may go off temporarily if the oil issue was minor, but the code usually comes back if the underlying problem is still there. The repair depends on whether the cause is oil service, a solenoid, a phaser, or timing wear.
Is P0014 caused by low oil?
Low oil or dirty oil is one of the most common causes. These systems use engine oil to move the cam phaser, so oil level and oil condition matter a lot.
Can a bad camshaft position sensor cause P0014?
Usually no, because P0014 is mainly about cam timing being too advanced or not responding correctly, not just a bad sensor signal. A sensor problem is more often tied to cam sensor circuit codes, though wiring issues can still confuse diagnosis.
How much does it cost to fix P0014?
A simple oil service may cost around $60 to $120, while a solenoid repair often falls between $150 and $350. If the cam phaser or timing chain is involved, the repair can climb to $500 to $2,000 or more.
