P0014
Fix within a few daysThe engine's computer detects that the exhaust camshaft on Bank 1 is too far advanced or not performing as expected.
Code P0014 means your exhaust camshaft on Bank 1 is over-advanced. Common causes: VVT solenoid (70%), dirty oil (15%), camshaft phaser (10%). Drivability: Yes, for short trips, but fix quickly. Repair cost: $50-$200 DIY, $150-$500 professional.

Common Causes of P0014
Parts most likely causing this code, ranked by probability
A faulty or clogged VVT solenoid prevents proper oil flow to the camshaft phaser, causing incorrect timing.
70% of P0014 cases are fixed by replacing this part
The VVT system relies on clean engine oil at the correct pressure to operate the camshaft phaser effectively.
15% of P0014 cases are fixed by addressing oil level or quality
The mechanical component that adjusts the camshaft position can fail internally, even if the solenoid is working.
10% of P0014 cases are fixed by replacing this part
Damaged wiring or a loose connector to the VVT solenoid or camshaft position sensor can cause incorrect signals.
4% of P0014 cases are fixed by repairing electrical connections
A rare internal fault in the engine's computer can incorrectly command or interpret VVT system operation.
1% of P0014 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Verify engine oil level is full and the oil is clean, not sludgy. Low or dirty oil is a common cause.
- Inspect the electrical connector to the VVT solenoid for any looseness, corrosion, or damage.
How to Diagnose P0014
- 1Check engine oil level and condition; ensure it's full and clean.
- 2Inspect the VVT solenoid (Oil Control Valve) for visible damage or oil leaks.
- 3Test the VVT solenoid's electrical resistance and operation using a multimeter and 12V power source.
- 4Inspect wiring and connectors to the VVT solenoid and camshaft position sensor for damage or corrosion.
- 5Use a scan tool to monitor camshaft position sensor readings and VVT solenoid command/actual values.
- 6If all else checks out, consider a faulty camshaft phaser or internal engine issue.
P0014 on Popular Vehicles
Chevrolet Silverado
2007-2024Commonly seen on V8 engines. Often linked to VVT solenoid failure due to sludge buildup from irregular oil changes. Sometimes the camshaft position sensor or camshaft phaser can also be the culprit.
75% fixed by VVT solenoid or oil change
Honda Accord
2003-2024P0014 on Honda Accord models (especially 4-cylinder) often points to a clogged or faulty VTEC/VVT oil control valve or screen. Ensure proper oil level and use the correct oil viscosity.
70% fixed by VVT solenoid or oil change
Toyota Camry
2007-2024For Toyota Camry, P0014 typically indicates an issue with the VVT-i oil control valve (solenoid) on the exhaust side. Sludge from infrequent oil changes is a known contributor to VVT-i system problems.

Frequently Asked Questions
What does P0014 mean?
P0014 indicates that your engine's computer has detected an issue with the exhaust camshaft timing on Bank 1, specifically that it's over-advanced or not performing correctly. This is usually related to the Variable Valve Timing (VVT) system.
Can I drive with P0014?
Yes, you can drive for short, essential trips, but fix this code quickly. Continued driving with P0014 can lead to reduced engine performance, poor fuel economy, and potentially more serious engine damage or catalytic converter failure over time.
Will P0014 clear itself?
No, P0014 will not clear itself. The underlying issue causing the incorrect camshaft timing must be repaired. Once the repair is made, you will need to clear the code with a scan tool, or it will clear after several drive cycles if the problem is resolved.
How do I fix P0014 myself?
Start by checking your engine oil level and condition. If the oil is good, the most common fix is replacing the VVT solenoid (Oil Control Valve) on Bank 1. This usually involves removing a single bolt and an electrical connector. If that doesn't work, further diagnosis of wiring or the camshaft phaser is needed.
How much does it cost to fix P0014?
If it's a VVT solenoid, the DIY cost is $50-$150 for the part. A professional repair for a VVT solenoid typically costs $150-$500, including parts and labor. If the camshaft phaser needs replacement, costs can be significantly higher, ranging from $500-$1500+ due to increased labor.
P0014 keeps coming back - why?
If P0014 keeps returning, it often means the initial repair didn't address the root cause. Common reasons include: persistent low or dirty engine oil, a faulty camshaft phaser (not just the solenoid), wiring issues, or a problem with the camshaft position sensor. A thorough diagnosis is essential.
Will P0014 fail emissions/smog test?
Yes, P0014 will cause your vehicle to fail an emissions or smog test. A Check Engine Light (CEL) illuminated for any reason is an automatic failure in most jurisdictions, and issues with valve timing directly impact emissions.
What's the difference between P0014 and P0011?
P0014 indicates an issue with the exhaust camshaft on Bank 1 being over-advanced. P0011 indicates an issue with the intake camshaft on Bank 1 being over-advanced. Both relate to the VVT system on Bank 1 but affect different camshafts.
P0014 on Chevrolet Silverado
On many Chevrolet Silverado models, especially those with V8 engines, P0014 is frequently caused by a failing or clogged VVT solenoid (Oil Control Valve). Neglected oil changes can contribute to this. Always check oil level and quality first, then inspect and test the VVT solenoid.
Questions to Ask Your Mechanic
Did you check the engine oil level and condition before diagnosing the VVT system?
Good answer: Yes, the first step was to confirm the oil was at the correct level and free of excessive sludge. This is critical for VVT operation.
What were the actual and commanded camshaft positions when you monitored them with the scan tool?
Good answer: I saw the commanded exhaust camshaft position was X degrees, but the actual position was Y degrees, indicating it was stuck or not responding correctly.
Did you test the VVT solenoid's electrical resistance and function before recommending replacement?
Good answer: Yes, I checked the resistance, and it was out of spec, or I applied 12V and confirmed it wasn't clicking or moving freely.

Intermediate - Replacing a VVT solenoid is manageable for someone with basic mechanical skills and tools, but diagnosing deeper issues like a camshaft phaser requires more advanced knowledge and diagnostic tools.
Cost of Waiting
Ignoring P0014 can lead to continued poor fuel economy, reduced engine power, and increased wear on engine components. Misfires caused by incorrect timing can send unburned fuel to your catalytic converter, potentially causing it to overheat and fail, turning a $100 solenoid job into a $1,200-$2,500 converter replacement.
While You're In There...
The VVT system relies heavily on clean engine oil. If your oil is dirty or low, replacing it along with the filter is a critical first step and good maintenance.
These often come with a new solenoid, but if not, replace them to prevent oil leaks and ensure a proper seal.
Tools You'll Need
- Basic hand tools (sockets, wrenches)
- Multimeter
- OBD-II scan tool
- Oil drain pan (if changing oil)
- Torque wrench
P0014 is a common engine code related to your vehicle's variable valve timing system. Most repairs are straightforward, often just replacing a VVT solenoid, and your engine will run smoothly again.

Your Next Steps
Step 1: Check your engine oil. Ensure it's at the correct level and clean. If it's dirty or low, change the oil and filter, then clear the code and retest.
Step 2: If the oil is good, locate the exhaust VVT solenoid on Bank 1. Inspect its wiring and connector. Disconnect it and test its resistance with a multimeter. Compare to factory specifications.
Step 3: If the solenoid tests bad or looks suspicious, replace it. This is the most common fix. You'll likely need a new VVT solenoid (Oil Control Valve) and possibly a new gasket or O-ring.
