If your check engine light suddenly appears and your scanner reveals a P0014 code, don’t panic — but don’t ignore it either. This diagnostic trouble code (DTC) indicates a problem related to the camshaft position B timing being over-advanced or the system performance of the exhaust camshaft. Common in vehicles with variable valve timing (VVT), this issue can affect performance, emissions, and long-term engine health.
What Does the P0014 Code Mean?
The P0014 trouble code stands for “Camshaft Position B – Timing Over-Advanced or System Performance (Bank 1).” It refers to the exhaust camshaft on Bank 1, typically the side of the engine with cylinder 1.
When this timing is more advanced than expected, it can signal a malfunction with components like the camshaft actuator, control solenoid, or the engine oil itself — all of which are essential for proper VVT operation.
Common Vehicles Affected by Code P0014
- P0014 Chevy (especially Equinox, Malibu, Traverse)
- P0014 Hyundai (Sonata, Elantra, Tucson)
- Other vehicles with variable valve timing systems
Causes of P0014 Code
Several factors can trigger the P0014 code, including:
- Low or dirty engine oil
- Faulty camshaft actuator
- Damaged or shorted camshaft position sensor
- Defective control solenoid valve
- Issues with the engine control module (ECM) or powertrain control module (PCM)
- Worn or stretched timing chain or belt
A low oil level or incorrect oil viscosity can disrupt VVT operation, leading to advanced camshaft timing.
Symptoms of P0014 Error Code
When this code is active, you may experience:
- Check engine light illumination
- Rough idling
- Decreased fuel efficiency
- Poor acceleration
- Engine hesitation or stalling
- Hard starts
How to Fix the P0014 Code
Here’s how you can approach resolving the P0014 code:
- Check engine oil: Make sure the oil level is sufficient and the oil is clean and of correct viscosity.
- Inspect the camshaft actuator: Look for wear or electrical issues.
- Test the camshaft position sensor and control solenoid.
- Use a scan tool to monitor OBD II live data for camshaft timing irregularities.
- If necessary, update or reprogram the engine control module or PCM.
If you’re unsure, a certified mechanic can perform a full diagnostic.

Conclusion
The P0014 code shouldn’t be ignored — but it’s also not a death sentence for your engine. Whether you’re driving a Chevy Equinox or a Hyundai Elantra, staying on top of oil maintenance and understanding how VVT works can save you from costly repairs.
If your vehicle uses OBD II, make sure to scan frequently, especially if you notice the check engine light. Addressing a camshaft timing over-advanced issue early will ensure long-term reliability and performance.
Frequently Asked Questions (FAQs)
What does the P0014 code mean?
The P0014 code indicates that the camshaft timing on Bank 1’s exhaust side is more advanced than the engine control module expects. It often relates to issues in the camshaft actuator or variable valve timing system.
Can I drive with a P0014 trouble code?
While your car may still run, driving with a P0014 code is not recommended. It can lead to poor performance, increased emissions, or even internal engine damage if ignored.
How do I fix a P0014 error code?
Start by checking your engine oil level and quality. If the oil is fine, inspect the camshaft actuator, camshaft position sensor, control solenoid, and wiring. Replacing a faulty part or resetting the ECM may be necessary.
What causes camshaft timing to be over-advanced?
Low oil pressure, dirty oil, a faulty VVT solenoid, worn timing components, or ECM calibration issues can all cause camshaft timing to advance too far.
Is P0014 code common in Chevy Equinox?
Yes, the P0014 code is a common issue in Chevy Equinox, particularly models equipped with VVT systems. Regular oil maintenance is crucial to prevent this error.
Can old or low-quality oil cause P0014?
Absolutely. Dirty or incorrect oil can disrupt oil pressure and VVT function, leading to camshaft timing errors like P0014.
