P0014 means the exhaust cam is stuck open - oil sludge is the prime suspect. A VVT solenoid stuck in the open/advanced position keeps feeding oil pressure to the actuator. Check oil condition immediately and clean or replace the exhaust cam solenoid before ruling out the phaser. See top-rated scanners on Amazon ↗

These are statistical causes across ALL vehicles - your exact car may rank differently
For example, on a Honda 4-cyl the downstream O2 sensor causes P0014 64% of the time, but on a GM 5.3L V8 the catalytic converter is the cause 71% of the time. Get a probability ranking built specifically for your year, make, model, and mileage.

🎯 Top Causes & Probability
50%
#1 - Most Likely
VVT Solenoid Stuck Open
The exhaust cam VVT solenoid is stuck in the open position, continuously feeding oil pressure to the actuator and keeping the cam advanced beyond the commanded position. Sludge from degraded oil is the most common cause of solenoid sticking. Replace the solenoid and perform an oil change together.

#2 - Check First
Sludged Oil Passages
Oil sludge buildup in the passages leading to the exhaust cam phaser prevents proper oil drainage from the actuator, keeping it in an advanced position. Extended oil change intervals (beyond 7,500 miles with conventional oil) accelerate sludge formation. A full oil flush may be needed.

#3 - Less Common
Timing Chain Wear
A stretched timing chain allows camshaft position to vary from commanded. The ECM may see the exhaust cam as over-advanced when the chain has enough slack to alter cam phase. A cold-start rattle points to this cause. Timing chain replacement is required.

Exhaust Cam Actuator Failure
The exhaust cam phaser/actuator has worn internally and is stuck advanced regardless of solenoid command. Confirmed after oil change and solenoid replacement yield no improvement. This is the most expensive repair in this code's diagnostic tree.

🔧 Step-by-Step Diagnosis
- Perform Oil Change First - Change the oil and filter using the OEM-recommended viscosity. Use full synthetic if possible. Clear the code and drive 50 miles. Many P0014 codes are resolved by fresh oil alone if the solenoid is not mechanically damaged.
- Replace Exhaust Cam VVT Solenoid - Locate the exhaust cam oil control solenoid on Bank 1. Remove and inspect for debris on the screen filter. Replace with a new OEM or equivalent solenoid. Clean the mounting bore before installation.

Tips for Choosing a Shop
- Ask if they charge a diagnostic fee and whether it applies toward the repair
- Request a written estimate before approving any work
- Ask specifically about the part brand - OEM vs. aftermarket matters for this code
- Check Google reviews for recent mentions of the specific repair you need
