OBD-II Hybrid P3413 Error Code: How to Fix It

Q: Can I drive my car with a P3413 code?

In most cases, yes — P3413 is rated as a medium-severity code and your vehicle will usually remain driveable. However, if you notice rough idling, a significant drop in fuel economy, or your oil pressure warning light comes on, stop driving and have the vehicle inspected immediately. Continuing to drive with low oil pressure can cause serious engine damage.

Q: What causes the P3413 code to appear?

The most common causes are low or dirty engine oil, a faulty Cylinder 5 deactivation actuator solenoid, damaged or corroded wiring to that solenoid, low engine oil pressure, or a clogged oil passage that feeds the actuator. In rarer cases, a failed lifter inside Cylinder 5's valve train can also trigger this code.

Q: How much does it cost to fix error code P3413?

If an oil change resolves it, you're looking at $50–$100. A replacement cylinder deactivation solenoid typically costs $20–$80 for the part, plus 1–2 hours of labor at a shop ($100–$200 labor depending on your area), bringing the total to roughly $150–$300. If the issue stems from an oil pump or internal lifter failure, costs can rise to $500–$1,500 or more.

Q: Will a tune-up or oil change fix P3413?

Sometimes, yes. If the root cause is degraded oil that has lost viscosity or a buildup of sludge blocking the actuator's oil passage, a fresh oil and filter change with the correct manufacturer-specified viscosity oil can resolve P3413 entirely. It should always be your first step before replacing parts.

Q: Is P3413 the same as a cylinder misfire code?

No — P3413 specifically relates to the deactivation actuator solenoid circuit for Cylinder 5, not a combustion misfire. However, if the cylinder deactivation system malfunctions and a cylinder fails to reactivate properly, it can cause symptoms similar to a misfire. Actual misfire codes (P0305 for Cylinder 5) would appear separately if a true misfire is occurring.

Abstract

Error code P3413 indicates a fault in the Cylinder 5 deactivation actuator, a component used in engines with cylinder deactivation (also called Active Fuel Management or Variable Cylinder Management) to temporarily shut off select cylinders at low load for better fuel economy. When this actuator fails or malfunctions, the engine control module (ECM) detects an abnormal signal or no response from the solenoid that controls oil pressure to deactivate Cylinder 5. While the vehicle may still drive, you could experience rough idle, reduced fuel economy, a check engine light, or a slight misfire-like sensation.
