P2581 OBD-II: Turbocharger Speed Sensor Circuit High

P2581 Severity

Moderate

Will P2581 go away on its own?

Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.

For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.

Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.

Schedule Diagnosis

What causes OBD-II fault code P2581?

The Turbocharger is programmed to spin at a certain speed based on the engine's RPM. If the Turbocharger deviates too much from the anticipated speed of rotation, code P2581 will be set.
