P255C OBD-II: PTO Speed Selector Sensor/Switch 2 Circuit Low

P255C Severity

Moderate

Will P255C 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.

What causes OBD-II fault code P255C?

The PTO allows Auxiliary equipment such as a dump bed or plow to be hydraulically operated using the vehicle's transmission. The PTO Speed Selector allows the PTO to be operated at different speeds. If the Speed Selector switch sends back an implausible signal, code P255C will be set and the PTO will be disabled.
