P251E Severity
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.
The PTO allows Auxiliary equipment such as a dump bed or plow to be hydraulically operated using the vehicle's transmission. The PTO will shut off the engine if the load on the PTO becomes too great. This is done to prevent damage to the engine and/or transmission. If the PTO Engine Shutdown switch sends an implausible signal, code P251E will be stored. PTO operated features will not work.
