PTO Speed Selector Sensor/Switch 1 Circuit High

The power take-off (PTO) speed selector sensor is sending a signal that is too high, preventing the engine from properly controlling PTO operation on equipment like generators or compressors. This sensor tells the engine which speed the PTO should run at, and a faulty signal can cause the PTO to malfunction or not engage. The driver may notice the PTO equipment doesn't work or behaves unpredictably.
