The P251C code is an OBDII fault code that relates to the Power Take Off (PTO) Enable Switch circuit.

The Powertrain Control Module (PCM) is responsible for monitoring this circuit. If the PTO Enable Switch is out of factory specifications, the PCM will set the P251C code. This fault code indicates that there is a problem with the PTO Enable Switch circuit.

Specifically, the circuit is reading as high, which means that it is not within the expected range of values. This could be caused by a variety of issues, such as a faulty switch or a wiring problem.

If you receive the P251C code, it is important to have your vehicle inspected by a qualified mechanic.

They will be able to diagnose the underlying issue and make any necessary repairs to ensure that your vehicle is running smoothly and safely.

What is the possible cause of the P251C fault code if the engine light is on?

If the engine light is on and the P251C fault code is detected, it could be due to a faulty Power Take Off (PTO) Enable Switch, an open or shorted PTO Enable Switch harness, or a poor electrical connection in the PTO Enable Switch circuit. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P251C fault code if the Power Take Off (PTO) Enable Switch harness is open or shorted?
