The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P251D fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P251D code is an OBDII fault code that relates to the Power Take Off (PTO) Engine Shutdown circuit. The Powertrain Control Module (PCM) is responsible for monitoring this circuit. If the PCM detects that the PTO Engine Shutdown is not within factory specifications, it will set the P251D code.

This fault code can indicate a problem with the PTO Engine Shutdown circuit, which is responsible for shutting down the engine when the PTO is engaged. If this circuit is not functioning correctly, it can lead to engine damage or other issues. It is important to address this fault code promptly to avoid any potential problems.

What is the possible cause of the P251D fault code if the engine light is on?

If the engine light is on and the P251D 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 check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector pins.
