Hi All,

Anyone have experience with this code on a 2018 3046R?

What google told me was "Low pressure fuel pressure high". If that was the right chart for my tractor?

If this is correct what would cause it? The tractor has 56 hours on it. :unknown:

Scenario was. Cool engine. (Had been running about 5 minutes) Stop light and chime came on along with error code "ECU A 157.16" in instrument display. Shut down tractor, waited 5 seconds, restarted tractor, all normal. 30 seconds later light, chime and code were back. Shut down, waited 5 seconds, code, chime and light gone, no further issues. On th elast restart, I advanced power to rated PTO RPM. Prior to that it had been running about 1500-1500 RPM.

Thanks!

Jeff

According to the TractorPlus phone app, 157.16 is listed as Rail pressure limiter is open. Searching further on Google, it indicates that there is not enough fuel pressure. Since I’m not a diesel mechanic, I don’t know what that means exactly. It sounds like either a pressure relief valve is open or a sensor is indicating a loss of pressure or both. I would call the service department and see if they give you a solution other than bring it in unless it’s still under warranty.

I have the same error code.

My tractor is a 3032. Spent the day taking out injectors and fuel rail and rehooking them up to test them and they seem to be firing fine. There is a fuel rail relief valve that seems to be not working. The fuel rail on the back side says BOSCH on it but I can't find what the fuel pressure is supposed to be?
