| Fault code 559 So we just added a t680 to the fleet, it has an ISX, and my driver said it loses power at highway speeds. I plugged in INSITE and I got a fault code 559 injector metering rail 1 pressure data valid but below normal operating range moderately severe level. How can I go about troubleshooting the source. Does INSITE have a way of showing me the current real time pressures going thru the fuel system? I changed fuel filters already and I still get the code. I’m going to check the fuel pump tomorrow, but I’ve heard the is very hard to pinpoint. Any one else have this problem or is there a thread about fault code 559 already? | |||
