  • DF 40 Oil Pressure Light

    DF 40, 2002. Oil light blinking, 2 continual intermittant beeps and rev limited activates at 3000rpms. I have change the oil, filter, oil pressure switch and performed the oil change reset ritual, all to no avail. Any suggestion to correct the problem would be appreciated.

    For the limp mode to activate there has to be serious problems (overheat, over rev, low oil, etc). I recommend taking to your local dealer to have the computer diagnosed.

          hey jonjon , i did the oil change reset thing and my problem solved . you can also verify your pressure with a mechanical guage which will elliminate oil pump and major issues . hope this helps .

              Never was able to solve the problem. I'm now waiting for a dockside mechanic.

                Finally resolved the issue. The wiring harness was not properly secured. One wire had worked loose after 6 years of use. Reconnected the wire and all is well.
