As with others on this forum, I traced this to a loose oil sensor connector. It's pretty tough to access but I managed to retension the spade connector without removing the airbox. Access is just in front of the left cylinder, below the gas tank on the crankcase itself. There's a single wire going the sensor. I used a long flat screwdriver needlenose pliers to do it.
 
I am currently struggling to remedy the red triangle on my dash for a defect in the oil pressure. I have gained access to the oil pressure sensor, which is deep inside the bike. By taking out the LH exhaust header/downpipe section you can see the sensor and just reach and work on the electrical lead spade connector. As noted above, the sensor is positioned just in front of the LH cylinder, screwed into the top of the crankcase. I tightened the spade connector, no joy; I tested the sensor by disconnecting the electric feed and turning the dashboard/ignition on, then checking for the red triangle; same again with the lead earthed, no joy; then reassembled the exhaust header/downpipe and repeated these tests this time with the engine started and running, no joy. And in every case, I entered the menu on the dashboard and cancelled the warning 07. I have since purchased a new sensor and repeated all these tests with the new sensor connected but not fitted (not keen to fit it if the original is serviceable since access involves removing the fuel tank and air box). Still no joy. Next job is to test the electricity lead from spade connection at the sensor up to Pin 3 on the multi-plug at the back of the dashboard. After that, I have run out of ideas. Any suggestions, please?
 
I went through several oil pressure switches on my Breva 1100 some time ago. I was using a generic oil pressure switch, but was having to replace them repeatedly. It was only when I installed the genuine article the problem was fixed.

I have no idea why the generic ones were failing.
