Fuel Mgmt Sys(No P or S)

My fuel mgmt gauge will not display either the P or the S for port and starboard engines. I'm still getting a reading for mpg and total consumption, but when I press the "set" button, nothing happens. I just noticed this the other day. Was working at the beginning of the season. Any ideas? The probability of both sensors being bad at the same time is very little, and if the sensors were bad, would I still be getting fuel consumption readings?

clean sensor connections as its not detecting them.

They should be at the water seperators and at the back of the gauge, right?

they could be installed before or after the seperators...look for the 3 wire/triangular connections.

Thanks. I'll look tomorrow.

Well I worked on the connections and to make a long story short it wasn't a cheap fix. It turned out to be the starboard sensor $289.00. It was an easy fix, but not cheap.

are you sure it wasnt just clogged ??
