My '07 310SS with twin 6.2 MPI Horizon engines and BIII drives has been sounding an alarm on the port side and reading "water pressure sensor not functioning properly". Replaced the sensor, when in h2o mode the gauges read within 5 psi of each other, no temp issues and then when the alarm goes off, the port side reads ---- in h2o mode. Does this sound like an electrical issue?
