Engine Alarm

[redlaw]

I have a Formula 2002 330ss with dual 6.2's. Recently I have had a double beep every 60 seconds alarm go off. Computer analyzed 555 EMC program shows zero water through the port engine. False reading based upon engine temps 5x5 and direct feel hands on temp for both motors . Alarm goes off at idle and when running the engines. I think it is a faulty sea water electronic sensor, but don't know where the sensor is. Help!

In the power steering oil cooler, at the back of the engine.. Known failure point. Make sure the cooler and the sensor are clean and have a good ground when you put the new one in.

Use a voltmeter and measure the voltage at the water pressure sensor pointed out by Chris, it should be 5V
