2004 GT3 Oil Pressure Gauge

Electrical and Electronic

Vehicle Information: Model: gt3; Year: 2004; Body Type: Coupe; Total Mileage: 12000;

Periodically, while driving down a levelroad at moderate rpm, the oil pressure gaugedrops to zero, setting off the check enginechime. This lasts for 3-4 seconds and thegauge then returns to the max pressure position.Could this be caused by some kind of outside electrical interference or could the oil pressure pickup be contaminated or obstructed? I can't believe the engine is actually losing needed pressure. Thanks for your help..... Pat
