Hi guys, need some help here.

My oil pressure gauge died yesterday afternoon, and after driving for a while, it jumped back to life with dead needles on 5.5 kg/cm3 and the warning light was on.

I didn't notice a change in the car's behaviour at all last night. The car drives like normal, and after a while the gauge is showing the normal pressure numbers (2.5-4 kg/cm3 when idle, 6-7 kg/cm3 when driving normally) but the warning light just stays on constantly.

Disconnected the cable last night hoping it will reset itself, and I just checked the oil this morning, its showing half full.

If its any help, the gauge is a Greddy gauge, and my car is an MY00 with ECUTEK, VF35 & FMIC, Turbo back 3 inch.

Anyone here can help?
