I have a 91 LS400 but the manual I have is for a 94. when I read out the fault code, it blinks 4 times, then 1. There is no code 41 in the 94 manual. Can anyone help?

Like am idiot, I bought a new battery from Costco and attempted to switch it out myself. I have done this several times on different vehicles, but this time I really blew it! The new battery terminals were opposite of the old battery and I attempted to hook it up backwards, blew the main engine fuse (100 amp) and the dome light fuse also. I replace the fuses but still have the following issues: The oil pressure and water temperature indicators are malfunctioning. They come on with the ignition switch on, go off when I start the car, then come on again after about 30 seconds. I have checked all of the other fuses and they are fine. Are there in-line fuses for those 2 sensors?
