Hi Dennis,

I just dealt with this myself. I lost the AC belt on my 2.1 recently and shortly thereafter had oil pressure sensor problem. Check the brown wire that goes to the high pressure oil pressure sensor. If your oil pressure buzzer/light only goes off over 2000 rpm, it is specifically this sensor. Mine got damaged when the AC belt decided to self-destruct. A little solder & heatshrink fixed the problem.

Cheers, JD
