First replace the oil pressure sender. Its basically an on or off deal. They can get tired and oil ca pass the internal seal causing it need higher pressure to give a signal.

Not sure whether or not you have the OHV engine or the SOHC. I think it is in a similar position on the both but not sure about the OHV
On the SOHC if you look thro the drivers side wheel arch behind the flap just forward and below the exhaust manifold you will see a white plastic cap with one wire attached, thats the baby

Just found this photo
