Oil Pressure Sensors

[Kevin.FILLIP@domain.elided]

     Thanks to all who responded to my questions on the oil pressure sensor 
     set up on the Series 4 Spider. For those interested, there are in fact 
     two different oil pressure sensors on the car. The first controls the 
     low oil pressure idiot light on the dash and is located on the lower 
     potion of the drivers side block right next to where the dipstick 
     exits. This sensor is a screw in type with a single plug (looks like a 
     temperature sensor) which connects to the wire running to the warning 
     lamp. It screws into a metal fitting which parralels the block and 
     which attaches to the block via another small metal pipe at a right 
     angle via a 19mm bolt. The second sensor which actually measures the 
     oil pressure, is located on the back of the block on the passengers 
     side and is extremely difficult to get to. This looks like a small 
     "oil can" and screws into the block at a right angle. Interestingly, 
     neither sensor is shown anywhere in the shop manual. So if your oil 
     pressure warning light is acting up, or your oil pressure guage is 
     reading low, check out those sensors.
