Replacing an Engine Temperature Air Sensor on a Diablo

The two air temperature sensors on a Diablo can fail from time to time. This will fire up the left or right check engine light. Fortunately replacing them is easy and not too expensive.

An Air Sensor is shown here on the left. It is a simple device containing a small red bead connected to two wires which I assume changes its electrical conductivity depending on the oxygen content of the air.  A blowup below shows this bead is shown in figure 2.. Its location in the engine is shown in figure 3. Note there is a left and right sensor. 

Thanks to Dave Ayres, Sacramento, CA. for the photographs.
