P1193 is an intake air temp code, there is a sensor somewhere within the filter box or the intake tube (large rubber tube running to the intake) with a plug that normally has two wires. You can remove the sensor and clean it (this will sometimes fix the problem) or replace it. You should reset the codes to verify the fix.
SOURCE: Code
The code is for the inlet air temp sensor voltage high. Check and make sure the sensor is plugged in, It will be on the intake manifold or the hose to the intake manifold. If it is plugged in you need to check that all the wires are in good condition. If they all look good there are alot of possiblities for the cuase of this code. Most likely cuase is the inlet air temp sensor. But it could still be in the wiring or in the pcm (engine computer)
