i do believe its on the left side of the engine where the upper rad hose connects into the block. It should be attached to a coupler at the end of that hose.

Ok I found it and replace the sensor, it fixed the high idle, hard starting, richness when driving, fuel mileage, overdrive not engaging problem. Figured I would let you know that it is directly underneath the heater core lines that come out of the firewall. Really small hands help alot!
