Fans have been checked, Hoses and thermostat have been replaced, relay and fuses checked. Fans are not coming on. I see a sensor on the right sided where the transmission coolant hoses are located. I found the oil pressure/ temp sensor near the oil filter. I can see a sensor on the back side of the engine that would have to be pulled from underneath. Check Engine light came on a month or so ago. The weather may have been cold enough to keep the engine cool without running the fans. Any additional ideas?

Most coolant temp sensors located on thermostat housing- usually at end of upper radiator hose.

Thanks for the info. I replaced the themostat and did not see the sensor. There is a block on top of the housing where the plug wires run through. I se no wires that woulld kead to a sensor in or under the block. Could it be under the intake maifold where the injectors go into the heads?

Oh gosh not sure. I'd call your local Autozone and they have pretty good records on component location. Maybe even stop by a store cuz they maybe able to print you a little diagram.
