thanks pdgizwiz,
had time tonight and checked into coolant temp sensor. I found 3 sensors on water outlet. removed top one and tested it hot and cold, passed resistance as per FSM... middle one just goes to temp guage. The lower one escapes me, couldnt find wrench to fit (bigger than 19mm)....and i could not find the sensor mentioned in FSM. so I started prev and disconnected upper one. It triggered code. Havent had any codes (so I was relieved to see one). I reset CU to see if it comes up again.. at least I know the upper Sensor works...
lower one does nothing that i can tell...so far. any way to test the lower one you know of? its a water temp sensor for sure just not sure what it sends temp to...i may remove it to get toyota numbers off it and look on rockauto or Toyotaparts.com.
I'll let car heat up thoroughly tomorrow and disconnect it to see if any effect on prev.
again thanks for chiming in.
Did you have a HIGH IDLE problem...?
