Trouble code help
I've got a 98 Tacoma 4x4 with the 2.7l 4cyl. I recently got a cel and scanned it and came up with P0125. The code comes back as "Insufficient Coolant Temperature for Closed Loop Fuel Control." I was thinking that maybe the engine coolant temp sensor was bad. The Haynes manual says its located on the back of the head, but I can't seem to find it if it is. There is a very small sensor screwed into the top of the water neck where the thermostat goes. I was wondering if anyone can verify the location of the ECT and what the sensor in the water neck is. Any help would be much appreciated.
Thanks,
Terry
