between 3 and 4 intake runner?
The one at the end front of cyl head is for temp gauge and cooling fans.
The blue sensor have two wires going to ECU. One is a signal wire, the other is ground.
ECU is grounding the coolant sensor at pin 67 on ECU.
This is something to keep in mind, since ground is not at engine block but inside ECU.
The very same black wire from coolant sensor is crimped together with 7 other wires in a junction called J68 before they enter pin 67 on ECU.
The coolant sensor should have approx this readings with measuring over the two pins coming out of sensor.
-14F = 7-11.4 KOhm
68F = 2.1-2.9 KOhm
140F = 0.565-0.670 KOhm
194F = 0.24-0.26 KOhm
230F = 0.14-0.16 KOhm
Hope this help
MAP,EVAP pressure sensor,Air intake,TPS,CKP and both O2 sensors uses the same ground.
