I need to know which sensor plug goes to which sensor on this diagram, looking at number 11 and 12. What is each of these sensors and what do they do and if possible i need to know what plugs to each. I cant find a plug for both of these only 1 listed as Engine Coolant Temperature which I think is #12 but then I have nothing going to number 11?

 

i think that it's the number 11 .

What are number 10 and 12 for ?

 

what engine is it?

 

the top one is a coolant temp sensor for obd0 ls engines and the bottom is the same but for obd1 and later cars

 

its a 1997 B18b1 and my engine has one sensor on the Thermostat housing, and 2 on the side of the head. The picture above is of a 2000 B20 but it looks identical to my head.

 

number 10 : THERMO UNIT
Part number : 37750-PH2-014

Number 12 : SENSOR ASSY
Part number : 37870-PJ7-003
