Well i was in the process of looking into replacing my coolant temp sensor on my 1.8tQ 5sp and i noticed this





Where is the sensor on the left supposed to connect to? I dont see any connectors that are unhooked

thanks in advance, Kyle

 

nobody knows?

 

that looks like the Engine Coolant Temp Sensor..... but then wth is the blue cord?

 

The blue cord connects to the coolant sensor. i took it out and checked the p/n and its the coolant sensor

the green connector on the other hand i have no idea

 

it looks like another one... what year is your car?

 

It could be for test equipment hook-up?

99.5 ECTS.. only has 1 (took picture just now... i just put my new ECTS in today)

 

i just bought a replacement coolant flange thing (the plastic piece those sensors hook into) and for my car it only has one sensor, but the flange has holes for 2 sensors, so it came with a plastic plug for the second hole. maybe someone just threw an old sensor in there instead of a plastic plug? you would get a CEL if it should be hooked up.

 

That sounds about right

Thanks alot!!!!!!
