just wanted to have a second pair of eyes on my voltage and ohm readings across my coolent temp sensor for the ecm on my v8 305 tpi 1986


all readings were made when engine was cold.

ohm reading 4300 which from the chart is somewhere in the 60 degrees range i believe

voltage across the wiring harness disconnected from the sensor is 5v with ignition key turned

plugged in i read 2.65v across the sensor

does this sound like a propper working coolent temp sensor?

i'm just trying to rule it out as a problem with my high idle

its brand new and about a yr old. car has barely been driven 10miles since i put it in.


i dont have readings when the car is hot.

can anyone just give their two cents on my findings. it seems to be up to specs for a cold sensor.

 

Your resistance looks about right.

 

yea i thought so i was lookign at the same chart, anybody have an idea if the voltage readings with the sensor connect is correct?
