Hey guys, i'm new on the forum and brazilian, so my english isn't perfect .
I have a problem with coolant temp sensor, as u can see in the image below:
(i've tried to upload but doesn't work, so i post the links)
They are working perfectly, but sometimes (more than i've expected) the sensor oscillate and the CLT goes to 230ºf in 0.1s, then back to normal (192ºf).
I change the CLT sensor and the problem persists.
I have an aftermarket ECU in the original wire (plug n play megasquirt MS2), but with original ECU (with ecmlink) I already had the problem.
There are images of my original wiring. Three white wires going into green sheeths. These wires go to pins 75, 76, and 78 (Front O2, Rear O2, and Knock Sensor).
There are also 5 black wires (one of which is pin 92 [Sensor Ground]) that are coming from the wiring harness, through the green sheeths, and then the all of the black wires are soldered back to the sheilding inside the sheeths.
My problem is these wiring? Anyone can help me?
Thank you and sorry for the gramatical errors
