Ive tried replacing it and reseting the ecu and code will not go away. Any suggestions???????????? Also would this code affect idle.

did you make sure you replace the correct sensor. That happen too me so I just replace both

coolant temp sensor is only 8 bucks at autozone replace it... if your gauge is not reading or just jumping around in high rpms just replace it

I bought a new one from nissan 30 dollars. When i check the codes ecu flashes 1 slow 3 fast...coolant temp sensor circuit. The coolant temp gauge seems to read normal.

could be supplied voltage or high resistance in harness, bad ecu, short to ground somewhere. Need more info.

Yea, which one did you do ... one wire or the 2 wire ... the ECU uses the 2 wire , so thats the one that you need to replace ....If thats not it , you need to make sure there isnt a bad wire in the harness ...

I replaced the coolant temp sensor...two wire sensor that sends the signal to the ecu not the one for the gauge. I guess i will have to check my harness or i might have a bad ecu
