Air temp sensor problems

[95Blue240sx]

I've done search and found nothing on what im dealing with. the problem is i got code 41, air intake temp sensor. so i replaced the sensor and rest the ecu. i start the car and within a minute the check engine light come back on. i check it again and its code 41. so i start the car unplug the sensor and check to see if it is getting voltage, and it is not. so im thinking maybe that it god cut somewhere going to the sensor. im about to go check to see if i get voltage from the line coming out of the ecu. then ill go from there. i do not have an intake or anything. just a drop in filter. but i've had the filter in there for a couple years now and the check engine light came on about 2 weeks ago. help me out. thanks!

weird... i ran my car for like a week with the air temp sensor unplugged and didn't get a CEL. although, i think my CEL bulb may be dead :p

i had the same problem. after replacing it didnt go away
so i checked a few thngs, didnt change or rpelace anything. after driving around for a few hours, the light turned off. go figure.

cars suck.

heres what i did. i checked the voltage on the plug, where the sensor plugs in to. the black is ground the other is hot. so check ground first. get a volt meter and black into the black on the plug and red to positive on the batt. should get a reading like 14v when the car is on. then check voltage from the hot side, blue wire, and ground(any metal on the car/engine) and get like a 5v reading. when i was doing this i did not get a 5v reading on the hot side. so i went to the ECU and checked the voltage coming out of there(i have ECU wiring diagram if anyone needs) it read 5v so i figure the wire is messed up somewhere. so i just soldered in a new wire from the ecu and ran it to the plug then plugged the sensor in, reset ECU and no CEL. :D
