Need Help with IAT sensor not reading
 

Hello

so here is how it started in IN NJ with this crazy weather so on Monday my NA starting running to LEAN according to my gauge so i was like may be is because is really cold so i did not to much mind to it then on Wednesday it was warmer around 60f and started running to Rich then i connected my laptop and the air temperature is not reading so i check cables and everything is fine so next ck the Sensor with a voltmeter and a hair drier and the voltage change

now idk what ells can be wrong why is not reading the temperature

im running on MSMPNP 1

Please Help

Exactly what voltage did you measure?

Are you using the project for "no MAF"?

the reference wire positive showing me 4.2v and i also test the ground and show me 12v

and yes i remove the AFM

Are you saying you had 12 volts on the IAT sensor? I'm confused.

No I found the problem the connection on the main harness what split now I repair it and everything work well until today the temperature sensor started acting up again so I check the cable repair every look fine but now the inside if the sensor looks lose??
