Guys, I need a favor if you please.......

Could you guys please check your grounds resistance on your IAT and MAP sensors with

1.) Ignition Key off
2.) Ignition Key on (do not start car)

I have voltage in my ground wires for these two sensors and are giving me bad readings.

IAT reads 155 degrees farenheit on a cold start and stay there. It reads 332 degrees farenheit with the sensor unplugged.

Should read same as ambien tempature, and it should read -33 degreess farenheit with sensor unplugged.

Please help.. Very desperate. I am trying to diagnose if my ECM is dead.
