I was at the dyno and my air tempsensor is reading 14 degrees what could be the problem

anyone i need help fast

Bad temp sensor, bad ground, corroded connections...Maybe it was that cold and you didn't know it

 

no it was on the dyno we went through the connection and the wires were all connected, what ground would make it go bad, also i have never heard of a sensor goin bad, anyone else have any ideas

They can and do go bad. Just not very often.

 

would this then most likely be it?

If you have access to a mutli-meter you could do a simple test. The IAT & ECT share the same resistance/temp characteristics. On a cold motor [in the morning time works well] unplug the IAT & ECT sensor connectors. Then measure the resistance of both sensors.....they should be nearly the same.

But as far as IAT [and ECT for that matter] resistances for varying temps, use these values:

Temp: Ohm
32: 5000
68: 3000
104: 1000

If your sensor checks OK, look to your wiring.

 

Thanks alot im gonna be tuning again this friday and hopefully a new sensor will dothe trick if not is there anything else it could be
