  • I have a 2011 Chevy Cruze I'm working on it has a p0097 I have checked all the normal problems with this concern I have replaced the wiring harness and the computer and could still keep coming back when checking with the scan tool it shows this circuit is shorted unplug the air temp sensor it Still Remains the Same when it should show a negative 40 degrees, do not know what to do if feels like I'm running out of options

  • You said you have replaced the harness and computer, have you replaced the sensor it self? ( the IAT is integrated with the MAP )
