What would cause this to fail? Air Intake Circuit High Input Has anyone had this problem before? Could it be the MAF? or wiring problem?

 

It indicates a problem with the IAT sensor. Could be the sensor, could be the wiring. You're lucky, that's the easiest sensor to change and they're cheap. You'll find it somewhere between the air filter and the throttle body.

 

ok...thanks

 

GM Fixer,

For an even more explicit idea as to where this sensor is located, it is key #13 in this '97 Malibu Intake diagram


Cheers mate!

 

YUP...the P0113 code is still coming up. Harness checks out ok. looks like I am going to have to replace the sensor. IAT.

 

Double check harness and there was a broken wire, sensor checked out fine
