How do I fix a 2005 Chevy Trailblazer code PO113


Intake Air Temperature Circuit High Input

A code P0113 may mean that one or more of the following has happened:
Internally failed IAT sensor Faulty connection at IAT sensor
Open in IAT ground circuit or signal circuit
Short to voltage in IAT signal circuit or reference circuit IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
Faulty PCM (less likely but not impossible)

I have a lincoln town car 2003 I have this code po113 IAT sensor 1 circuit high input I changed my MAF and it started up but not like it should can someone please help me out


code p 0113 refers to intake air temperature (IAT) sensor --circuit malfunction===causes wiring open circuit / short to positive ---wiring short to ground ---ground wire defective --IAT sensor---ECM
the MAF ( mass air flow) sensor has nothing to do with the fault
the fault is in the wiring or the IAT sensor

Try cleaning intake and throttle body.

Code PO113


Diagnostic Trouble Code (DTC) P0113

Intake Air Temperature Sensor High Voltage



What is the circuit like?


  • In order to regulate the signal voltage going to the engine control module (ECM) the Intake Air Temperature (IAT) Sensor utilizes the thermistor.
  • This circuit receives a 5 volt reference voltage and a ground to the sensor supplied by the ECM.
  • The IAT sensor signal voltage will be high when the air is moderately cold as the resistance will be high.
  • The IAT sensor signal voltage will be low when the air is moderately warm as the resistance will be low.



I hope this helps, mike from fixya, I am writing another comment in another comment to continue some. Thanks Mike

Try unplugging and plugging the map sensor, this device should have manifold pressure hooked up to it, via hose, so check for cracks or leaks. Then clear codes and test again.

Your IAT sensor may be faulty. It is a sensor on the intake manifold.
