What causes code P0113?

What causes code P0113?

Error code P0113 indicates that the computer has received a high voltage signal from the intake air temperature sensor. This code will occur when the powertrain control module (PCM) receives a voltage of 5 volts or more from the IAT. This indicates a problem between the IAT and the PCM.

Is it bad to drive with a bad IAT sensor?

A malfunctioning IAT sensor may cause your vehicle to take longer to start on cold mornings. The faulty IAT sensor tells the car’s computer that the air in the intake is a different temperature than it actually is and may cause the vehicle to not deliver the proper fuel mixture to the engine.

How do you know if your IAT sensor is bad?


  1. Fault code is stored, engine indicator lamp may come on.
  2. Problems starting.
  3. Reduced engine power.
  4. Increased fuel consumption.

What can I use to clean IAT sensor?

They recommended a spray solvent made by CRC called “QD Contact Cleaner.” You can get it at Lowe’s and Home Depot, in the electrical area. I got some and cleaned the MAP and temp sensor and bingo: instant smooth idle.

What can I use to clean my intake air temperature sensor?

Remove & Clean The IAT Sensor

  1. Locate the sensor, disconnect the cable.
  2. Use your Torx T30 to remove the screw.
  3. Carefully pull the sensor out and gently drop it into a ziploc bag.
  4. Fill it up with isopropyl alcohol just enough to fully submerse the sensor.

What is the difference between MAF sensor and IAT sensor?

MAF is an acronym for “mass air flow.” Unlike IAT sensors, MAF sensors measure air volume with temperature at once. An MAF actually measures real air volume so that the computer doesn’t need to guess what it might be.

What should MAF sensor read at idle?

With the engine at idle, the MAF’s PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 rpm, depending on engine size. Most manufacturers provide specifications for air flow at idle; some will provide specifications at several engine speeds.

Is MAF same as IAT?

IAT (intake air temperature) is NOT a MAF (mass air flow) equivalent. Your car uses a MAP (manifold absolute pressure) sensor in place of a MAF. Cleaning the throttle body is a great suggestion.

Do I need a IAT sensor?

Registered. An IAT or MAT sensor is only necessary if you want to be able to use Charge temp estimate for fueling (used for all fueling modes in latest firmware), or make corrections for abnormal IAT (a great idea). It can really help make fueling more consistent over a wider range of operating conditions.

What is a good IAT reading?

Typically, the temperature readings should be 10 degrees more or less than the vehicle’s ambient temperature, depending on the outside temperature and the engine’s temperature. If the readings are not realistic, there could be a problem with your IAT sensor or the wirings to it.
