P0113 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0113 would indicate that the computer has received a high voltage signal from the intake air temperature sensor. This code would start occurring when the powertrain control module would start receiving a voltage of 5 volts or more from the IAT. This would indicate an issue between the IAT and the powertrain control module.

A consistent reference voltage of around 5 volts is sent by the powertrain control module or the computer to the IAT. Because it is a thermistor, the IAT would resist that charge based on its temperature and due to that the voltage would be returned to the powertrain control module. This information is used by the PCM to adjust such things as the air/fuel mixture and the EGR valve.

What causes this problem with the Intake Air Temperature Circuit High Input?

• The IAT might be corroded or defective
• Backfiring can occur in the intake manifold
• The tip of the sensor might be contaminated due to oil
• The wiring connector can be corroded or detached
• The IAT circuit might get shorted
• The powertrain control module can start failing

1. Intake Manifold - Are there some faults in your Intake Manifold? Don’t waste time and get them replaced or else P0113 code can turn up.
2. Engine Wiring - OBD Code P0113 can appear because of faulty Wiring.
3. Powertrain Control Module - Everything is fine with turbocharger/supercharger and still P0113 code triggering? Then you must get your Powertrain Control Module checked.
4. Engine Parts - There can be some issues with your car engine due to which you may see P0113 code appearing over and over again. Visit us to buy best quality engine online.
5. Engine Control Module - A lot of issues can arise do to defective Engine Control Module. Did you just see P0113 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
6. Intake Air Temperature Sensor - Faulty Intake Air Temperature Sensor can be the reason why P0113 code is flashing. Visit us to purchase top notch Intake Air Temperature Sensor online.
7. Air Fuel Ratio - Air Fuel Ratio needs full care. Issues with the Air Fuel Ratio can be a reason behind the flashing up of P0113 code.
8. Ignition System - OBD Code P0113 can appear because of faulty Ignition System.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0113 code by mentioning some major symptoms below:

Common Symptoms

• The engine control module would start turning on the check engine light and go into a failsafe mode
• The car engine may not start as usual
• There can be an issue of running extra lean
• Engine may have pre-ignition problems from lean burn conditions

• The IAT connector short should be repaired or replaced
• Repairing or replacing the wiring short as necessary
• IAT should be replaced with a new sensor

• The first thing which you should do is to scan the engine control module, document the codes received, and the freeze frame data should be viewed to see the conditions present when the code was set
• All the fault codes should be repaired and the retest the vehicle to see if the code comes back
• The next thing which you should do is to perform a visual inspection to check for shorting harness or connector to sensor
• The sensor’s live data should be observed very carefully on the scanner while disconnecting the IAT sensor connector to see if the sensor reading goes to -40°F indicating the sensor is shorted
• If you have disconnected the sensor and input is still 240°F then the short is in the connector or harness
• If you find out that there are no problems, then the mechanic should perform the manufacturer's specific pinpoint tests for the code and repair as needed.

Common Mistakes When Diagnosing The P0113 Code

• A visual inspection of connections and wiring should be performed
• A big mistake can be not following the manufacturer pinpoint test procedure step-by-step and skipping steps
• Keep this in mind that IAT sensor should be replaced only when tests indicate a problem
• Not connecting a new or known good sensor to the harness and viewing the ECM data to see if the temperature output from the sensor is as expected
