P0113 Code 6.0 Powerstroke: Causes, Symptoms and How To Fix P0113 Code?

If you drive a 6.0L Powerstroke Diesel, chances are you’ve encountered the dreaded trouble code P0113. This error P0113 code 6.0 Powerstroke indicates that the Intake Air Temperature (IAT) sensor is reporting a temperature that is too high. This problem can be a real headache for many drivers. But don’t worry – if you stay with us, we’ll help you to understand the causes and symptoms and diagnose and repair this issue quickly and easily. In this article, we’ll explain what the P0113 code means, the common causes of this code, and the recommended steps for repairing it. So let’s get started.

Causes and How To Fix P0113 Code 6.0 Powerstroke

What does the p0113 code mean on 6.0 Powerstroke?

The p0113 is an error code generated by the power-train control module (PCM) in the Ford 6.0 Powerstroke engine when it detects abnormally high air temperatures within the intake manifold or a failing intake temperature sensor.

The intake temperature sensor is a resistor. The powertrain control module sends a constant voltage of 5 volts to the IAT sensor and measures how much of the voltage makes it back.

Since resistance is affected by temperature, the IAT sensor varies its resistance depending on the temperature of the air passing through the intake manifold.

When the PCM receives a voltage near or equal to 5 volts, meaning no resistance from the IAT, it considers this abnormal, sends out the p0113 error code, and lights up the check engine light.

Where is the intake air temperature sensor Located on 6.0 Powerstroke Vehicles?

The Ford 6.0 Powerstroke engine has two IAT sensors. IAT sensor 1 is used to measure the ambient temperature. IAT sensor 2 is built into the mass airflow sensor and located inside the intake manifold, just behind the fuel line that feeds the filter assembly.

The PCM uses the signal from the IAT 2 to determine the appropriate air-to-fuel mixture for the engine. In this article, we will be looking at the IAT 2 (the one inside the intake manifold).

what can cause a p0113 code On 6.0 Powerstroke?

There are minor causes and major causes of the p0113 error code.

The minor causes Behind The P0113 Code On 6.0 Powerstroke Are:

Disconnected wire socket.

If the wire socket is not connected back to the IAT sensor, for example, if it had been disconnected while servicing the manifold or nearby components, the PCM will give a p0113 error.

A broken wire connection.

Due to the position of the IAT connector socket in the 6.0 Powertrain, the wires can experience increased pressure, which can lead to the outer wire breaking internally. 

Loose wire connections.

Due to engine vibrations and other disturbances, the wires inside the connector socket can loosen over time and break contact with the IAT sensor. 

A dirty air filter.

When the air filter is dirty and clogged, the engine will work harder to draw more air leading to an increase in temperature within the intake manifold. 

The major causes that can lead to a p0113 error code include the following:

A defective mass air inflow sensor

When this sensor malfunctions, the engine will compensate by drawing in more air and increasing pressure and temperature within the intake manifold. 

Faulty IAT sensor

When the IAT sensor malfunctions or cannot pass the voltage, the PCM will give out a p0113 error code. 

A faulty PCM

A faulty PCM is unlikely to cause the error, but it can still happen. However, if the PCM is at fault, it will give out many other error codes, not the p0113 error code alone. 

What are the Possible symptoms of the p0113 code On the 6.0 Powerstroke?

  • The check engine light will come on.
  • Loss of power or engine increased engine strain. Indicates a dirty and clogged air filter or a malfunctioning mass airflow sensor. 
  • A hard start in cold weather. When the PCM does not receive accurate information about the ambient air temperature, it will not adjust the air-fuel mixture accordingly to start the engine in cold weather.
  • Rise in emissions. Due to the wrong fuel-to-air mixture.
  • Poor acceleration. Again, the poor air-to-fuel combination means the vehicle does not operate optimally during demanding situations, such as when accelerating.
  • Poor fuel economy. The Ford 6.0 Powerstroke engine is big and thirsty. When the PCM receives inaccurate air temperature data, it compensates by adding more fuel to the mixture, leading to an abnormal increase in fuel consumption. 

how to fix p0113 code: How does a mechanic diagnose and Repair the p0113 code on 6.0 Powerstroke?

To correctly diagnose the P0113 error code, the mechanic uses two tools:

  1. a scanning tool
  2. a multimeter

Step 1.

The mechanic will visually inspect the air filter, and if it looks dirty, it will be replaced. The mechanic will then connect the scanning tool to the vehicle’s onboard diagnostic port and observe if the error code persists. 

Step 2

If the error is still present, the mechanic visually inspects the IAT wire socket connections for any loose, broken, or corroded wires. If any, replace the individual wires or the entire socket and check the code again with a scanning tool.

Step 3

If the error code persists, the mechanic will carefully remove the IAT sensor from the intake manifold and measure its resistance using a multimeter. When IAT is exposed to heat, the resistance reading should reduce.

If this does not happen or the reading remains the same, that IAT sensor is faulty and the cause of the p0113 error code. 

The IAT sensor should be replaced with a new one to fix the problem. 

Common mistakes when diagnosing the p0113 code On 6.0 Powerstroke?

The most common mistake made while diagnosing the p0113 code, especially by DIYers, is rushing to remove and test the IAT sensor before checking the wire connections and the state of the air filter. 

Before attempting to remove the IAT sensor, ensure you have replaced the air filter and that there are no broken, faulty, or corroded wires in the connector socket.  

What repairs can fix the p0113 code On 6.0 Powerstroke?

  • Replacing the air filter can fix the p0113 code caused by a dirty, clogged air filter.
  • Checking and replacing any broken, damaged, or loose wires will fix the p0113 code caused by a wiring problem.
  • Replacing a faulty IAT sensor will fix the p0113 error code caused by sensor malfunction. 

How serious is the p0113 code? Can you drive with dTC p0113 on your 6.0 Powerstroke?

The p0113 code is a serious error but not an emergency. It would be best if you got your vehicle checked as soon as possible when the check engine light comes on. 

Driving for extended periods with the p0113 error code can lead to a damaged catalytic converter and an inefficient engine to poor air-to-fuel combination leading to other engine problems over time.
