The P0113 code is an indication that the IAT sensor is not providing the correct voltage signal to the vehicle's computer. The IAT sensor is responsible for monitoring the air temperature inside the engine's intake manifold. If the IAT sensor is not providing the correct voltage signal, it can cause the engine to run too lean or too rich. Lean and rich conditions can cause the engine to misfire, which can cause the P0113 code to be stored.

Users typically search for a solution by asking about:

  • code p0113

1. Replace the IAT sensor

  1. Remove the airbox cover.
  2. Remove the air cleaner box.
  3. Remove the air intake tube.
  4. Remove the IAT sensor.
  5. Clean the area around the sensor.
  6. Install the new sensor.
  7. Reinstall the airbox cover, air cleaner box, air intake tube and airbox cover.

2. Check the IAT sensor wiring for damage

  1. Remove the IAT sensor.
  2. Inspect the wiring for any damage. If there is damage, replace the wiring.

3. Check for intake air leaks

The first step in checking for intake air leaks is to identify the area where the air is escaping. This can be done by checking for leaks around the air intake ducts, around the fuel injectors, and around the engine. Once the area is identified, the next step is to try to find the source of the leak. This can be done by checking for air bubbles or water coming out of the punctured area, checking for carbon buildup around the area, and checking for odors or smoke coming from the area. If the source of the leak is found, the next step is to fix it. This can be done by replacing the damaged parts, adding sealant, or tightening the bolts.

4. Clean the Mass Air Flow (MAF) sensor

  1. Remove the air intake ducts in the engine bay.
  2. Remove the MAF sensor.
  3. Clean the sensor with a soft cloth and a vacuum cleaner.
  4. Reattach the MAF sensor.

Some users might also have success with the following opitons:

  1. Replace the MAF sensor
  2. Check for vacuum leaks
  3. Repair any vacuum leaks
  4. Check the engine coolant temperature sensor
  5. Replace the engine coolant temperature sensor
  6. Check the throttle body for contamination
  7. Clean the throttle body
  8. Inspect the air filter and replace if necessary
