P0096 Code – What Does It Mean & How To Fix It

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.


The OBD II Problem Code P0096 indicates that the intake air temperature sensor 2CPerformanceRange has a problem. An essential component that provides the engine control module with information on the temperature of the incoming air is the Intake Air Temperature Sensor IAT.


The P0096 code is triggered when the powertrain control module (PCM) detects an abnormal voltage signal from the Intake Air Temperature Sensor 2. In order to achieve optimum performance, the PCM relies on data from this sensor to adjust the air-fuel mixture, ignition timing, and other engine parameters.


Several factors can lead to the activation of the P0096 code, including:

  • Faulty Intake Air Temperature Sensor: A defective or damaged IAT sensor can provide incorrect temperature readings to the PCM.
  • Wire Problems: The signal from the IAT sensor might be distorted by corroded or damaged wires and connections.
  • Sensor Position: The IAT sensor can provide erroneous readings if it is placed too close to the engine or in a region where it is exposed to high heat.
  • PCM Malfunction: The IAT sensor may give false readings if the powertrain control module is malfunctioning.


You could encounter the following signs and symptoms when the P0096 code is present:

  • The Check Engine Light Is On: The check engine light on the dashboard of the car is the first obvious sign.
  • Diminished Engine Performance: Due to incorrect air-fuel mixture changes, the engine may show diminished power and performance.
  • Poor Fuel Efficiency: Poor fuel efficiency can be caused by inaccurate sensor readings that result in inefficient fuel burning.


An OBD-II scanner or a certified mechanic must follow a step-by-step procedure to properly diagnose the P0096 error code. Typically, the diagnosis entails:

  • Code reading: Use an OBD-II scanner to get the P0096 code and any associated codes.
  • Visual Inspection: Look for any rust or obvious damage in the wiring and connections of the IAT sensor.
  • Sensor testing: Check the resistance and voltage output of the IAT sensor to see if it complies with the manufacturer’s requirements.
  • Check for PCM Issues: Examine the PCM and its connections for any potential problems.

Common mistakes

Dealing with the P0096 error code might result in errors like these:

  • Ignoring the Code: Ignoring the P0096 code and the check engine light might cause the engine to run less smoothly and perhaps endanger other engine parts.
  • Replacing the Sensor Without Proper Testing: If the fundamental cause is elsewhere, replacing the IAT sensor without first confirming its operation might result in excessive costs.
  • Ignoring Wiring Problems: Failing to search for corroded or broken wiring might lead to incorrect identification of the issue.

How serious is this?

Although the P0096 code is not capable of causing a vehicle to fail immediately, it should not be disregarded. Insufficient maintenance can have a detrimental effect on engine performance and fuel efficiency, as well as cause possible damage to other components of the engine.

What repairs can fix the code?

repair manuals

Possible fixes for the P0096 error code include:

  • Replacing the Intake Air Temperature Sensor: If the present IAT sensor is broken or defective, install a new one.
  • Fixing or replacing the wiring and connectors: Take care of any wiring and connection problems with the IAT sensor.
  • Moving the IAT Sensor: If the sensor’s positioning is resulting in inaccurate results, think about moving it to a better area.
  • PCM Reprogramming or Replacement: If the PCM is malfunctioning, reprogramming or replacing it may be necessary.

Related codes

Other related codes that may accompany or be triggered by P0096 include:

  • P0095 – Intake Air Temperature Sensor 2 Circuit
  • P0097 – Intake Air Temperature Sensor 2 Circuit Low Input
  • P0098 – Intake Air Temperature Sensor 2 Circuit High Input


Finally, the entry P0096 DTC code shows that there may be a problem with the Intake Air Temperature Sensor 2 circuit. It is essential to resolve this issue quickly so that optimum engine performance, fuel efficiency, and vehicle reliability can be maintained. If you encounter the check engine light with a P0096 code, seek the assistance of a qualified technician to diagnose the root cause accurately and perform the necessary repairs. 

In order to ensure the smooth and efficient performance of your vehicle, it is possible to take preventive steps by studying the P0096 codes’ meanings, characteristics, symptoms, and potential fixes. In order to prolong the life of your vehicle and avoid more difficult problems in the future, it is vital that you regularly carry out maintenance and repairs as soon as possible.
