If you are experiencing unusual response of the throttle, lack of power forms the car engine, impact on the fuel economy and frequent illumination of the Check Engine Light, it might be an indication of the OBD Code P0096 error.

OBD-II Code Decreased engine performance is defined as an Intake Air Temperature Sensor 2 Circuit Range/Performance.

This diagnostic trouble code (DTC) is a generic powertrain code, which applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The IAT (Intake Air Temperature) sensor varies in resistance based upon the temperature of the engine intake air, typically located in the air intake ductwork and is usually a two wire sensor. 5 Volts is supplied to one wire from the PCM (Powertrain Control Module) and the other is a ground. The powertrain control module (PCM) monitors the change in the voltage supplied to determine air temperature to run the engine at the most efficient conditions possible at that given temperature.

The PCM monitors the change in the 5 Volt supplied to determine air temperature. When the intake air is cold, the resistance is high, resulting in a high signal voltage. When the intake air is warm, the resistance is low, resulting in a low signal voltage. This code means that the PCM saw a larger-than-normal change in a shorter-than-expected time on the IAT2 signal circuit.

What causes the problem of Intake Air Temperature Sensor 2 Circuit Range/Performance?

• Faulty Intake Air Temperature (IAT) sensor and circuit
• Short or broken Wiring and harness related to the sensor
• Poor electrical connection to the Intake Manifold
• PCM being faulty and interpreting wrong readings

1. Air Temperature Sensor - The Air Temperature sensor are usually exposed to air entering the engine and should be replaced if found faulty.
2. Air Intake Kits - It’s important to maintain the proper air to fuel ratio and enable proper functioning of the fuel delivery system. Buy quality air intake kits from us.
3. Air Flow Sensor Connector - Always check for the faulty connectors and replace when found faulty. Buy new connectors from us!
4. Engine Control Module - OBD Error Code P0096 can also be due to faulty ECMs. This may lead to engine stalling or not starting, and check engine lights being on. It’s better to get the faulty electricals replaced as soon as possible.
5. Coolant Temperature Sensor - This sensor is vital for proper functioning of the air intake system, fuel delivery system and the engine performance. Thus, a faulty sensor must be replaced at all cost.
6. Powertrain Control Module - P0096 error code also relates to problems with the powertrain which can store and flash wrong error code. Find all the Powertrain related parts with us.
7. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
8. Turbocharger - It’s a forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber. Replace your old turbochargers with us!
9. Supercharger - Supercharger is an air compressor that increase the air pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing power. Replace damaged supercharger and parts today!
10. Mass Air Flow Sensor - Wrong information sent by the MAF sensor will affect the engine performance adversely as it will not be able to properly read the air entering the system thus hampering the air to fuel ratios directly impacting the engine’s output. Thus, it is advisable to replace them in time.

Since this code is likely points to the problem on the IAT circuit, there may not be any noticeable big symptoms at present and even if there are any can we considered as general problems by the driver. However, the MIL will likely be on and the car may exhibit some drivability problems.

Common Symptoms

The ECM substitutes a 70° F sensor input for the out-of-specification reading for the sensor

If the outside temperature is more than 10° F different from the 70° F the ECM uses as a substitute output, the engine may run rough

The Check Engine Light is illuminated indicating a problem

Clear the fault codes and perform a road test to try and verify failure for the OBD code

• Replace the IAT2 sensor, if found faulty
• Repair or replace the wiring or connection to the IAT2 sensor
• Repair ECM connector or replace the ECM (Engine Control Module)

At Parts Avatar Canada, you can find all the replacement and performance parts you need to get rid of any OBD Code problem at the best prices in the market and from the best brands, for any make and model. Explore now!

The step by step analysis and diagnosis is recommended by a qualified technician using high grade diagnostic tools to check for all the problems and solving them.

• You require a scanner or a code reader and a digital volt ohmmeter to successfully diagnose this code. Begin your diagnosis by visually inspecting all wiring and connectors to the sensor.
• Search for shorted or burned wiring and replace them.
• Connect the scanner to the diagnostic connector and record all stored trouble codes and freeze frame data. After the codes are cleared, operate the vehicle to see if the code returns. If the code fails to immediately return, you may have an intermittent condition.
• Check for the problem with the IAT sensor and circuits and diagnose to see with the error returns.

If everything else is fine, then the problem can be with the PCM. Replace the PCM if required and check if the code reappears.

Common Mistakes When Diagnosing The P0096 Code

Some of the common mistakes done while changing diagnosing the OBD code P0096 are:

• Improper assessment of the IAT sensor failure
• Simply replacing the Powertrain Control Module (PCM) without considering other possibilities of problem.
• Not noticing the damaged or loosened wiring and circuit problems.
