P0096 code definition

Intake Air Temperature Sensor 2 Circuit Range/Performance

What the P0096 code means

P0096 is the OBD-II generic code indicating that the engine control module (ECM) has determined that the intake air temperature sensor 2 (IAT2) is not operating in the normal sensor range and the ECM cannot use the sensor output to determine intake air temperature.

What causes the P0096 code?

The intake air temperature sensor 2 is not accurate within 2 degrees when compared to the engine coolant and mass air temperature sensors. This can happen when the engine is cold started after the engine has been off for more than 5 hours.

The intake air temperature sensor 2 is not within specification range within 2 degrees for the sensor when compared to the mass air flow sensor when started warm and heat soaked from 10 seconds to 30 minutes.

What are the symptoms of the P0096 code?

  • The ECM will substitute a 70° F sensor input for the out-of-specification reading for the sensor.

  • The engine may run rough or hesitate if outside temperature is more than 10° F different from the 70° F the ECM uses as a substitute output.

  • The Check Engine Light will be illuminated indicating a problem.

How does a mechanic diagnose the P0096 code?

  • Visually checks the electrical connections and wire harness to the intake air temperature sensor.

  • Clears codes and verifies if the code returns.

  • Scans the IAT2 sensor and compares the output to be within specifications compared to the IAT in the mass air sensor to be within 2° F.

  • Disconnects the IAT2 sensor connector and verifies the temperature reading goes to below -4° F.

  • Shorts the two connector wires together to see if temperature readings go to above 212° F.

  • Uses a multimeter to check whether the resistance of the IAT2 sensor is within specifications.

  • Replaces the sensor if the sensor is not within specifications.

Common mistakes when diagnosing the P0096 code

Follow these simple guidelines to prevent mistakes:

  • Verify the failure by clearing the code and seeing if the problem is still present.

  • Follow pinpoint tests step-by-step to isolate the failure of the IAT system.

  • Do not replace any parts unless directed by the pinpoint test or visual testing.

How serious is the P0096 code?

  • The engine can hesitate and have a lack of power during acceleration.
  • The engine may fail emission testing.
  • Continued use in a failed state can cause the engine to get carboned up.

What repairs can fix the P0096 code?

  • Clearing the fault codes and perform a road test to try and verify failure
  • Replacing the IAT2 sensor if it fails testing
  • Repairing or replacing the wiring or connection to the IAT2 sensor
  • Repairing ECM connector or replacing the ECM

Additional comments for consideration regarding the P0096 code

The IAT2 code P0096 can be caused from a broken or cracked sensor connector or contamination from engine oil or coolant from other leaks.

The ECM can substitute this sensor output with the IAT sensor 1 on some models and the engine may run normal except for the Check Engine Light being on.
