P0097 code definition

Intake Air Temperature Sensor 2 Circuit Low Input

What the P0097 code means

P0097 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake air temperature sensor 2 (IAT2) input is lower than the normal sensor range. This typically indicates that there is an electrical short.

What causes the P0097 code?

  • The intake air temperature sensor 2 has a short circuit in the connector, wiring, or the sensor for more than .5 seconds during one drive cycle.

  • The ECM has an internal short circuit in the IAT2 circuit or the connector to the ECM has a short.

What are the symptoms of the P0097 code?

  • The Check Engine Light will come on indicating a problem.
  • The engine may hesitate on acceleration.
  • The engine may run lean or rich depending on outside temperature.

How does a mechanic diagnose the P0097 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 a normal reading.

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

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

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

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

  • Follows pinpoint tests if any failures are found in above tests.

Common mistakes when diagnosing the P0097 code?

Follow these simple guidelines to prevent mistakes:

  • Verify the failure by clearing the code and retesting to see 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 tests or visual testing.

How serious is the P0097 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.

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

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

What repairs can fix the P0097 code?

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

Additional comments for consideration regarding the P0097 code

The IAT2 code P0097 can be caused from a broken or cracked sensor connector or contamination from engine oil or coolant from other leaks. Any kind of sensor, wiring, or connector short circuit will cause this code and may also cause additional codes, such as P0096, P0098, and P0099 depending on the cause.

Exceeded my expectations... The weather knocked my appointment off track a couple of times, but Kinder's constant updates and timely communication made it a non-issue. He Made it to our rescheduled appointment a little earlier than scheduled ready to go. Before beginning any work he explained the process, confirmed what I wanted done and how it worked. Upon finishing.. he test drove vehicle and explained to me "what" he had done and what was discovered causing the issues. He didn't bash my prior mechanics he just explained that some vehicles need a little more knowledge than others...If my long winded comment is any indication... as I stated earlier, my expectations were exceeded. For those of you, like myself , who totally enjoy your European car but not the sometimes sticker shock of maintenance... i strongly encourage you to try this service and I strongly urge you to request Kinder... You can thank me later. Royce
