P0097 - OBD Trouble Code

<<See All OBD Codes

The major signs of problem indicating OBD Error Code P0097 can the Check Engine Light On, increase in the fuel consumption, smoke from the tailpipe and increased heat level indications.

This code indicates that the PCM has detected a voltage reading that is out of the normal range for the intake air temperature sensor 2 circuit.

The IAT (Intake Air Temperature) sensor measures the temperature of air that is entering the engine. Intake air temperature is important because the higher the intake air, the higher the combustion temperatures. High combustion temperatures result in increased NOx (Nitrogen oxides) emissions.

The change in resistance changes the 5 V reference from the PCM (Powertrain Control Module), thus informing the PCM of the temperature of incoming air. If the PCM notices that the incoming air temperature Sensor 2 is unusually high, when the engine temp is still relatively low, it will set a P0097 and will be stored and flashed by the PCM, illuminating the Malfunction Indicator Lamp (MIL).

What causes the problem of Intake Air Temperature Sensor 2 Circuit Low Bank 1?

• Lack of reference voltage to IAT sensor due to open wiring.
• Increased high intake air temperatures
• Signal circuit is short to ground
• IAT connector are damaged
• Faulty PCM that requires replacement or reprogramming

1. Air Temperature Sensor - The Air Temperature sensor plays a crucial role in the performance of the engine. Replace faulty sensor now!
2. Air Intake Kits - It is important to maintain the proper air to fuel ratio and enable proper functioning of the engine with the help of air intake systems. Buy quality air intake kits from us.
3. Air Flow Sensor Connector - Air intake to the engine control unit is detected by this sensor and if the connector is damaged, if will influence the performance. Replace faulty connectors with us!
4. Engine Control Module - OBD Error Code P0097 can be indicated by engine stalling or not starting, and check engine lights being on which can also be due to faulty ECMs. It’s better to get the faulty electricals replaced as soon as possible.
5. Powertrain Control Module - P0097 error code also relates to problems with the powertrain that is not able to generate response in time causing distorted engine timing. Find all the Powertrain related parts with us.
6. Diagnostic Tool - Detect the OBD error code by using professional diagnostic tools. Buy them from us now!

This P0097 error may cause reduced power, the engine may run rough, or the engine may crank but not start. There is typically an illuminated Check Engine light as well. At Parts Avatar Canada find genuine replacement parts and performance parts for your vehicle available for all makes and model be it Volvo, Chevrolet, Ford, Dodge, Porsche, Ford, Land Rover, Audi, Hyundai, Fiat, etc. This error may also indicate problems that will likely affect:

Common Symptoms

• The Check Engine Light On
• Engine hesitant on acceleration.
• Engine may run lean or rich
• Rough engine idle and throttle response

• Clear the fault codes and perform a road test to try and verify the failure/fault
• Replacement of the IAT sensor 2 if faulty
• The wiring, or connection short to the IAT2 sensor should be replaced/repaired
• Replacement of ECM (Engine Control Module)

A qualified technician should be hired to attend to the OBD error code problem who can use professional scan tools efficiently and can therefore diagnose the problem with ease. Following are the steps:

• Visually inspect the electrical connections and wire harness to the IAT sensor.
• Clears codes and verifies if the code returns by doing the test run under the same circumstances in which the code appeared.
• Use an OBD-II scanner to scan the IAT sensor 2 and compares the output to be within specifications compared to a normal reading.
• IAT sensor 2 connector is disconnected and verified for the temperature reading and see if it goes below -4° F.
• The two connector wires are shorted together to see if temperature readings go above 212° F.
• Uses a multimeter and check the resistance of the IAT sensor 2 to be within specifications.
• Replaces the sensor if the sensor is found faulty. Also check for the PCM faults and errors.

Common Mistakes When Diagnosing The P0097 Code.

Follow these simple guidelines to prevent mistakes:

• Not examining the IAT sensor failure
• Changing the Powertrain Control Module (PCM) without checking other problems.
• Not checking for damaged or short wiring and connectors.
