Just like any other car component, these sensors may malfunction over time due to various reasons. Thankfully, vehicles are equipped with on-board diagnostic (OBD) systems to help you or a mechanic identify possible issues in your vehicle, including faulty sensors.<\/p>\n\n\n\n<p>OBD-II code P0097 is related to a possible fault in one of your vehicle&rsquo;s intake air temperature (IAT) sensors. Here is some helpful information about it.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P0097 Code Mean?<\/h2>\n\n\n\n<p><a href=\"https:\/\/www.carparts.com\/blog\/search-obd2-codes-list\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Diagnostic Trouble Code\">Diagnostic Trouble Code<\/a> (DTC) P0097 stands for &ldquo;IAT Sensor 2 Circuit Low (Bank 1).&rdquo; It is triggered when your vehicle&rsquo;s powertrain control module (PCM) perceives an irregularity in the intake air temperature #2 readings.<\/p>\n\n\n\n<p>To be specific, this code may be logged once the PCM detects that the air temperature reading in sensor #2 is unusually high (causing low voltage resistance) when the engine temperature is low. Bank 1 refers to the side of the engine that contains the #1 cylinder.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool-1024x683.jpeg\" alt=\"man using car diagnostic scan tool\" class=\"wp-image-18235\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/man-using-car-diagnostic-scan-tool.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption> Code P0097 may register when your vehicle&rsquo;s powertrain control module perceives an irregularity in the intake air temperature #2 readings.&nbsp; <\/figcaption><\/figure>\n\n\n\n<p>In order to fully understand this code, let&rsquo;s discuss the basics of an intake air temperature sensor. This device is used to monitor the temperature of the air that enters the engine. It measures air temperature with the help of an internal thermistor or a thermometer that sends voltage signals to the PCM.<\/p>\n\n\n\n<p>When the air temperature is cold, the resistance in the thermistor should be high. However, when the air is warm, the resistance should proportionally decrease. This data is used by the PCM to determine the temperature of incoming air.<\/p>\n\n\n\n<p>Once the PCM detects an air temperature reading that&rsquo;s unusually high (which means low resistance) when the engine temperature is unusually low, it will trigger the error code.<\/p>\n\n\n\n<p>Read our advanced technical discussion about the <a href=\"https:\/\/www.carparts.com\/blog\/p0113-code-intake-air-temperature-sensor-1-circuit-high-input\/#What_is_an_Intake_Air_Temperature_IAT_Sensor_and_How_Can_It_Cause_P0113\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"intake air temperature sensor\">intake air temperature sensor<\/a> and how it can cause OBD codes like P0097 to appear for more information that can help you resolve the issue.<\/p>\n\n\n\n<p><strong><em>Note:<\/em><\/strong><em> The definition of code P0097 may be different depending on the vehicle manufacturer.
