Bank 1 points to the side of the engine opposite 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\/obd-code-p0110-1024x683.jpeg\" alt=\"obd code p0110\" class=\"wp-image-18504\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/obd-code-p0110-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/obd-code-p0110-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/obd-code-p0110-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/obd-code-p0110-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/obd-code-p0110-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/obd-code-p0110.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Code P0110 is triggered when the PCM perceives that the signal from the intake air temperature (IAT) sensor circuit does not match factory specifications. <\/figcaption><\/figure>\n\n\n\n<p>The IAT sensor is a negative temperature coefficient (NTC) thermistor that decreases in resistance as the temperature of the sensor increases. Its purpose is to measure the temperature of the air entering the engine and provide this data to the PCM.<\/p>\n\n\n\n<p>The information provided by the IAT sensor (along with various other sensors) is used by the PCM for fuel control and ignition timing. If the PCM detects that the signal it has received from the IAT sensor might be out of normal operating range, it will log trouble code P0110.<\/p>\n\n\n\n<p>If you want to learn more about the IAT sensor, you can read our technical discussion about <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=\"how it can cause OBD codes like P0110 to get logged\">how it can cause OBD codes like P0110 to get logged<\/a>.

A thermistor built in the sensor changes the resistance value according to the intake air temperature. If the ECM detects the DTC &ldquo;P0110&rdquo;, it operates the fail&minus;safe function in which the intake air temperature is assumed to be 20&deg;C (68&deg;F).<\/p>\n\n\n\n<p>Code P0110 may appear on some Toyota vehicles. On a 1998 Toyota Camry LE 3.0L V6, for example, this DTC can be caused by the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Open or short in intake air temperature sensor circuit<\/li><li>Issue with IAT sensor (built into mass air flow meter)<\/li><li>Problem with ECM<\/li><\/ul>\n\n\n\n<p>After confirming DTC P0110 use the OBD II scan tool or TOYOTA hand&minus;held tester to confirm the intake air temp. from &ldquo;CURRENT DATA&rdquo;.

However, it may be difficult to pinpoint the exact cause of the problem. There are many possible triggers associated with this code.<\/p>\n\n\n\n<p>Keep in mind that the diagnostic and repair steps for this code will vary depending on the specifications of your vehicle. As all cars are built differently, they may require varying diagnostic processes.<\/p>\n\n\n\n<p>For instance, a P0110 code on a <a href=\"https:\/\/www.carparts.com\/air-temperature-sensor\/toyota\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Toyota\">Toyota<\/a> may be diagnosed differently from a code P0110 on a <a href=\"https:\/\/www.carparts.com\/air-temperature-sensor\/nissan\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Nissan\">Nissan<\/a>. This is why it&rsquo;s important to refer to a repair manual before troubleshooting your vehicle. But if reading it has only left you confused, it might be best to leave the job to an expert.<\/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\/low-gas-mileage-1024x768.jpeg\" alt=\"poor gas mileage\" class=\"wp-image-18506\" width=\"1024\" height=\"768\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-gas-mileage-1024x768.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-gas-mileage-300x225.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-gas-mileage-768x576.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-gas-mileage-928x696.jpeg 928w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-gas-mileage-150x113.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-gas-mileage.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Poor gas mileage is a common symptom of code P0110.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix the P0110 Code<\/h2>\n\n\n\n<p>The P0110 code may share similar triggers and symptoms with other DTCs.
