I have replaced the entire full pump which also had a new sensor on it. Then figured why not as I bought the car used for my daughter and wanted to replace fuel strainer as well. I can clear code by removing battery but after about 7miles driving it appears again. When I put my OBD on to read code it will show PENDING or COMPLETE. If PENDING within about 7 mins of engine just idling it will go to COMPLETE. What else can I look at to get this code to go away? I am wondering if it is stuck in the ECU to throw the code and if so how can I clear the ECU?<\/p>\n<hr \/>\n<p>RESPONSE<\/p>\n<p>The reference 5V in the PCM is supplied to the fuel temperature sensor via a resistor in the PCM. That resistor in the PCM and the thermister in the fuel temperature sensor are connected in series. When the resistance value of the thermister in the fuel temperature senor changes with variations ion the fuel tank temperature, the output voltage also changes. So there may be an issue with the PCM or more likely the the wiring. Look for damaged wiring, <strong>poor connections<\/strong> and or corrosion. The repair must be made before the code can be cleared.<\/p>\n<p>If the fuel temperature sensor&#8217;s voltage is less than 0.1V after starting, the PCM determines that a fault exists and a <a href=\"\/\/www.freeautomechanic.com\/diagnostictroblecodes.html\">Diagnostic Trouble Code (DTC)<\/a> is stored.<\/p>\n<h3>KIA Code P0182 &#8211; Fuel Temperature Sensor Circuit Low Input<\/h3>\n<div class=\"desc\"><strong>KIA Code P0182 Description<\/strong><\/div>\n<div class=\"info_code\">\n<p>The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank.
