P0182 Fuel Temp Sensor A Circuit Low Input

Bottom of Form

Study Guide and Component Location Study Guide and General Description Study Fuel Temperature Sensor is NTC thermistor installed in fuel supplying line. It Study senses the temperature of fuel supplied to high pressure pump. Study Fuel temperature is limited (engine power is limited) to keep fuel temperature from reaching at 120°C. This Study limit is to protect fuel line such as high pressure pump and injectors from damages due to rapid deterioration by vapor-lock phenomenon which can occur at high temperature or destruction of oil membrane. Study Guide and DTC Description P0182 is set when the voltage below 0.053V - minimum voltage of FTS output - is detected for more than 2.0 sec.. This code is due to short to ground in FTS signal circuit. Study Guide and DTC Detecting Condition Item Detecting Condition Possible Cause Study DTC Strategy   • Voltage monitoring • FTS circuit • FTS component Study Enable Conditions • IG KEY "ON" Study Threshold Value • When output signal is below the minimum value.(below 0.053V)   Study Diagnostic Time • 2.0 sec.
