Fault Codes:
Hyundai HX220 NL EPFC 3313（4765-4）
Fault Description:
Aftertreatment diesel oxidation catalyst intake temperature sensor circuit -Voltage below normal or shorted to low source. Low signal voltage detected at the catalyst intake sensor circuit. The inlet temperature sensor circuit of the post-treatment diesel oxidation catalyst - the voltage is lower than the normal value or short-circuited to the low power supply. The signal voltage of the sensor circuit at the catalytic converter inlet is detected to be too low.
Fault Location:
Possible reduced engine performance. It may lead to a decline in engine performance.
