Fault Codes:
Hyundai HX220 NL EPFC 3314（4765-3）
Fault Description:
Aftertreatment diesel oxidation catalyst intake temperature sensor circuit -Voltage above normal or shorted to high source. High signal voltage detected at the catalyst intake temperature sensor circuit. Post-treatment diesel oxidation catalytic converter inlet temperature sensor circuit - voltage higher than normal value or short-circuited to high power supply. The signal voltage of the catalytic converter inlet temperature sensor circuit is detected to be too high.
Fault Location:
Possible reduced engine performance. It may lead to a decline in engine performance.
