Fault Codes:
Hyundai HX220 NL EPFC 1881（3251-4）
Fault Description:
Aftertreatment diesel particulate filter differential pressure sensor circuit -Voltage below normal or shorted to low source.Low signal voltage or open circuit detected at the aftertreatment differential pressure sensor circuit. Post-treatment diesel particulate filter differential pressure sensor circuit - voltage lower than normal value or short-circuited/open-circuited to ground. The signal voltage of the post-processing differential pressure sensor circuit is detected to be too low or open
Fault Location:
possible reduced engine performance. It may lead to a decrease in engine power
