@MTKAG Welchen hast du getauscht? P244D bezieht sich auf den Temperatursensor vor dem Kat! Verkabelung auf Kurzschluss zu +12V überprüft?
DTC P244D
Exhaust Temperature Too High For Particulate Filter
Regeneration
Fault Diagnosis and Rectification: particulate filter pre
temperature sensor circuit - Voltage above upper limit
.Refer to electrical circuit diagrams and check particle
filter pre temperature sensor circuit for short to power
The sensor is located at the catalytic converter. The
temperature sensor informs the ECM as to the
temperature of the exhaust gases after they have passed
through the turbo, upstream of the catalytic converter.
The sensor is a NTC type resistor, which measures the
temperature of the exhaust gases. The resistance, and
so the voltage drop at the sensor will alter depending
on exhaust gas temperature.
