Code P242D Audi Description

This fault code is stored in the Engine Control Module (ECM) when a malfunction with the Exhaust Gas Temperature Sensor (EGTS) is detected. Manufacturers may use multiple temperature sensors to monitor the exhaust gas temperature during diesel particle filter regeneration, NOx accumulator regeneration, to ensure the catalytic converter is up to operating temperature and that components will not be damaged by over-heating. The control module can carry out a plausibility check to self-test each temperature sensor. The sensor can be a Negative Temperature Coefficient (NTC) or a Positive Temperature Coefficient (PTC) thermistor.
