How do I fix code P242D VOLKSWAGEN?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P242D VOLKSWAGEN code
The cost of diagnosing the P242D VOLKSWAGEN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P242D VOLKSWAGEN 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.
