Symptoms
Symptoms of a U0024 Tvr Tuscan diagnostic trouble code may include:
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
- Faulty PCM
- If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly

Possible Causes :
- Defective ECU strategies or components will prevent proper regeneration
- The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
- An air leak forward of the DPF will change the sensor readings resulting in the code
