Symptoms
Symptoms of a C2619 diagnostic trouble code may include:
- Malfunction Indicator Lamp (MIL) illuminated
- Carbon Buildup on O2 Sensor
- Poor fuel economy
- 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 :
