The RAM P203F Code is a warning that appears to alert the driver that the Diesel Exhaust Fluid (DEF) tank is too low. This message is generated when the DEF tank level is at approximately two gallons, and the customer will hear a chime and get an EVIC message reading “DEF Low REFILL Soon”. If the tank level becomes lower, the customer will hear another chime, and get an EVIC message that reads “Speed Limited to 5 mph in XXX MILES Refill DEF”. This indicates that the DEF tank is at its minimum level of 0.7 gallons before the car will be limited to 5 mph. To prevent this warning from occurring, it is important to keep the DEF tank filled, as a minimum of two and a half gallons of approved Diesel Exhaust Fluid should be added to the tank.
Causes and Solutions of the RAM P203F Code
| Cause | Solution |
|---|---|
| DEF Tank Low | Add a minimum of two and a half gallons of approved Diesel Exhaust Fluid to the tank |
| Speed Limited to 5 mph | Fill the DEF tank to the minimum level of 0.7 gallons |
| EVIC Message Reading “DEF Low REFILL Soon” | Check the DEF tank level when the message appears and refill it if necessary |
| EVIC Message Reading “Speed Limited to 5 mph in XXX MILES Refill DEF” | Fill the DEF tank with approved Diesel Exhaust Fluid to prevent the speed limit |
What is the RAM P203F Code?
The RAM P203F Code is an indication to the driver that the Diesel Exhaust Fluid (DEF) tank is at a low level and needs to be refilled. It is triggered when the tank is at approximately two gallons, and the customer will hear a chime along with an EVIC message reading “DEF Low REFILL Soon”. If the DEF tank level decreases further, a second chime is heard and an EVIC message reads “Speed Limited to 5 mph in XXX MILES Refill DEF”. This indicates that the DEF tank is at its minimum level of 0.7 gallons before the car will be limited to 5 mph.
What Causes the RAM P203F Code?
The RAM P203F Code is generated when the DEF tank is low and needs to be refilled. When the tank is low, the customer will receive an EVIC message reading “DEF Low REFILL Soon”. If the tank is at its minimum level of 0.7 gallons before the car will be limited to 5 mph, the customer will receive the message “Speed Limited to 5 mph in XXX MILES Refill DEF”.
What Solutions are Available for the RAM P203F Code?
The solution to the RAM P203F Code is to add a minimum of two and a half gallons of approved Diesel Exhaust Fluid to the DEF tank. If the tank is already at its minimum level of 0.7 gallons, the customer should fill it with approved Diesel Exhaust Fluid to prevent the car from being limited to 5 mph. Additionally, it is important to check the DEF tank level when the message appears and refill it if necessary.
Conclusion
In conclusion, the RAM P203F Code is a warning that appears to alert the driver that the Diesel Exhaust Fluid (DEF) tank is too low. To prevent this warning from occurring, it is important to keep the DEF tank filled, as a minimum of two and a half gallons of approved Diesel Exhaust Fluid should be added to the tank. If the tank is already at its minimum level of 0.7 gallons, the customer should fill it with approved Diesel Exhaust Fluid to prevent the car from being limited to 5 mph. It is also important to check the DEF tank level regularly and refill it if needed to avoid the RAM P203F Code.
