What is the code P0455 on a Dodge Stratus?

The code P0455 on a Dodge Stratus indicates a large leak in the vehicle’s evaporative emission control system. The EVAP system is responsible for capturing fuel vapor from the fuel tank and sending it to the engine’s intake for combustion. When there is a large leak in the EVAP system, the P0455 code is triggered.
Some common causes of the P0455 code include:
– A loose or missing gas cap
– An improper gas cap that has been installed
– Damage or leaks in the EVAP system, such as hoses or the canister
– A fuel filler cap that failed to close properly
– A leak within the fuel tank.
To fix the issue, you can try the following steps:
1. Reinstall the gas cap, ensuring it is tightened properly.
2. Clear the code by disconnecting the battery for about 30 minutes.
3. Drive the vehicle for a few days to see if the code comes back on.
If the code persists, it is recommended to have a professional mechanic perform a visual inspection of the EVAP system to check for any obvious leaks. They may also conduct a smoke test to identify any hidden leaks. If no leaks are found, there may be a sensor issue that needs to be tested according to the manufacturer’s instructions.
Please note that the cost to diagnose and repair the P0455 code can vary depending on factors such as the location, make and model of the vehicle, and the engine type. It is best to consult with a qualified mechanic or auto repair shop for an accurate estimate.
