Help with P0455 on Cadillac DTS

Question

I’m looking to replace several of the P0455 system related sensors on our 2008 DTS, since the problem is new and our vehicle is ten years old.

Could you please show me where these sensors are found and approximate cost of there repair/replacement? I’ve been looking online and haven’t been able to find the exact match for my situation. Any help would be greatly appreciated!!!

Thanks again...Nick

Answer 1

Here is a list of the most likely components that could trigger the P0455 code, so you can start with those components and clear the code. I hope that is your question and that helps you fix the problem.

- Gas Cap
- Evap Purge Solenoid Valve
- Evap Canister Vent Solenoid
