Looking for some help. I have a CEL.

Changed purge valve and gas cap. Only the SEL light went away. It is still running DMTL codes. Changed the DMTL and CEL went away but came back after driving ~5 miles. Also have code for low pressure with turbos.

Anyone can help? Attached is a photo of the codes.

Could be a leak detection pump failure. If your car is a PZEV sold and registered in California, at 111K miles those should still be covered under the 15-year 150K mile CARB PZEV emissions warranty.

This video has different error codes, but this is the DMTL pump. Yours may also be related to the control circuit if it could not activate the pump.
