CEL but no code - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hello everyone!

my 2011 LLT is throwing a CEL with no code.
i tried scanning with my phone, and afterwards autozone , but it is the same
my inspection has expired and i need this fixed asap =\

I have tried the following
- Used Fuel system cleaner
- Replaced Gas Cap
- unplugged battery for 8 hrs
- cleared codes via phone
- flashed to original and back to my IPF tune (nothing has changed since last inspection last year)

So after about 60 miles of driving, the CEL comes on, and 6/8 ready lights are on.

any ideas? any help would be appreciated, the folks @ IPF are not getting back to me :(

Good luck getting a quick response from IPF. I had that evap code and it was a hose that was cut and it was throwing the code. Once I found out what it was replace the hose no more issues.

Can You monitor the Fuel Tank Pressure Sensor (FTPS)? It should read 0 inches with the gas cap loose.

No other lights are on, wheee is the evap solinoid?
Hmm idk how to monitor the ftps? Any recommended apps? I have dashcommander for the phone

i replaced the evap purge solenoid , it was $50 from dealership , took me 2 mins to swap out.
I flashed it to the older tune that i had a problem with where the car's CEL did not come on but none of the smog monitors went into ready. its been 135 miles its doing the same. I am going to give it another 100 miles and flash back to the newer tune where the CEL had occurred with no code.

any other advice is truly appreciated

Thank You!
