I do not have access to your email address,
That could be an EVAP hose off, or the leak detection pump but the tests would have to be done to determine where the problem is.
I can get the test instructions for it and put it in a PDF file, (it is rather large) and send it to your email address for as little as is allowed.
You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it, Thanks
I could guess if that is what you want. There is no way to know which part is bad without testing it or replacing parts, (purge valve, LDP, etc) until the code doesn't reset. In fact there has been a factory service bulletin on diagnosing the EVAP system and related components.
Yes, With the purge valve, and the leak detection pump, the tests include.
Checking internal resistance
Checking voltage supply
