HiCustomer

The cap is only a small part of the EVAP system, but for tthe monitor to run successfully providing that this monitor is not being blocked by another problem, it should take 2 twenty minute drive cycles under varying driving conditions to set to OK.

Thanks in advance for your ACCEPT and POSITIVE feedback,

Ron, it turned out that what was holding me up was that the test of the evap. system won't run if the gas tank is full. (It has to be below 85%. I found that out online after your message.)

It would have helped to tell me that if you knew. Just FYI.

Oh, I knew it, I just didn't know you had a full tank.

Thanks again,

Ron
