2004 Toyota Sienna: V6..Check engine light is flashing. Checked codes

Customer Question

2004 Toyota Sienna V6. Check engine light is flashing. Checked codes - No Codes. Try to clear the check engine light and it comes back on flashing. Check engine light was solid and indicated that I needed to change the O2 sensors and the spark plug coils. That was done. After the O2 sensors were changed, the check engine light started flashing. Found that there was a gasket cap that was melted so we replaced it and the car is running perfectly. No Misfires - Just a Flashing light and I can't get it smogged because of this. Any suggestions?
