I bought a 2004 Honda CRV last week and a day later the check engine light came on, but went off again by the time we went to dealer. They said they could not retrieve a code. The light came back on 2 days later and we went straight to AUtozone to have them run the code, which came back as follows:

BBA/F sensor 1 heater system malfunction
Probable Cause
BB1.-open or short circuit condition
BB2.-poor electrical connection
BB3. Faulty A/F sensor 1

The light has since turned off.
Before going back to dealer I want to know more so that I dont get the runaround. Do these codes indicate that the A/F sensor 1 definitely needs replacing? Is the Sensor #1 the one before the cat. converter? Thank you in advance!
