The bank 1 sensor 2 for a 2004 Honda Accord is going to be located on the catalytic converter and in the south downstream area of it.. This will need to be accessed from underneath the car and You will need to put it up on a jack. A 2 ton jack will be more than sufficient for this job. The replacement sensor will cost between $30 and $50. If You decide to take it in to a mechanic to have them do this job for You the entire cost of parts and labor shouldn't be more than $300.
