I have a 2002 honda accord that the check engine light will come on for a few days and then go off for a week. I carried it to the dealer and they wanted approximately a $100 to hook up to their computer and tell me what was wrong. The day I went to do this, of course the light wasnt on and they said it may or may not give them a code. After a month of the light on and off again, I bought a diagnostic scanner and came up with the following code. P0135 sensor heater circuit malfunction bank 1 sensor 1. I am not sure what to do with this. Is this the oxygen sensor or related item, or what else? I have worked on cars for 20 or so years, but they are harder to figure out without the manual. Any help on this would be apprecated

That's not usually a code that comes on intermittently. So I would check the primary o2 sensor connector pins first. (along with the rest of the connectors back to the ecu)
