how can i fix?? i think it means primary Heated Oxygen Sensor Circuit Low Voltage?? or even high voltage?

 

Code 1: "Oxygen Sensor "A" (Primary) defective circuit or unplugged / defective sensor "

If you have a Voltmeter, you can check for the signal (if any) the sensor is giving and check for shorts in the circuit. But chances are it just went bad and needs to be replaced...

how much does a primary o2 sensor cost? i hear they cost alot, are they only available at the honda dealer? TIA

 

The good news is that it's relatively easy to replace. But I think they do cost about $150-200 from Honda though...

Try http://www.hparts.com first. They usually have the lowest prices on OEM parts, and you won't pay sales tax...
