Question about 2004 Honda Accord
that code means there is a fault at the bank 2 oxygen sensor.
as you stand at the frond of the car and look into the engine bay, the sensor is fitted to the middle of the exhaust manifold nearest to you. disconnect the wires on the plug, and i think it is a 22mm spanner or deep socket to remove it.
there are various proprietary oxygen sensor cleaners on the market, but there is no certainty that this will work. there could be an actual fault with the sensor, or it may be too dirty to clean.
if finances permit, i would recommending changing the sensor as a matter of course.
the ecu fault reading can be reset by removing the battery -ve lead for 30 minutes.
make sure you have the radio code before doing this as you will need to reset this as well.
if you only clean the sensor and the fault reading comes back, then you will have to change the sensor and reset the ecu again.
hope this helps.

2004 honda accord with a code p2240, this code means the front air fuel sensor has high voltage, take note that there are two front sensors one on each manifold, the bad one is bank 2 sensor 1. Cleaning will not help this problem, you will need to check the wiring to the sensor and also check the connector to this sensor and if all looks good then just replace the sensor. the diffrence between an air fuel sensor and oxygen sensor is that the air fuel sensor does alot more than an oxygen sensor and costs more, the newwer cars use this air fuel sensor, they both look alike but are wired difrently.the location of this sensor is the front manifold sensor, look behing the radiator and you will see it going into manifold, good day.
