Honda's do not use a mass air flow (MAF) sensor. They use a manifold air pressure (MAP) sensor. The MAP sensor measures vacuum vs the MAF sensor measuring air flow/temperature. No real reason to clean a Honda MAP sensor. Are you having engine performance/idle problems? --------------------------------------------------------------------------------

on top intake plenum in the middle to the back.a sensor with small vacuum line with grey light green orange wires goes to it.check engine light will replace itsself after so many miles after changeing if light is on it will go off also if your check engine light isnt on then i wouldnt replace this part if it were bad check engine light would be on

P0105 - MAP Sensor Circuit Insufficient Activity.If it is the 3.4 or 3.1L engine The Map sensor is located towards the back of the engine by the coil packs.Would verify that it is plugged in and also that the vaccum line going to it is not cracked,If all this checks ok then map sensor may need replaced.

The EGR valve and MAP sensor are indeed different and unrelated parts. An EGR valve that is stuck open can however cause the system to set a false MAP sensor code due to the loss of vacuum in the intake which will cause the sensor to read low but the engine should run very bad, if at all, when this happens. The MAP sensor is located slightly to the drivers side of the throttle body housing on the front side of the motor and is easy to replace. I'd make sure that your EGR valve isn't stuck open or that you don't have another large vacuum leak that could mimic a faulty MAP sensor before replacing it however. Hope this helps a bit and good luck!

on the air filter intake hose

Located on the MASS air flow attatched to the air box

The Manifold Absolute Pressure sensor is located on top of the cylinder head, right side, about 2/3 of the way back. there is one screw holding it in. You will need to take off the plastic engine cover off to access it. The sensor in the airbox is the MAF sensor.

also check he hoses to the map sensor...its a small sensor on the back of the upper intake plenum. Pretty common issue....
