2005 Honda Accord LX 2.4L Code P2122 and P2127
 

I'm a new user of this forum and also new honda owner. I just boght a 2005 Honda Accord LX 2.4L which appeared like a great business since it looks in wonderful shape. The check engine light is on, and the scan shows Failure codes P2122 and 2127, which according to my research they are related to the Accelerator Pedal Position Sensor. At fisrt, i thoght the issue was because a bad TPS signal, so i replaced it calibrated as per recommendations, but the problem was not resolved.
I then found something online regarding APPS, and although mii APPS is different to most of the ones i've seen for Accord, i replaced it to perform tests, but didn't fis the problem either.
Finally, i performed a test with another Throttle Body, but its TPS readings are .9 while close and 4.96 Open. the rpm don't behave good either.

The sympthoms are:
Idle rpm too high. Over 1600 rpm. steady.
When i shift from park position to Reverse o Drive position, transmision hits because the high revs and bad readings from sensors.
When accelerate, rpm become unsteady.
After calibrate the TPS, i can move a drive the car, but it doesn't accelerate over 30 mph.

I'd appreciate your expert comments and recomendations.

Thanks in advance.

I have same issue
 

Did you ever fix the problem? What was it?

Did this idle issue ever get resolved? My 2005 accord is seeing the same issues.
