Test Honda APP Sensor
 

I own a 05 Honda Accord LX 2.4L, which is having issues related to codes P2122 and P2127. According to my researchs, both codes are associated to the Accelerator Pedal Position Sensor. I´d like to test this sensor in order to confirm it is really a problem of a sensor malfunction or maybe because the harness, conector or wiring. I´d appreciate any advice for a procedure to test the APP sensor. Thanks.

There are several pages of testing procedures, I'd suggest you get a copy of the service manual. I could try to copy all of them out but it would get messy.

Also note that there is different tests for the 05 and newer than there is for the 04 and older.
