    Nissan Note 2007 - Live data query? codes P2122 & P2138 # Archived Message

    Posted by Luke Browne on June 3, 2010, 10:02 am

    This Nissan came in because the engine light was illuminated. There were no drivability issues just the MIL.
    I plugged it into the KTS and got two codes for the accelerator position sensor as follows:

    -P2122 APP senor 1 malfunction
    -P2138 APP sensor snchronisation error

    Went into live data to see what readings the sensor was giving and it was responding well but both the sensors were giving the exact same voltage (0.7-4.3)? Im not overly familiar with this system but i believed that the redundant sensor should read half the voltage of the first??
    I scoped the APP sensor which showed that one sensor was infact half the voltage of the other??? Now i was really confuse!! Anyone who can shed any light on this indescrepency would be greatly appreciated.

    Cheers
    Luke
