2010 Xterra, No throttle response, no DTC codes set I'm getting the correct output voltages from the pedal and the throttle motor operates during the key on self check but only about 1.9 volts output. I am getting full battery voltage input from the IPDM to the ECU from the throttle motor relay.
I fix the same problem on a 2010 Frontier by replacing and programming the TCM module, the one inside the transmission. Make sure all the wires to the transmission are not shorted or open. Make sure there is no coolant mix with transmission fluid. Good luck.
