I have a customer's 07 LMM C5500 that they brought to me with a p2138 code.
I went through the diagnostic tree, all checks out good. I am getting correct voltage ranges on Accelerator Pedal Position Sensor Voltage 1=.9v-4.2v and Sensor Voltage 2= .5v-2.2v
They put a new Accelerator Pedal and Sensor assembly in before bringing it to me...
But Accelerator Pedal Position (D)= 18.4%-84.7%
Accelerator Pedal Position (E)= 10.6%-43.5%
How can the voltage sweeps be correct but % be wrong???
