I am having a little trouble finding some information related to the pedal position sensor for my 2007 Ford Mustang Shelby GT (4.6L). From what I understand there are 2 sensors and each sensor must output voltage within a specific range at rest and when fully depressed. My car went into limp mode during my last run at the auto-x test and tune saturday and threw codes P2121, P2124 and P2132. All seem to be related to this position sensor on the accelerator pedal. I've hooked my laptop up to my car and using the livewire software I can monitor the voltages of both sensors while pressing and not pressing the gas. However, I cannot seem to find what the VALID ranges should be. I only ask because the sensor is part of the gas pedal itself and to replace it, I have to replace the entire pedal/sensor assembly. I know it's an obscure question, but if someone knows, fire away...

I don't know the voltages you are needing but I've heard of plenty of issues with the throttle body going bad. It may be worth checking in to as I'm sure it's linked to those sensors in some form as well.

I think it's suppose to be between .9 and 1.0 volts. I can tell you for sure tomorrow.

The throttle body is kenne bell's stage 2, but it still could be related to it.

horspwr, the voltage you are referring to, can you tell me which of the two sensors #1 or #2 you are referring to and if this is at rest or depressed? If this is the voltage at either state for #1, I believe that #2 should be the 5v - #1 or something along those lines. In any case, thanks to you guys for helping out.

I went ahead and ordered the pedal assembly anyway, should be here tomorrow. <fingers crossed>
