Check Engine light on and am pretty confused!
So after dropping someone off at home today I had a little problem. I went to pull away and the check engine light and wrench light(I know the light comes on to prevent any further damage) came on and then the car died. I started it back up and immediately both lights came back on but it doesn't die this time so i limp home so I didn't have to get it towed. I had been driving normal the entire time and didn't even exceed 40 mph. Does this sound like a bad tune(I think it might be)? Or possibly the stock TB isn't cutting it anymore? I have a Whipple Intercooled HO Kit with the car making 530 whp(with a fully built engine). The code on my SCT was P2135 and said throttle/pedal position sensor/switch a/b voltage correlation. I didn't have time to go to Ford today and will go tomorrow so just seeing if anyone might know whats going on here.

there are 2 switches in the pedal that use inverse voltage, one starts high and one starts low, as the pedal is depressed the highter voltage lowers and the lower voltage raises. the pcm checks a table to make sure it is getting correct info from the pedal. if it sees a bad signal it sets a code and limits throttle. this is to prevent a toyota wide open throttle event.
cleaning the throttle body wont help your problem, and your tune shouldnt be at fault. most likely a bad pedal sensor.
