p2135 code Help !!!
Hi guys, can someone put in the right direction regarding this corvette of mine its a 2013 6.2 liter base model and it went into reduced engine power mode/ service stability control message on dash and i had no power. Put solas scanner on it and code p2135 displayed on scanner saying throttle/pedal position sensor malfunction, i replaced the throttle body and sensor thinking that was the issue and cleared the code, car ran good for about 20 minutes then went back into limp mode again and showing code p2135 throttle/pedal position malfunction. Was told by someone i might need to get the computer flashed or reset at gm dealer? Anyhelp is greatly appreciated...thanks

That code can be set by high or low voltage to the sensor. Is it possible that a pin is bent at the connector or a wire is loose or broken at the connector.
That is where i would look first and foremost.
My son had the same issue with an O2 sensor, and it was a bent pin inside the connector..
Good luck

I'm not sure, but because it is electronically calibrated to a set closed and fully opened throttle, it may have to retrained with a TECH II
Hopefully, someone can chime in on that.
Good luck

Check the connector and the wires going to (about and inch from connector). A lot of times they get bent and break inside (so you don't see them) and or severely hampered. Look at all the pigtails they sell for these. A lot times also the connectors look fine but are actually loose when you put the plug in them but you could never tell as you are putting all 6 in at once. I have some male end connectors and put them in individually and one of the inputs was loose. At the end of the day I ended up putting a new pigtail in after buying a bunch of stuff.
