[mikerrudy]

I have a c6 2005 corvette that has thrown a code P2135, the problem is when jumping on gas pedal a three warnings come up on dash, check engine, check traction control, reduced,, gas cap has been replace engine power. Throttle body has been replaced, accelerator pedal assy has been replaced. If battery is disconnected codes go away, car runs good until accelerator
pedal get hard acceleration all warnings come back on and car goes into limp mode.

I need an expert mechanic that can help straighten this out, I'm at my wits end trying to figure this out. Hanas Chevrolet was useless they wanted to replace everything.

'86 vette would throw a code occasionally due to a failed speed sensor, (I think this showed up as a traction control error) this affected several systems, you did not mention checking the speed sensors if your year uses the same type of equipment. Full disclosure I am a Ford man, but my wife had the 'vette.

i worked for ford for 36 years now my stepson who works for GM gets me better deals for truck suv etc

my vette problem sounds familiar to yours. Hanas chevrolet wanted $3500 to look for fix and replace multiple parts.

You can get a lot of information from (car) Corvette forums which may help narrow down the issue/s. I know various car forums I have subscribed to have helped greatly.
Quick google search I found this Corvette forum and searched P2135 and ran across this one thread. It talks some wiring issues so hopefully previous owners did not do some splicing in of “mods” causing your issue. I am sure there are others.

I don't know how far you are willing to drive for repairs but there is a Corvette repair shop in Sarasota. They have been in business for a number of years and have, from what I can find, a good reputation. It is S&S Corvettes, 800-886-5064. One of the guys in the business does videos on Corvettes and puts out a lot of good information. I've never had any work done there so I can't provide any personal experience.

Tough one to troubleshoot. Does it exhibit the same behavior with gradual acceleration to full throttle or is it only when you slam the accelerator pedal? If only when you slam the pedal check your Engine mounts.

A couple things stick out -

JUMP ON. if you do this when it's "cold" it's supposed to throw a code and put the limiters on. typically 4 starts will clear it.

If it's when it's warmed up, most times it's a reprogram first not parts replacement. This typically 'realigns' the sensors.

Nahas is good at some things but not everything. Most Chevy dealers (except for Stingray Chevrolet down by Plant City) rarely has much more than 1 "expert" Vette guy, and I use the term loosely.

I'm not a fan of the west coast Vette guys, however if you call Rodgers in Orlando they can or call Corvette Masters in Orlando, I used him once with my C6, the shop is excellent, so much so it's like getting a doctor's appointment.

Use a diagnostic tool to check Throttle Position Sensor first.

Check out Throttle Position Sensor with a diagnostic tool.

If it's like most computer controlled throttles there's a relearn procedure to perform. Lots of times it's something that can be done by the car owner at home.
