Engine Codes: P2135 and P2137
Well, it happened again this morning - started up the car and I pulled out, engine light + "service traction control - reduced engine power"
Car stalled and when I started it back up, same mode, but the idle was ROUGH. bouncining between 700-1200 rpms. I turned of the car and it sounded BAD as the engine came to stop - bery bumpy and a bit loud.
Wasn't sure what to do - didnt wanna tow the car. I turned it off and on 3 with the same results, but by the 4th time, the "reduced power" was gone and engine was running smooth.
I called On Star (probably shoulda called them when the car was at bad idle and they gave me 2 codes relation to Electronic Throttle Control:
P2135 and P2137.
Anyone know more about these codes?
This is the 3rd time in the past year that ive gotten the reduced enginer power warning, but the 2 previous times (2 different dealerships) I brought the car in for service, they told me that they could not do anything cause the codes had cleared and there were no "hard codes"
any ideas??

As they said, DTC P2135 is for the throttle position sensor.
"The throttle position (TP) sensors 1 and 2 are located within the throttle body asssembly. The TP sensors share a common 5-volt reference circuit and common low reference circuit...If the ECM detects that the TP sensors are not within a predicted value from each other, DTC P2135 sets."
The ECM will turn off the MIL after three starts without the problem recurring, but the code will remain in history for 40 warm-up cycles if the problem doesn't reoccur. This makes me wonder if P2135 is the code that set the last time you had the problem...40 warm-up cycles is a long time; maybe 2-3 weeks if you drive the car daily. Unless you were slow taking it in for service, they should have found the code in history.
I expect one of the throttle position sensors has an intermittent fault...the fault will probably continue and become more frequent over time until the sensor fails completely.
I can't find DTC P2137...the DTC codes in the engine controls section jump from P2135 to P2138 (accelerator pedal position sensor).

Take it in for service.
It probably won't get any better. I assume that you have not connected anything electrical down in the fuse section under the pasenger floor board. If that is not correct, disconnect it. - My 2c.

On Star stated that P2137 was also for ECM.
The only think Ive installed electrically, is a hardwired connection to the rearview mirror for my V1. I installed it the 1st week of having the car, so it's been there for all alrams, but I dont see how that could be the culprit.
It's been raining alot in NJ, so Ive only been driving the car 1-2 times per week and its not a daily driver - so the codes should not have cleared.
As for my previous experience at the dealer, I think they found the code, but said it wasn't a "hard code" which I suppose means the symptoms had gone away. Truth is, that chevy dealership did very little work on corvettes and I think that he didn't want to deal with it.
From now on, I will take it to classic chevy, as they perform service on many corvettes daily.

Here's what my ProScan software says the codes are, but I don't know what that means.
Good luck!

It means that your AC is condensating and it drips right on that (TPL)throttle Pedel linkage and a little crap can collect on that ..this is "fly by wire"...you Pedal is in the right position.... in the right positions between 18% and 22%...however your check engine light is on... maybe a traction control needs service or reduced engine speed and you are crawling along and all that is wrong is you need to clean and make sure that linkage is strait and free of any forien material so when you let off the throttle the puter sees the pedal come back to where it already is but however the wire is not coming back all the way and the puter does not know what to do so you get that code...clearing it will not fix it... and a lot of dealers employees do not know what to look for.... that is my one beef with the new vette and that is water dripping down from the AC on my feet.... now I am in Florida and I am always topless and blasting at 60 degrees max AC.in a triple black C6.......I had this happen..Took it back to my tuner who. fixed at Razors Edge and cleared the lights and now I am back to beating the crap out of it........

Too Bad none of the people that work for the dealeers have a clue on what to do and how to fix most of the stuff that comes up..... the silly Bose Radio is a typical example...... I am on my second one and now I get CD mechanical error.. I pulled the radio myself this time to addd the XM Sportscaster because I used the dash for the XM antenna and the ashtray is perfect for the unit...it fits like a hand to a glove... you take out the cigarret lighter and keep it because you need the 12 volt plug for the XM power plug which drops it to 5 volts, run the antenna up right over the AC duccts and wala... XM no antenna to woory about ... (I have a rag top) and the unit looks like it came from the factory....... but if I want my CD's I am goingto have to take it to the dealer who will pull the radio send it off and leave me musciles just like they did twice before.,.. and the Bose radio has REMANUFACTURED on it to boot....lol

. You could lose your credibility as a knowledgeable customer is a NuYawk second...I think I would just let them do their thing. When they ask you for symptoms, i.e. what the car is doing/not doing, just tell them that. Plus, what OnStar told you.

Dropped off car today for:
1. "Reduced Engine power"
2. seat Memory recall not working
3. Spacers in top
4. Rear fluid swap
Got a call saying all they ordered parts for 2 and 3 and swapped the rear fluid, but couldnt find anything wrong with the ECM (reduced power) and thay they are instructed to clear codes, test drive and return to customer (unless problem repeats) so I told them this is the 3rd time and they are ordering a new throttle body. Hopefully, that will cure it.
I have to pick up car and bring it back when all parts are in.
