Hello Pros, I’m getting the Service Stabil Trak warning just before “Reduced Engine Power” then have to pull over- kill the engine- remove keys- open and close driver door- and while waiting 10 seconds before a restart and continue on my way, I glance at my reflection in the rear view to judge the depth of my frustration.
It seems to drive further if I turn off Traction Control 1st thing when I start the car and the issues come when I begin to slow down for traffic, red lights, stops, etc.
For a little insight, we got the car in 2020 as a gift with 113k miles and no known issues. Shortly afterwards the water pump in/out hoses disintegrated and replaced then the water pump. In ‘21 the car wouldn’t shift into 2nd and 3rd occasionally and was told that it could be Wave Plate disintegration particles?
Also, in May of this year she began overheating with no visible leaks, so I added some FiberLock HG and Block Repair which did the trick. Great stuff btw.
I’m trying to locate my scanner and once found I’ll drop the codes here. Until then, any help will be greatly appreciated.

Here are the codes:

P0011- A Camshaft Position Timing Over- Advanced or System Performance Bank 1
P0014- B . . , Etc.
P0121- Throttle/Pedal Position Sensor/Switch A Circuit Range/Perf.
P0330- Knock Sensor 2-Circuit Bank 2
P0700- Trans. Ctrl. Sys. (MIL Request)
P1400- Manufacturer Ctrl.
P1516-
P2135- Thrott/Pedal Pos. Sensor/Switch A/B Voltage Correlation
P0121- / / Switch A Circuit Rng/Perf

Hope this helps.
Thanks for reading my rambling.

So, the car is going into limp mode, these codes:

P0121- Throttle/Pedal Position Sensor/Switch A Circuit Range/Perf.

and

P2135- Throttle/Pedal Pos. Sensor/Switch A/B Voltage Correlation

Are the ones I think ae causing the problems, I would service the throttle body first and then clear all codes here is a guide to help walk you through the steps and instructions for your car in the images below.

If you leave the wiring connected you should not need to relearn the throttle actuator. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.

Thank you, Ken, and thanks to daylight saving time I’ll have to try this tomorrow with more daylight, saving time and money. I’ll definitely upload pics or a video to share.

That did the trick. I tried to upload some pics and a video but it all disappears when I click reply. Tried 3 times to no avail.
Make that 6 times.
