S10 limp mode throttle valve issue
Summary of the thread
A 2017 Chevrolet S10 is experiencing limp mode with reduced engine power and an active check engine light, suspected to be due to a defective throttle valve. A similar issue was resolved by replacing the accelerator pedal module, which can cause delayed throttle response and inefficient engine performance. The suggested solution is to have the vehicle checked by a workshop to confirm the issue and replace the faulty module, which typically costs around 265€. After replacement, the vehicle should return to normal operation.

Yes, exactly! There's a definite response delay. I wasn't sure about the accelerator pedal module. If the electronics are defective, what am I looking at in terms of replacement cost and how does it affect fuel efficiency and air flow?

That response delay confirms it, I think. If it is the accelerator pedal module, you're looking at a bill around 265€. Regarding fuel efficiency and airflow, a defective module can cause the engine to run less efficiently, as the air/fuel mixture won't be optimal. It's best to get it checked out by a workshop before it causes more damage.

Thank you so much for the advice! It sounds like I'm headed to the workshop. I really appreciate the help diagnosing this issue. Your input regarding the electronics and potential costs was invaluable. Turns out, it was indeed the accelerator pedal module. I had it replaced for 265€ as you predicted, and now my S10 is running smoothly again.

I had something like that happen with my S10. Reduced engine power and the check engine light sounds familiar. It could be the accelerator pedal module or some faulty electronics messing with the throttle valve control. Think of it like a clogged artery, starving your engine. Does it feel like a delay when you press the accelerator?
