Previa hybrid engine power loss

I've got a 2012 Toyota Previa, hybrid engine, with about 90k km. I've noticed a significant drop in engine power, especially when accelerating. The check engine light is on, pointing towards a defective throttle valve. I've checked the air intake, cleaned the throttle body as best I could, but the issue persists. Could a faulty accelerator pedal module cause these symptoms? Anyone experienced something similar?

I had a similar issue with my Previa a while back: reduced power and the check engine light. Does it feel like it's going into limp mode? Any delay in engine response when you hit the gas?

Yeah, it definitely feels like limp mode sometimes. And there's a noticeable delay when I press the accelerator, like the engine isn't getting the signal right away. It almost feels like the engine is idling badly. Was your issue definitely related to the throttle system?

Sounds like the exact same problem I had. I suspected the throttle sensor first, but it turned out the entire throttle body needed replacing. I'd advise getting it checked out at a workshop.

Thanks for confirming! Sounds like I'm on the right track then. Took it to a shop and, yep, throttle valve was shot. New one fitted, cost me about 265€, and it's running like a champ again. Appreciate the help!
