Venza Reduced Engine Power

My 2017 Toyota Venza with a gasoline engine is acting up. I'm getting reduced engine power and there's an error stored in the error memory. Mileage is at 162521 km. I suspect a defective engine control unit. Any ideas?

I had similar symptoms on my Toyota Venza. Sounds like it could be a main relay issue. Have you checked that?

Main relay, huh? Where's that located and how would I check it?

It's often in the engine compartment's relay box. Think of it like a fuse box, but for relays. You'll need a multimeter to test for continuity. But honestly, with ECU issues, it's often best to let a workshop diagnose it properly. Could save you time and money in the long run.

Thanks! Turns out it was indeed the main relay, as you suspected. Cost me 120€ to get it sorted. Appreciate the help!
