What Does p3497 Toyota Prius mean?

By Nick Marchenko, PhD

Alright, in layman's terms, the p3497 diagnostic trouble code is pretty much telling us there's something funky going on with the cylinder deactivation system in Bank 2. So what's the deal with this? Essentially, this code is pointing at a hiccup in the engine Bank 2 of the cylinder deactivation system.

Maybe the engine oil's running a bit on the low side, or it's just clogged up and dirty. And, hey, damaged wiring could be messing with things and setting off that code. A big heads-up here: most times, like 90%, you'll see that pesky check engine light pop on and your Prius guzzling more gas. As with any ride, getting things squared away promptly ensures your Toyota Prius stays smooth and efficient.

But, if there's any weirdness or unexpected behavior in this system, the PCM's gonna jot down that p3497 code.

So, the PCM jots down code P3497 either when it spots something odd in the cylinder deactivation system or when it's struggling to work with engine bank 2's deactivation system.
