LandCruiser knock sensor issue

Hey, I'm having trouble with my 2016 Toyota LandCruiser (gasoline engine), it has about 173881 km on it. The check engine light is on, and I'm getting worse fuel economy and rough idling. The diagnostics point to a bad knock sensor, and maybe a bad wire or connector. Anyone seen this before?

I had something similar happen with my LandCruiser. Sounds like what I saw when my knock sensor failed. Did you check the ignition timing? That might tell you something.

Thanks for the quick reply. I haven't checked the ignition timing yet. Would bad ignition timing confirm the knock sensor is bad, or is that something else I should look into?

When my knock sensor went, it messed with the ignition timing. It could be something else, but the sensor is probably the problem. I'd get a shop to confirm before you swap any parts.

Thanks, I appreciate the help. I'll take it to a shop to check the knock sensor and ignition timing like you suggested. Thanks for sharing your experience.
