Vent: Those knock sensor codes that made me chase ghosts for 6 weeks
So I had a p0327 code on my 02 Camry and I swapped the sensor, checked wiring, even replaced the harness connector. 6 weeks of testing and I finally found it was a tiny crack in the intake manifold gasket letting air in. That stupid air leak was causing the knock sensor to freak out and I wasted $200 on parts I didn't need. Anyone else spend forever chasing a code that turned out to be something simple like a vac leak?

Vented about that same p0327 code on my 04 Tacoma, chased it for weeks before finding a split vacuum line behind the intake. The knock sensor picks up vibrations from the engine knocking from a lean mixture, so a small vacuum leak messes with the air fuel ratio and sets it off. Always start with a smoke test before throwing parts at it, that would have saved me 100 bucks and a pile of frustration.
