Ok, so I replace a downstream o2 sensor on my 2011 Subaru legacy. Car is running fine before even ran a little to heat up sensor so I can remove easier. I removed intake chamber on top and unplugged so I can access o2 a little better. After installing car would just kick over and not start. I saw P0335 (plus all other codes) so first I removed/ checked voltage on crankshaft position sensor and ok.
I then took chamber back off and reinspected all areas even though I knew I was no where near any wires to short anything. I could hear a buzzing noise same as when you turn key to "on" position. I then noticed the main computer lock latch got unlocked (in photo) so I pushed forward to lock. Noise immediately stopped and car started notmal no codes. So, I thought I post this if someone else accidentally unlocks that clip lock when removing chamber.
