The steps in the video should work because he actually exposes the sensor before cleaning it with compressed air then wd-40. You don't want to just spray it willy-nilly.
And even if it doesn't - you haven't lost anything other than a few minutes of time.
Every vehicle you buy comes off the dealer lot. It just means you have to take delivery to use the coupon. You can order it and use the coupon if it gets here before it expires.
Many don't trust the IOLM and are doing 5K changes (or sooner) and some are doing that even with full synthetic. Overkill, IMO. The IOLM interval with factory synthetic blend is just fine.
Some of the accessory delay is managed by the devices like the radio. It gets constant power and it decides when to shut off based on timers and triggers. It also allows you to turn on the radio manually for up to 1 hour. More flexible than cutting power to the entire circuit.
It's going to be hard to prove that it was a faulty repair 2000 miles ago. I assume the root cause of the bent rod was a broken timing chain? Or was there fluid in the cylinder?
I just said that the accessory outlets are hot all the time. Opening the door gets rid of the accessory delay so you can find a suitable fuse location . You need a multimeter or a 12v test light to help find one.
