My car is only five years old but already has two sensors that have gone bad in the engine. Neither of them are vital and everything works great despite the occasional check engine light. Redundancy. It's a time intensive process to pop the head off and replace sensors. Nobody wants to pay their mechanic $100 an hour if they can avoid it.
I can't even imagine a sensor failure having zero redundancy, much less changing control inputs to a complicated system like a multi-engine jet. This is completely against everything I know about engineering and I find even discussion of this being possible to be deeply offensive. The fact that it happened twice and hundreds of people are dead is just mind boggling.
- pytyper2 8y ago"...everything works great despite the occasional check engine light..." that may make you feel better but it's not true. The life and efficiency of your engine is being reduced. What year, make, model are you driving? When you sell it do you plan on telling the next owner that you drove it religiously with the check engine light on?
- oldjokes 8y agoThe engine isn't magic, you can read the codes yourself, figure out what they mean, look up the replacement guidelines yourself, etc. It's really simple actually, anyone can do it.
- linuxftw 8y agoFailed sensors can lead to premature failure of various components, especially catalytic converters: http://ricksfreeautorepairadvice.com/causes-catalytic-converter-go-bad/ http://ricksfreeautorepairadvice.com/causes-catalytic-conver... Don't put off a $150 job and cost yourself a $2k job. Most sensor replacements don't require removing the cylinder heads.
- oldjokes 8y agoYou're assuming I don't know what the codes are and that they are potentially harmful, neither of which is true.
