Love bites from removing a O2 sensor electrical connector between the engine and firewall.
It almost looks like someone intentionally decided to make it bad on the Honda Pilot. Easy maintainability was not a engineering concern. When I design something for work I always include easy maintainability as a major point in the specification.Familiar with that issue. I know it was hard when i did one, but I have no idea how knicked up i got. I had trouble getting the connector off.
The engine ECU system was obviously designed to be built independently of the car with physical space constraints but little thought was given IMO to the actual position for easy access (without playing 'twister' across the engine compartment) within that limited space to a sensor with a limited life time and high failure rate in normal usage.I agree re: easy maintainability. But environmental constraints come first. I.e., physical space available in an engine compartment.
When building an animatronic, I always consider how a replacement of a component will be done. That having been said - I’ve never had to replace a component. You know that the first component to fail will be the one for which I decided it would never fail.
I use a external keep-alive battery when replacing the battery in modern cars. A simple diode isolated 9V battery into a power port works for short periods.Modern cars are not designed to be messed with by joe-public – that way franchise garages can make their money charging a premium for their services.
The O2 sensor (post cat) on my Mini Countryman (BMW) requires a specialist tool for removal. Recently the alternator started over-charging; replacement requires removal of the front bodywork of the vehicle. Replacement of the battery also involves removal of vehicle bodywork and proprietary software/OBD connection to reset the vehicle electrics.
On the plus side, the remote fob is fitted with a rechargeable battery which is recharged wirelessly when docked in its holder.
Or fake it and charge anyway. Case on point. I have a 2007 Ford F150 with the 5.4L V-8 Triton engine. The spark plugs have been the subject of lawsuits, as they were originally 3-piece and break off in the cylinders. That is not good. Some people have had to remove the heads to do their first change. (Here's one of umpteen Google hits about them: http://www.fourwheeler.com/how-to/engine/1507-replacing-troublesome-ford-triton-54l-v8-spark-plugs/ ) My local Ford dealer wanted $1000 + time if any broke. I figured that was the wrong incentive.Modern cars are not designed to be messed with by joe-public – that way franchise garages can make their money charging a premium for their services.
Holy crap, no kidding. My van had a transverse V6, so the rear 3 plugs were quite a challenge. I had to remove the windshield wipers, as I recall, and a bunch of other stuff. Shops supposedly would drop the engine instead to save time. Good thing the plugs lasted 100k miles.Total insanity.
