The ‘safety’ issue emerges from the sensors and engine control conputers that try to meet emissions and fuel standards by precisely matching temp, spark, fuel injection, to burn as clean and efficiently as possible.
But sensors (cam shaft, crank position, misfire, ignition, ma airflow. coolant temp, etc.) WEAR OUT and the ECM (engine control computer modules) can malfunction over time.
So say an owner is sure to get such a car to the shop for regular checkups, that should ensure safety right?
No.
These parts, when they go out, tend to go out in the same time frame and mechanics (the honest ones) use electronic computer scanners to diagnose problems which don’t always detect parts that are degrading.
Well then, why not have a state law that requires an OVERHAUL of all such sensors?
In that case, you might as well as get another vehicle.
So what kind of safety incidents can be seen with these aging computerized death traps?
One example is where say the Max Airflow Sensor starts acting up, malfunctioning. You’re on the freeway driving freeway speeds. The engine rpms start doing weird things and the car dies, engine shuts off. Meanwhile, as you’re slowing down there are cars whizzing past you and you’re trying to coast to the shoulder. You’re in trouble, big trouble. And with the engine not starting, you have no hydraulic assist so steering and braking are a nightmare.
If the President indeed did propose a rollback on unsafe regulations, keeping in mind this is the Associated Press pukes that are writing this slop, I would bet the President also proposed increasing safety standards when it comes to engine reliability. The President is not stupid. If he’s getting reports of accidents and unsafe incidents resulting from ‘computerized’ vehicles that are aging, it must be an emerging trend. I would bet it’s emerging because of the sheer number of aging cars that are computerized and are a danger because their sensors and computers are going bad.
That would be MASS airflow sensor. To use to mix in a proper mass of fuel.
I have never heard of a MAF sensor causing such an issue at freeway speeds. at idle is another story. My older Fords all have/had precalibrated default data inside it can fall back on, in the event a sensor failed. Newer stuff has so many sensors that often times they can guess what data they need regardless of a failed sensor.
