TFI faults....

I replaced my TFI 2 times before I moved it on "cooler" place. Now I have no claims.

I found this article today
Accident Reconstruction News

What is your opinion?

Well, I believe their claims are true, and Ford should have assumed responsibility for the problems, and should have changed the design more promptly after discovering the cause of the problem. However, most cases of actual injuries and property damage are not directly the result of the failed module, as a vehicle with a stalled engine can still be steered at speed, allowing the owner to pull it to a safe location. Also the brakes still work, though with increased difficulty. Any collisions can be avoided by actually knowing how to drive a vehicle, and how to be one with the vehicle you are driving, so that you immediately know when something goes wrong, and how to respond. Pablo, you are probably proof of this, you have never reported that a failed TFI put you in a dangerous position. As far as I am concerned, tires that blow out are just as dangerous, if not more so. There are a lot of things that can go wrong with a car that could be far more hazardous to the drivers and passengers on the road.

This is module from DIS. One wire is cut (wire selecting coils to actuate), no starter wire too.

My 1990 3.0L has an "almost stalling" condition that occurs while warming up under load. It shows no codes. Is there a way of testing the module either in or out of the vehicle?

The things I'm focusing on are:

" ...140C and 18volts..." and "...exposure to excessive temp..."

Is 140C "excessive"? Would a normally functioning car subject the module to 140C and 18V? Perhaps 140C can be the regular underhood temperature of cars operated in certain conditions. But I'm thinking 18V is beyond the operating range of most automotive electronics, and indicates that voltage regulator is failing.

Unfortunately, most American drivers have just the bare minimum of skills and attitude required to drive. They will most likely handle a sudden engine stall with clumsiness, and get into an accident. I've seen plenty of accidents whose initial cause were blown tires, but exacerbated by incorrect responses from the driver.

Newer had overvoltage problems, but my TFI failed becouse overheating. Changing its place solved problem easily. Why for did not do it for many years? Yes, now Ford cars have ignition module mounted on radiator.

Not sure about other vehicles but blow tire on aerostar is not so dangerouse. Easy to stop carefully.

Yes, there are more "stupid" acidents in the USA related with driver's skills, but here the problem of wreckless driving is different. Most dangerouse cars are cheap cars. Young drivers ride like on race track.

Not just young drivers...many drivers here in US think they're on racetracks while on the road, or even residential streets.

The last time one of my cars stalled in mid-turn, the steering actually fought my efforts to maintain the angle I had, and the brakes became unresponsive to gentle application. I had to jam hard to avoid hitting a curb. I can see how a typical house wife would probably not have been able to wrestle the steering wheel or stand on the brakes to avoid a collision.

Of course it's possible to drive with the PS pump disabled, but very difficult for most people, and nearly impossible for the average driver who is used to "fingering" the steering wheel to aim the car where they want to go.

Once I was helping a woman with a dead battery in her car. I had to push it out of her parking spot to get it close to the other car that we were going to get the jump from. I pushed, told her to steer in certain directions. She just could not do it...I ended up having to push while wrestling with the wheel through the window.

Manual steering is tougher when going very slow, as in pushing a car. To make matters worse, the gearing ratio for the steering is different with power assist so that running a power steering system without a pump is worse than if the car came with manual steering. I had a full sized '71 Ford that I drove for some time with no PS pump and, as I recall, the steering wheel was going to end up deformed from the intense effort I had to put into steering.

Not just the steering wheel, but also the steering shaft, and every part up to where the power assistance comes in. They will be subject to the increased stress of pushing against the faster steering ratio, and the drag of the power assist hardware.

there are small fluid channels in PS and when you turn steering wheel with PS pump disabled you move fluid throught small and thin channels. This is the additional force.
