[AT] Right to repair

[James Peck]

I had a 1987 Plymouth Reliant (great car but weak electronics) that blinked out the codes using the check engine light. Yes, Ford and others had OBD1 ports in the early nineties.

The Digital Multimeter owes a lot to the development of the microprocessor chip. That space program did a lot for us. You can typically get one at Walmart General Store for under $20.00

James AT List Member and advocate of upgradeable tractor vocational training (jamesgpeck at hotmail.com); I have an Actron scanner. I remember it costing around $125.00. It works on my vehicle from the early nineties, my vehicle from the early oughties (as in 01), and a vehicle from the early twenty teens. I wonder if the scanner would have pointed to the speed sensor before and after replacement.  I wonder if the manual contains enough information to allow you to test the sensor in or out of the circuit?

Francis Robinson aka "farmer" Central Indiana USA AT List Member (robinson46176 at gmail.com); The 2005 Chrysler Town & Country I bought several years ago from an individual ran and drove great but then went into "limp" mode on the transmission. I did some studying and decided that it was the input speed sensor. I bought a new one and put it in. Zip, no change. OK, I was wrong. I took it to a busy mechanic friend and told him the things I had checked and about the new speed sensor not helping. I've known him since he first started and have used him for electronics problems a number of times. He is one of the good guys, always treated me well and while he is not free  :-)  he has always been fair. (He has retired now dang it. His son-in-law took over and I won't take anything to him.)  Anywho...  He called a bit later and he found that the new speed sensor was defective... He changed it and charged me but it was reasonable. No other problems. I had about strained my brain looking at stuff... I had even done a fluid and filter change just to get in there to look at stuff. It has done well in the years since. We have traveled in it quite a bit.
