We have a Toyota Yaris Verso 2002 diesel D4D.
We had a problem with our accelerator pedal position sensor which caused the motor to go into limp mode.
A few year back a mechanic cleaned out the electrical connectors with contact spray and it worked OK for three years.
Now we have the problem again. Can I spray inside the potentiometer with contact spray or should I only clean the electric connector?
Toyota doesn't sell the potentiometer by itself so you have to buy the whole pedal assembly for about $700. If I find the potentiometer in a junkyard and replace it, does the computer need to be reset?
