2013 Fiesta 5 Speed Manual Hatch. 1.6 liter. I posted several years ago about throttle body control problem. Answers I got were that the $600 control had to be replace. not repairable. Moisture inside causing corrosion on contacts. Still have the problem sometimes. Usually happens after it rains or severe temperature change. I do not think it is throttle controller. Corrosion is not going to go away because I turn the ignition on and hold the throttle and brake pedal down for 20 seconds.
I am thinking it is the wiring harness connections. Found one at the throttle control. Where else does the harness have plugs and sockets between the throttle control and the throttle pedal inside the passenger compartment? What can I use to dry them out and what can I use to clean the tiny metal bits inside the connectors? What to use to keep moisture from getting in them. These connectors are similar to the ones on 3 gen Escorts. Up to 6 tiny pins and holes in each harness connector. On Escorts the pin connections tend to loose contact.
I can go months without having any problem. Once it happens I just turn the engine off, turn ignition on and hold the pedals down for 20 seconds and am then good for the next 6 months or until it rains a lot. That's easier than spending $600 for something I probably don't need.
