Madison, fl
Just finished fixing p.i.a. Hydraulic line underneath cab. Had to take of the ecu for more hand room. Put everything back including little ground wire now when you hit the key it starts for a second then throws that code. I checked all fuses and have looked for bare wires. It says an engine speed sensor for that code? Did something we do mess it up or is this a coincidence? Thank in advance.
