Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello. My name is Mark and I will be assisting you today.
You really need a scan tool to check these faults as the instruments have their own control module. The sensors for the temperature, engine speed and vehicle speed go through the engine ecu and the fuel level sensor goes through the multifunction control unit. The instrument, engine and multifunction unit are all connected to the vehicle CAN bus and share information.
Please remember to rate my assistance. I don't get paid until you do.
