Both my speedometer and tachometer stopped working. My speedometer stopped working first and less than a minute later, the tach stopped as well. My code reader says speed sensor which makes sense, but what about the tach?

replace the cable for the speedo as it may have been removed so that correct mileage was not recorded
the tacho gets its signal from coil impulses or ignition module so check for disconnected wires

There was a recal by ford company regarding this they should change it or upgrade and modify free of charg.

This is a tricky one. You have two sensors for your speedometer and tachometer, if one is malfunctioning then both will. Check and replace if necessary, good luck

check the vehicle speed sensor located on the transmission housing.

You have two sensors on the engine that send a signal to the computer, speedo, and tach. If just one of these sensors goes bad your speedometer and tachometer can just stop working. Check if these sensors are blocked or if broken then replace.

Good Luck!

Make sure you have installed the battery correctly red cable on the (+) and black cable on the (-) side sounds like it may be reversed this wold cause instant battery drain.

there are rechargeable aa batteries that wear out over few years and have to be replaced behind the tach on some cars.. I just did it on a BMW and the tach started waorking again as well as the gas mileage indicatoor gauge
