The problem may not have been in the sensors, but the electronics inside the instrument cluster itself. If the circuit board has corrosion or is cracked, it may interrupt the electrical signals to the motors that move the needles across the display. Consider hiring and experienced technician like one from YourMechanic who can come out and take a closer look at your erratic instrument cluster and offer a more personal diagnosis.
