Neither the speedometer nor the tach are working. Is it a fuse or something else?
There are 2 sensors on the engine that sent a signal to the computor and speedometer and tach. When one of these goes bad it can make the speedometer and tach go all over the place and also just stop working. This can also cause all types of engine running problems because the information being sent to the PCM will be incorrect all so. The units are easy to replace once you find them, it seems that they are located in different areas of the engine with each year the vehicle was put out.
I have a 98 dodge neon my speedometer works then stop working when i was driveing the car i put a new speedsenor in and it works find it on the trann and it not that hard to fixs it cost me $25 to fix it
SOURCE: Both my speedometer and tachometer stopped
The speed sensor can be tested with a scanner. Only take 10 minutes, If it works then your instrument cluster took a dive. Same thing with the RPM. If the scanner sees it then the cluster is bad. Getting it diagnosed properly is your best bet. You can get the cluster rebuilt for alot less than new. modulemaster.com does them.
