Wacky Tachometer
Today my tach started acting up. It won’t go below around 2000 when off and starts from there as if it’s zero. Torque Pro monitor is showing correct. Is there a fix besides the whole cluster?

Not sure what year you're working on but with Key Off, hold down the odometer reset button. Then while holding the reset, turn key on but don't start it. This will put the cluster in test mode and then you can let go of the reset. It should then sweep all the gauge needles and reset them to where they should be. Cycle the key and see if its reset.

Thanks!! Mine actually has the info center or whatever it’s called so I had to hold the reset and info buttons, but it worked.

Great! While you're in that test mode you can toggle through and see other parameters that the pcm is seeing. If you didn't have a scanner and were trying to diagnose something, it could come in handy.

Sometimes the little spiders will build a web that hangs up the needles.
It the test mode dos not fix it give https://circuitboardmedics.com
a call for a rebuild. They are a FTE sponsor and will get things working.
