Does anybody know how the 2016 accord derives the tach reading?
Which sensor could it be using? The engine works, but the tach gauge does not move. I don't have a scanner to check, but I assume the ECU knows the engine RPM if it's able to run??

I would be guessing the Torque Converter Turbine Speed Sensor might be the one that is used for the gauge? It's sharing a common wire with the Engine Temp Sensor 1, and both Tach+Temp are not working on the cluster.

Also seems by not having temp sensor working, then the coolant thermostat never opens? Is the thermostat/flow of coolant ECU controlled on this car?

You have a 3 year/36,000 mile basic, 5 yr/60,000 warranty. Take it to the dealer.

Trying to fix an Accord that had a minor accident.. I'm pretty sure warranty no longer applies now, because any problem could be due to the accident.
I'll figure it out, going to check wiring diagrams soon.
