1998 Nissan Frontier guages malfunctioning?

Question

The heat needle goes to full hot and stays when starting. The tachometer reads 500 rpm when running regardless of true rpm. Odometer reads 99999, but trip odometer works. Speedometer totally erratic. Anyone know what is wrong? Truck is running fine otherwise, although service engine light soon is on, but it has been for long time.

Answer 1

You did not state that the transmission acts weird it is a automatic? Your needing a instrument cluster All or part have a Nissan tech diagnosis it. You might come across the same model in a wrecking yard. Of course your odometer may have to be reprogramed (spedo shop) about $ 25. The Code is most likely PO-500 speed sensor.
