Unified Control Meter: Tachometer
WARNING: This page is about a different car, the 2002 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When the engine speed approaches the Red zone, shift to a higher gear. Operating the engine in the Red zone may cause serious engine damage.
The tachometer indicates engine speed in Revolutions Per Minute (RPM). The tachometer is regulated by a signal from terminal No. 25 of the ECM, to combination meter terminal No. 16 for the tachometer.
