Instrument Panel Cluster (IPC): Tachometer

The Powertrain Control Module (PCM) uses the Crankshaft Position (CKP) sensor to measure the engine Revolutions Per Minute (RPM). The Instrument Panel Cluster (IPC) uses the engine Revolutions Per Minute (RPM) data message from the Powertrain Control Module (PCM) to control the tachometer.

The base and optional Instrument Panel Cluster (IPC) tachometers appear differently but function the same. The base Instrument Panel Cluster (IPC) uses an analog gauge. The optional Instrument Panel Cluster (IPC) uses a digital display that provides a 6,000 Revolutions Per Minute (RPM) bar graph or a simulated 7,000 Revolutions Per Minute (RPM) analog gauge display depending on the selected display mode.
