Instrument Panel Cluster (IPC) Description and Operation: Tachometer

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM)/powertrain control module (PCM). The IPC receives a class 2 message from the ECM/PCM indicating the engine speed. The IPC is capable of displaying between 0-7,000 RPM. The tachometer will default to 0 RPM if the ECM/PCM detects a malfunction in the engine speed sensor signal circuit.
