Instrument Panels - Electronic: Operation: Gauges: Tachometer

The electronic tachometer display is integrated into the electronic instrument cluster. The tachometer display consists of 46 bars. It indicates engine rpm from 0 to 8000 rpm, according to the number of bars illuminated. From 0 to 1000 rpm, each bar represents 100 rpm. From 1000 to 8000 rpm, each bar represents 200 RPM. The Crankshaft Position (CKP) sensor, which is built into the distributor, monitors engine speed and sends a sine wave signal to the Powertrain Control Module (PCM). The PCM transforms the CKP signal into a digital signal, which is sent to the tachometer display.
