Circuit Description

WARNING: This page is about a different car, the 2004 Suzuki Swift + and 2004 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

The engine control module (ECM) creates the fuel gage output signal by pulsing the circuit to ground. The ECM monitors the voltage on the fuel gage output circuit. If the ECM determines that the voltage is out of the normal operating range, a DTC sets.
