Circuit Description
WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
The ECM creates the engine speed output signal using a Pulse Width Modulated (PWM) Signal based on information received from the Crankshaft Position (CKP) sensor. If the ECM determines the failure in the circuit, a DTC sets.
