Detonation (Knock) Retard Operation

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2003 Mazda Tribute, 2003 Mazda Protege5, 2003 Mazda Protege, 2003 Mazda MX-5 Miata, and 2003 Mazda MPV. However, it is still accessible from the selected car via links, so may be relevant.

Ignition retard system consists of a Knock Sensor (KS) and PCM. The KS detects engine detonation (knocking) in the engine and sends a signal to the PCM. The PCM retards ignition timing until KS input is no longer present.
