Engine Speed

WARNING: This page is about a different car, the 1987 Toyota Supra. However, it is still accessible from the selected car via links, so may be relevant.

Engine speed signal information is received from the ignition coil. These signals are used by ECU for fuel injection duration control and spark advance system.
