communicated across the data link. Front and rear coils fire each spark plug independently (one cylinder at a time - no wasted spark). The coil also has an extra terminal to monitor current on the coil secondary circuit. This is used for knock detection and combustion diagnostics. The ignition system gives a spark near top dead center for starting. At RPM and loads above this, the system gives a spark advance that varies between 0° and 50°. The IAT, ET and TP sensors are used to provide information to the ECM to fine tune spark and fuel delivery. The VSS is used as an input for idle speed control. For Information on Related Topics S
ELECTRONIC FUEL INJECTION (EFI) SYSTEM

The engine management system consists of the following

Electronic control module (ECM). Crank position sensor (CKP). Manifold absolute pressure sensor (MAP). Intake air temperature sensor (IAT). Engine temperature sensor (ET). Throttle position sensor (TP). Vehicle speed sensor (VSS). Turn signal module (TSM) or optional, factory-installed turn signal security module (TSSM). Both include an integrated bank angle sensor (BAS). The ECM is mounted below the seat. It computes the spark advance for proper ignition timing based on sensor inputs (from CKP , MAP and TP) and regulates the low-voltage cir- cuits between battery and ignition coil. The ECM contains all of the solid state co
