Operation Section G643 Electronic Controlled LP Engines (If Equipped) General Description EMS Fuel Filter Fault Light LP Fuel Line Key switch Fuel Lock Main PWR Relay Foot Pedal APP Coolant Line Converter Air Cleaner Vacuum Line Mixer DBW Throttle TPS TMAP Ignition Coil SECM Coolant Temperature Sensor Muffler Engine speed is monitored by the SECM through a variable reluctance (VR) sensor. Intake manifold air temperature and absolute pressure is monitored with a (TMAP) sensor. The MI-04 is a drive by wire (DBW) system connecting the accelerator pedal to the electronic throttle through the electrical harness, mechanical cables are not used.
A throttle position sensor (TPS) monitors throttle position in relation to the accelerator pedal position sensor (APP) feedback. Even engine coolant temperature and adequate oil pressure is monitored by the SECM. The SECM controller has full adaptive learning capabilities, allowing it to adapt control function as operating conditions change. Factors such as ambient temperature, fuel variations, ignition component wear, clogged air filter, and other operating variables are compensated. 71
