Sensor/switch/actuator Description (115A)
ECU Determines the engine operating conditions according to the input signals from
the sensors, and sends output signals to operate the actuators to perform the
various control functions
Pulser coil Detects the engine speed/crankshaft angle
Throttle position sensor (TPS) Detects the throttle opening valve
Air pressure sensor Detects the intake air pressure
Air temperature sensor Detects the intake air temperature
Oil pressure switch Detects oil pressure decrease
Thermo sensor Detects cooling water temperature
Shift position switch Detects when the gear shift is in the N position
Engine shut-off switch Stops the engine forcibly
Injector Injects fuel
Ignition coil Activates the ignition
High-pressure fuel pump Pressurises the fuel and sends the fuel to the fuel rail
Idle speed controller (ISC) valve Adjusts the flow of air to the engine when idling
Vapor shut-off valve Controls the amount of vapor gas to be sent from the vapor separator to the
intake system
Knock sensor (F115A only) Detects engine knocking
Sensors, switches and actuators
The table below gives a comprehensive breakdown of the
various sensors, switches and actuators making up the
electrical control system.
