Description

INFOID:0000000012198526

ECM receives a rear wheel sensor signal from ABS actuator and electric unit (control unit) via CAN communi-

cation to switch combustion for the direct injection gasoline system. For the direct injection gasoline system,

refer to 

EC-630, "DIRECT INJECTION GASOLINE SYSTEM : System Description"

.

P0506 ISC SYSTEM

P0506 ISC SYSTEM

Description

INFOID:0000000012198529

The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let

into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is

varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects

the actual engine speed and sends a signal to the ECM.

The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value

memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.

The optimum value stored in the ECM is determined by taking into consideration various engine conditions,

such as during warming up, deceleration and engine load (air conditioner, power steering and cooling fan

operation, etc.).
