What to do when a sensor is defective
(1) Disables lean-mixture combustion.
(2) Controls the throttle valve position by using the accelerator pedal position sensor
(1st channel) signal.
(3) Disables the electronic-controlled throttle valve system if the accelerator pedal position
sensor (1st channel) signal is also defective.
(1) Disables the electronic-controlled throttle valve system.
(2) Disables lean-mixture combustion.
(3) Disables engine idle speed feedback control.
(1) Disables the electronic-controlled throttle valve system.
(2) Disables lean-mixture combustion.
(3) Disables engine idle speed feedback control.
(1) Disables lean-mixture combustion.
(1) Disables the electronic-controlled throttle valve system.
(2) Disables lean-mixture combustion.
(3) Disables engine idle speed feedback control.
(1) Error in communication between the throttle valve controller and engine-ECU
Disables lean-mixture combustion.
Shuts off fuel supply when engine speed exceeds 3,000 r/min.
(1) Error in communication between the throttle valve controller and engine-ECU
Disables lean-mixture combustion.
Shuts off fuel supply when engine speed exceeds 3,000 r/min.
The throttle valve controller controls the throttle valve opening angle by using
the accelerator pedal position sensor (2nd channel) signal.
