13B-49

Throttle position sensor 
(main)

• Controls the throttle valve position through the use of the throttle position 

sensor (sub) signal.

• Renders the amount of accelerator pedal travel as being approximately 

one-half the normal opening angle.

• Prohibits the operation of the engine speed feedback control.

• Prohibits the operation of the auto-cruise control.

• Cuts off fuel when the engine speed exceeds 3,000 r/min.

• Suppresses the engine output by stopping the electronically controlled 

throttle valve system if the throttle position sensor (sub) is also 
malfunctioning.

Throttle position sensor 
(sub)

• Controls the throttle valve position through the use of the throttle position 

sensor (main) signal.

• Renders the amount of accelerator pedal travel as being approximately 

one-half the normal opening angle.

• Prohibits the operation of the auto-cruise control.

• Cuts off fuel when the engine speed exceeds 3,000 r/min.

• Prohibits the idle speed control from learning.

• Suppresses the engine output by stopping the electronically controlled 

throttle valve system if the throttle position sensor (main) is also 
malfunctioning.

Throttle valve position 
feedback

• Suppresses the engine output by stopping the electronically controlled 

throttle valve system.

• Prohibits the operation of the auto-cruise control.

• Prohibits the operation of the engine speed feedback control.

Throttle actuator control 
motor

• Suppresses the engine output by stopping the electronically controlled 

throttle valve system.

• Prohibits the operation of the auto-cruise control.

• Prohibits the operation of the engine speed feedback control.

Switching to high-speed 
cam in Mitsubishi 
Innovative Valve timing 
Electronic Control 
(MIVEC)

• Does not switch to high-speed cam.

• Cut off fuel when the engine speed exceeds 5,000 r/min.

DIAGNOSTIC TROUBLE CODE CHART

M1131151005704

WARNING

When touching the throttle valve, surely shut off the driving circuits of the throttle valve. In 
the event that the throttle valve is operated, a finger might be injured as the result of being 
caught by the throttle valve.

CAUTION

During diagnosis, a DTC code associated with other system may be set when the ignition switch is 
turned on with connector(s) disconnected. On completion, confirm all systems for DTC(s). If DTC(s) 
are set, erase them all.
