MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-33
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.
