P2101: TVA (System) (warning lamp flashes: 28)
P2102: TVA (Short) (warning lamp flashes: 28)
P2120: Acc Switch (warning lamp flashes: 65)
P2122: Acc Sensor 1 (Low) (warning lamp flashes: 24)
Generation condition
The throttle electronic drive unit has judged that the power supply to intake throt-
tle was faulty or the throttle position sensor was faulty.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
Possible causes
• Open-circuited or short-circuited harness between electronic drive unit and in-
take throttle
• Malfunction of each connector
• Malfunction of motor (built in intake throttle)
• Malfunction of throttle position sensor (built in intake throttle)
• Malfunction of electronic drive unit
• Malfunction of electronic drive unit relay
Generation condition Throttle electronic drive unit judges intake throttle shorted.
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit
• Injection quantity is limited.
• Exhaust gas recirculation control is stopped.
• Throttle control is stopped.
Possible causes
• Open-circuited or short-circuited harness between electronic drive unit and in-
take throttle
• Malfunction of motor (built in intake throttle)
• Malfunction of throttle position sensor (built in intake throttle)
• Malfunction of electronic drive unit
• Malfunction of electronic drive unit relay
Generation condition
Accelerator pedal switch signal is abnormal when compared with outputs of ac-
celerator pedal position sensors 1 and 2.
Recoverability System recovers if signal becomes normal with starter switch in ON position.
Control effected by electronic control unit Effects no special control.
Possible causes
• Open-circuited or short-circuited harness between engine electronic control
unit and accelerator pedal switch
• Malfunction of each connector
• Malfunction of accelerator pedal switch
• Malfunction of engine electronic control unit
Generation condition
Accelerator pedal position sensor 1 voltage is at or below the specified value
(0.49 V).
Recoverability
System recovers if any valid signal is input when starter switch is turned from
OFF to ON (the warning lamp does not go out unless 3 consecutive valid signals
are input).
Control effected by electronic control unit Control is carried out using output from accelerator pedal position sensor 2.
Possible causes
• Open-circuit or short-circuit of harness between engine electronic control unit
and accelerator pedal position sensor 1
• Malfunction of each connector
• Malfunction of accelerator pedal position sensor 1
• Malfunction of engine electronic control unit
