Code No. P0220 Accelerator pedal position sensor (1st
channel) system
Probable cause
Range of Check
Accelerator pedal position sensor (2nd channel) is normal.
Communication between the engine-ECU <M/T> or engine-A/T-ECU <A/T>
and the throttle valve controller is normal.
Set Conditions
The output voltage of accelerator pedal position sensor (1st channel) is 0.2
V or less for one second.
or
The output voltage of accelerator pedal position sensor (2nd channel) is 2.5
V or less, and that of accelerator pedal position sensor (1st channel) is 4.5
V or more for one second
or
The difference between accelerator pedal position sensor (1st channel) and
accelerator pedal position sensor (2nd channel) output voltages is 1.0 V or
more (i.e. the throttle opening angle changes slightly).
or
The output voltage of accelerator pedal position sensor (1st channel) is
1.875 V or more for one second when the accelerator pedal position switch
is turned on.
Malfunction of accelerator pedal position sensor
(1st channel)
Open or short circuit in the accelerator pedal
position sensor (1st channel) circuit or loose
connector contact
Accelerator pedal position switch seized ON
Malfunction of throttle valve controller
Malfunction of engine-ECU <M/T>
Malfunction of engine-A/T-ECU <A/T>
