Code No. 0225 Throttle position sensor (2nd channel)
system
The throttle valve controller judges a malfunction, and then transmit the result to
the engine-ECU <M/T> or engine-A/T-ECU <A/T>.
Range of Check
D Ignition switch: ON
D The throttle position sensor (1st channel) is normal.
Set Conditions
D The sensor output voltage is 0.2 V or less for four seconds.
or
D The sensor output voltage is 4.85 V or more for four seconds, and the
output voltage of the throttle position sensor (1st channel) is 1.2 V or more.
or
D The throttle position sensor (1st channel) and throttle position sensor (2nd
channel) combination output voltage is outside 4 - 6 V.
