Code No. 0225 Throttle position sensor (2nd channel)
system
Probable cause
The throttle valve controller judges a malfunction, and then transmit the result
to the engine-ECU
Range of Check
Ignition switch: ON
The throttle position sensor (1st channel) is normal.
Set Conditions
The sensor output voltage is 0.2 V or less for four seconds.
or
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
The throttle position sensor (1st channel) and throttle position sensor (2nd
channel) combination output voltage is outside 4 – 6 V.
Malfunction of throttle position sensor (2nd
channel)
Open or short circuit in the throttle position
sensor (2nd channel) circuit or loose connector
contact
