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

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
