Diagnostic Trouble Code (DTC) Detecting Criteria
CB:DTC P0607 THROTTLE CONTROL SYSTEM CIRCUIT RANGE/PERFORMANCE
1. OUTLINE OF DIAGNOSIS
Judge as NG when any one of the followings is established.
1) When the read value of throttle position sensor 1 signal is mismatched between main CPU and sub CPU.
2) When the read value of accelerator pedal position sensor 1 signal is mismatched between main CPU and
sub CPU.
3) When the sub CPU operates abnormally.
4) When the communication between main CPU
5) When the input amplifier circuit of throttle position sensor 1 is abnormal.
6) When the cruise control cannot be canceled correctly.
7) When the signal of brake SW1 and 2 is mismatched.
