The engine-ECU applies 5 V to the accelerator pedal position sensor (main).
The engine-ECU checks whether the supply voltage is within the specified range.
TROUBLE JUDGEMENT
Battery positive voltage is 8 -16 V
2 seconds later after the ignition switch has been in “ON” position or the engine has started up
The detected voltage of analog sensor reference voltage No. 1 is 5.14 V or more for 0.5 second. [Power supply for accelerator pedal position sensor (main)]
PROBABLE CAUSE
Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III diagnosis code
After erasing the diagnosis code through M.U.T.-III, ignition switch is “ON” position and confirm whether the diagnosis code is stored.
