The input voltage from the accelerator pedal position sensor (sub) is monitored whether which is converted normally into the digital signal within engine-ECU.
TROUBLE JUDGMENT
Ignition switch is “ON” position.
When the input voltage from the accelerator pedal position sensor (sub) is periodically to be zero, the input voltage digital value shows 0.2 V or more.
PROBABLE CAUSE
Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III diagnosis code
After clearing the diagnosis code through M.U.T.-III, ignition switch is “ON” position and confirm whether the diagnosis code is output.
