INFOID:0000000005274028
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0720” with CONSULT-III or 1st judgment flicker without CONSULT-III is detected
under the following conditions.
- When TCM does not receive the proper voltage signal from the sensor.
- After ignition switch is turned “ON”, irregular signal input from vehicle speed signal before the vehicle starts
moving.
Possible Cause
