P0720

Test 294-297:

Test 298:

SYMPTOM:
P0720-OUTPUT SENSOR ERROR

When Monitored and Set Condition:
P0720-OUTPUT SENSOR ERROR
When Monitored: The transmission gear/speed ratio is monitored continuously while the transmission is in gear. This code is set if the gear/speed ratio is not correct for a period of time.
Set Condition: A hard code is set within 3 seconds, an intermittent code sets with 3 seconds, an intermittent code sets within 15 seconds. Code P0720 sets if there is an excessive change in input RPM in any gear.

POSSIBLE CAUSES
- CHECKING SYMPTOMS AND POSSIBLE CAUSES
- LOW BATTERY VOLTAGE CAUSING SYMPTOM
- INTERMITTENT CODE P0720
