P0720 means the transmission control module is not receiving a proper signal from the output speed sensor. This sensor measures how fast the transmission output shaft rotates, which determines vehicle speed and helps the TCM calculate gear ratios and shift points.

P0720 è un codice diagnostico di guasto relativo a trasmissione, classificato con gravità high. Quando la centralina (ECU) del tuo veicolo rileva questa condizione, memorizza P0720 e accende la spia motore.
Se il tuo veicolo ha attivato P0720, potresti notare uno o più di questi sintomi:
Ecco le cause più comuni di P0720, ordinate in base alla probabilità che siano la causa del problema:
No, risolvi subito il problema. Without a valid output speed signal, the transmission cannot manage shift timing and the speedometer may read incorrectly. This affects ABS and stability control systems as well. Drive only to a garage.

The W204 and W205 C-Class with the 722.9 (7G-Tronic) transmission uses a speed sensor integrated into the conductor plate. P0720 on these models typically means the conductor plate is failing and the entire unit needs replacement. Individual sensor replacement is not possible on the 722.9.

The Astra H and J with the Aisin AF17/AF22 automatic transmission trigger P0720 due to the output speed sensor failing from heat exposure. The sensor is located at the bottom of the transmission and is easy to access. A straightforward and inexpensive repair on these models.

Octavia models with the DQ200 and DQ250 DSG transmissions share the same output speed sensor design as the VW Golf. On DSG models, the sensor is part of the mechatronic unit, making individual replacement more complex. The conventional 6-speed Aisin automatic used in some Octavias has an externally mounted sensor that is simpler to replace.

Focus Mk2 models with the 4F27E automatic and Mk3 models with the Powershift DCT can both trigger P0720. On the 4F27E, the output shaft sensor is externally mounted and cheap to replace. On the Powershift, the sensor is internal to the TCM housing and failure often requires TCM replacement.
Questi codici compaiono spesso insieme a P0720 o indicano problemi correlati:
P0720 means the output speed sensor on your transmission is not sending a valid signal. This sensor measures how fast the output shaft spins, which tells the car its road speed and helps the transmission decide when to shift.
Yes. Many vehicles use the output speed sensor signal for the speedometer. If the sensor fails, your speedometer may read zero or fluctuate wildly, and cruise control will stop working.
On most vehicles, yes. The sensor is externally mounted on the transmission case and can be replaced with basic tools. The part costs 25-120 EUR and replacement takes 30-60 minutes for a competent DIYer.
Yes. The ABS and stability control systems use vehicle speed data. A faulty output speed sensor can trigger ABS and ESP warning lights because the system detects conflicting speed signals.
P0715 relates to the input (turbine) speed sensor at the front of the transmission, while P0720 relates to the output speed sensor at the rear. The input sensor measures engine-side speed, the output sensor measures wheel-side speed.
