P0716 Speed sensor: reading or operation not right (input shaft, "A")

By: Diagno editorial team · Updated: 2026-10-15

P0716 means: Speed sensor: reading or operation not right (input shaft, "A"). The speed sensor gives the computer the vehicle speed. Drive gently and have the car checked soon. The repair usually costs about €50–300 in Estonia. The most common cause: faulty speed or ABS sensor.

What it means

The speed sensor gives the computer the vehicle speed. If the signal drops out, the speedometer, gear changes, ABS or cruise control may misbehave. There is a signal, but the reading or operation isn't plausible. The cause may be the part itself or a real mechanical fault.

What you may notice

• Speedometer dead or jumping
• Automatic gearbox shifts wrongly
• Cruise control doesn't work
• Engine light on

What could be wrong

1. 1Faulty speed or ABS sensor
2. 2Sensor wire or connector
3. 3Sensor tone ring dirty or rusty
4. 4Gearbox or ABS module

Repair difficulty: Moderate

What you can check yourself

Check whether the speedometer works. If the ABS light is also on, the fault is probably in a wheel sensor. You can check the simple things yourself, but the repair is best done in a workshop.

How we fix it

1. We read the sensor on the diagnostic tool and compare it with other sensors
2. We check the connector, supply and ground
3. We repair the wiring or replace the sensor
