Output Speed Sensor Circuit
Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
The transmission's output speed sensor signal is unreliable, so the speedometer and shift points may be affected.
2Common causes
- Faulty output speed sensor
- Damaged wiring or connector
- Damaged sensor ring
- Low or dirty transmission fluid
- Internal transmission fault
3Can I drive?
If the transmission shifts normally, drive gently to a workshop. If it slips, jerks, or will not shift, stop driving and have it checked.
