P070CTransmission Fluid Level Sensor Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- Fluid level sensors in the transmission sump report the oil level to the transmission module as a voltage; an Allison patent converts it to millimetres and only accepts readings with the vehicle at rest, warm fluid, low input speed and a tilt correction. Such sensors are mainly found in heavy automatic transmissions. No manufacturer document available to us uses this code. P070C means the sensor signal is below its lower limit – typically the signal wire shorted to ground or a sensor shorted internally. Because the oil level does not usually affect emissions directly, a rating without the check engine light is likely; expect a transmission warning or a missing level display. An actually low oil level is P070F.
