P070DTransmission Fluid Level Sensor Circuit High
- 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. P070D means the sensor signal is above its upper limit – typically an open signal or ground wire, pulled up inside the module, or a short to positive. 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. The opposite fault is P070C.
