P070D
Transmission Fluid Level Sensor Circuit High
Transmission / fluid level sensor
Generic OBD-II
High
What it means
P070D means the transmission control module sees a higher-than-expected voltage from the transmission fluid level sensor, usually from an open circuit or a short to voltage. The transmission generally still works, but the fluid-level reading it reports may be unreliable, so it is worth confirming the actual level and repairing the sensor or wiring.
High
Can I keep driving? Usually drivable — the transmission still operates, but the fluid-level reading may be unreliable, so verify the actual level and get it checked.
Common symptoms
What you'll notice
- Check-engine light on
- Transmission fluid-level warning message may appear
- Inaccurate or implausible fluid-level reading
- Often no change in how the car drives
Common causes
Most likely first
- Faulty transmission fluid level sensorLikely
- Open or short-to-voltage in the sensor wiringCommon
- Corroded or loose connector at the sensorCommon
- TCM input fault (less common)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the actual transmission fluid level manually.
- Inspect the sensor wiring and connector for opens or shorts to voltage.
- Test the sensor signal against specification.
- Replace the fluid level sensor if it fails testing, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P070D?+
Usually yes, but because the fluid-level reading may be wrong, check the actual level so you are not running the transmission low.
Can I just clear P070D?+
It will return unless the sensor or its wiring is repaired.
