What it means
The transmission control system has detected that the transmission fluid level is too low. The code does not specify the cause; check the level using the vehicle's prescribed procedure.
At a glance
- Usually lights the check-engine light
How it works
The transmission control system monitors fluid level using its level sensor or related inputs. P070F indicates that the system has detected a level below its acceptable threshold; it does not identify whether fluid leaked, was underfilled, or the reading is faulty.
Common causes
Most likely first.
- Transmission fluid leak
- Incorrect fluid level after service
- Faulty fluid level sensor or its wiring
- Internal transmission fluid loss
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
How to diagnose it
- Record freeze-frame data and check the scan tool's fluid-level reading and any related transmission warnings.
- Inspect for leaks around the transmission case, cooler lines, pan, and other fluid-carrying connections before adding fluid.
- Check fluid level using the vehicle's prescribed procedure and specified fluid, because the correct method varies by vehicle.
- If the level is low, correct it using the specified procedure and inspect for a continuing leak or evidence of incorrect service fill.
- If the level checks correctly, inspect the level sensor wiring and connector, then test the sensor according to the manufacturer's specification.
Common fixes
- Repair an external transmission fluid leak at the affected seal, line, pan, or connection.
- Correct an underfill using the vehicle's specified fluid and level-checking procedure.
- Repair a faulty fluid level sensor connector or wiring if the actual level is correct.
- Replace the fluid level sensor if it fails testing and the level is correct.
Can I keep driving?
Avoid driving until the fluid level is checked; do not continue if it is below specification, leaking, or the transmission slips or shifts abnormally. Driving with too little fluid can quickly overheat and damage the transmission.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
