Damaged, chafed or corroded wiring to the fluid level sensor; Poor connection or water or fluid ingress at the sensor or transmission connector; Faulty fluid level sensor, often combined with the temperature sensor in the sump or valve body; Actual fluid level too low or too high, or aerated or contaminated fluid causing erratic readings; Low battery voltage or poor earth or supply to the transmission control unit; Fault in the transmission control unit or an outdated calibration (model dependent).

What it means

P070E is the generic code for an intermittent or erratic signal from the transmission fluid level sensor circuit. The transmission control unit has seen the sensor signal jump, drop out or change in a way that does not fit a stable fluid level. It does not necessarily mean the fluid level is wrong, only that the reading cannot be trusted.

Symptoms

Gearbox warning light or check engine light on
Fluid level warning or fluid level reading on the dash flickering or showing an implausible value
Harsh, delayed or flared gear changes in some cases
Transmission defaulting to a limited mode or fixed gear (model dependent)
No noticeable symptoms other than the warning light

Possible causes

Damaged, chafed or corroded wiring to the fluid level sensorlikely
Poor connection or water or fluid ingress at the sensor or transmission connectorlikely
Faulty fluid level sensor, often combined with the temperature sensor in the sump or valve bodylikely
Actual fluid level too low or too high, or aerated or contaminated fluid causing erratic readingspossible
Low battery voltage or poor earth or supply to the transmission control unitpossible
Fault in the transmission control unit or an outdated calibration (model dependent)rare

How to diagnose

Read all stored and pending codes and note the freeze frame data, including fluid temperature and when the fault occurred
Check for other transmission, battery or communication codes that might point to a wider electrical issue
Inspect the wiring and connectors between the transmission and control unit for chafing, corrosion, fluid contamination and loose pins
Check battery condition and charging voltage, and the main supply and earth connections to the transmission control unit
Check the fluid level and condition using the manufacturer's procedure, which varies by model and often needs a set fluid temperature
Monitor the live fluid level and temperature sensor data while wiggling the harness to look for dropouts
Test the sensor circuit for supply, signal and earth against the manufacturer's wiring data and specifications
Check for any applicable software updates or technical service bulletins for the specific model

How to fix

Repair or replace damaged wiring and clean or replace faulty connectors
Replace the fluid level sensor, or the sensor assembly if it is not sold separately (model dependent)
Correct the fluid level and replace degraded or contaminated fluid, using the specified type and procedure
Repair battery, supply or earth faults affecting the control unit
Update the transmission control unit software only if an outdated calibration is a known cause for the vehicle, or repair or replace a faulty unit as a last resort

Can I keep driving?

Medium severity

The car can usually be driven short-term if it shifts normally, but get it checked soon because the fluid level cannot be monitored reliably. If it shifts harshly, slips or goes into limp mode, limit driving to avoid transmission damage.
