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

Common causes

Most likely first

  1. Faulty transmission fluid level sensor
  2. Open or short-to-voltage in the sensor wiring
  3. Corroded or loose connector at the sensor
  4. TCM input fault (less common)

How to diagnose & fix

Work through it in order

  1. Read freeze-frame data and confirm the actual transmission fluid level manually.
  2. Inspect the sensor wiring and connector for opens or shorts to voltage.
  3. Test the sensor signal against specification.
  4. 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.
