Transmission Fluid Level Sensor Circuit intermittent/Erratic

Where it lives

For P070E, the circuit described runs through the sensor. The description of P070E reports a fault at the sensor.

Check these first

• A failing transmission fluid level sensor
• Loose or corroded sensor connector pins
• An intermittent short in the sensor wiring
• Low or foamy transmission fluid
• A fault in the TCM reading the sensor

What to do next

1. Check the fluid level and condition first
2. Wiggle test the sensor connector while watching live data
3. Inspect the sensor wiring for chafing or corrosion
4. Replace the fluid level sensor if the signal drops out
5. Check the TCM connector if the sensor tests good
6. Clear the code and retest
