Transmission Fluid Level Sensor Circuit Intermittent/Erratic
The P070E code indicates that the powertrain control module (PCM) has detected an intermittent or erratic signal from the transmission fluid level sensor. This sensor monitors the fluid level in the automatic transmission and sends a voltage signal to the PCM. An erratic signal can be caused by a faulty sensor, wiring issues, or low transmission fluid. This condition may lead to incorrect fluid level readings, potentially causing transmission shifting problems or damage if not addressed.
01. Most Common Causes
- Faulty transmission fluid level sensor
- Damaged or corroded wiring/connectors to the sensor
- Low or overfilled transmission fluid
- Internal transmission issues affecting sensor operation
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Erratic or harsh shifting
- Transmission slipping or delayed engagement
- Incorrect transmission fluid level reading on scan tool
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for additional transmission-related codes.
Step 2: Inspect the transmission fluid level and condition; adjust if necessary.
Step 3: Visually inspect the sensor wiring and connector for damage, corrosion, or loose connections.
Step 4: Test the sensor's resistance and voltage output per manufacturer specifications; replace if out of range.
